In the Gospel, the passage concerning the discernment between good and bad through their fruits is indeed a pivotal teaching of Jesus Christ. This instruction is found in the Gospel according to Matthew:

Article 1. Whether the teaching of Jesus about recognizing good from bad through their fruits is essential for discernment?

Objection 1. It seems that this teaching might be too simplistic. For it is written elsewhere that "The heart is deceitful above all things, and desperately wicked: who can know it?" (Jeremiah 17:9). This suggests that external actions (fruits) might not truly reveal the inner quality (good or bad) of a person or teaching.

Objection 2. Further, St. Paul warns that "Satan himself transforms himself into an angel of light" (2 Corinthians 11:14). This implies that evil might appear good, making it difficult to judge solely based on fruits.

On the contrary, it is written, "Wherefore by their fruits you shall know them" (Matthew 7:20). This indicates that Jesus explicitly teaches the evaluation of spiritual and moral quality based on observable outcomes or effects.

I answer that, in the context of this teaching, "fruits" metaphorically represent the actions and consequences of one's life or teachings. As I have noted in the Summa Theologica, good trees bear good fruit, and bad trees bear bad fruit, mirroring the principle that a good cause brings about good effects. Thus, by examining the fruits—namely, the outcomes of actions or the tangible effects of teachings—one can discern the moral and spiritual quality of the source. This method of discernment is crucial, as it offers a practical way to evaluate the authenticity and goodness of individuals and their teachings in a world where appearances may deceive.

Reply to Objection 1. While the heart is indeed deceitful, the fruits of which Jesus speaks are not mere superficial appearances but the real outcomes of one's actions and teachings over time. These outcomes provide insight into the true nature of the heart, despite its potential for deceit.

Reply to Objection 2. Although evil can masquerade as good, the enduring fruits (or consequences) of actions and teachings will ultimately reveal their true nature. Evil cannot produce genuinely good fruits in the long term, as its destructive nature will eventually become apparent.

Article 2. Whether the criterion of judging by fruits is in conflict with the teaching on natural law, where acts may be deemed wrong in themselves?

Objection 1. It seems that judging by fruits is fundamentally at odds with the concept of natural law. For natural law asserts that some actions are intrinsically evil, regardless of their outcomes. Hence, if an act is intrinsically wrong, the consideration of its fruits should not alter its moral evaluation.

Objection 2. Further, Aristotle, whose philosophy influences the concept of natural law, emphasizes the importance of virtuous acts as ends in themselves, not merely for their consequences. This suggests a prioritization of the nature of the act over its outcomes, which seems to contradict the principle of judging by fruits.

On the contrary, both principles can be harmoniously understood within the broader framework of moral theology. The natural law teaches that certain acts are intrinsically disordered due to their deviation from the natural ends set by God. This intrinsic disorder is a kind of "fruit" in itself, insofar as it signifies a deviation from the good that human actions are meant to achieve.

I answer that, the teaching on natural law and the criterion of judging by fruits are not mutually exclusive but rather complementary aspects of moral evaluation. Natural law provides the foundational principles that determine the inherent morality of actions based on their alignment with human nature and ultimate ends. Judging by fruits, in turn, is a method of discerning the moral quality of actions or teachings through their observable outcomes, especially in cases where the intrinsic morality of an act is not immediately apparent.

Natural law asserts that certain actions are intrinsically evil and thus bear bad fruits in the moral order, even if their immediate consequences seem beneficial. Conversely, good actions, according to natural law, lead to the flourishing of human nature and thus produce good fruits. In this sense, the fruits of an action can reflect its alignment with natural law.

Reply to Objection 1. While natural law does determine the intrinsic morality of certain acts, the observation of fruits is not irrelevant. The fruits of an action often reveal its alignment or misalignment with natural law over time. Thus, rather than being in conflict, the criterion of fruits complements the understanding of natural law by providing a practical means of evaluating the long-term moral implications of actions.

Reply to Objection 2. Aristotle's emphasis on virtuous acts as ends in themselves does not preclude the evaluation of actions based on their outcomes. Indeed, Aristotle also recognizes the importance of the consequences of actions in determining their moral quality. The good life, or eudaimonia, is achieved not only through virtuous acts but also through the good that these acts bring about in the life of the individual and the community. Thus, the principle of judging by fruits can be seen as an extension of Aristotelian ethics, evaluating not just the act itself but its contribution to the ultimate end of human flourishing.

Article 3. Whether the teaching of Jesus on judging by fruits fundamentally contrasts with the Aristotelian concept of natural law, or whether my harmonization attempts overlook the practical essence of His instruction?

Objection 1. It appears that Jesus' teaching directly challenges the Aristotelian natural law tradition, which I uphold. By focusing on the tangible outcomes or "fruits" of actions for moral discernment, Jesus seems to advocate for a more empirical and less abstract method of ethical evaluation, unlike the a priori moral absolutes proposed by natural law theory.

Objection 2. Furthermore, the insistence on evaluating the "fruits" in the moral order might seem like a sophistic maneuver to reconcile irreconcilable approaches to ethics. Jesus' straightforward criterion for moral discernment seems to be at odds with the complex, often abstract, principles of natural law, suggesting a genuine conflict between the two.

On the contrary, the teaching of Jesus on judging by fruits does not negate the principles of natural law but rather complements them by providing a practical method for discernment in the ethical and spiritual domains. His teaching emphasizes the observable manifestations of moral and spiritual principles in the world, thereby underscoring the importance of concrete evidence of goodness or evil in our lives and teachings.

I answer that, my previous attempt to harmonize these teachings may have indeed overemphasized the theoretical coherence at the expense of recognizing the distinct emphasis Jesus places on practical discernment in ethics. Jesus' teaching on judging by fruits aims to provide a clear, accessible criterion for evaluating the moral quality of actions and teachings, focusing on their actual impact on individuals and communities. This approach does not discard the principles of natural law but rather invites a more immediate, experiential engagement with ethical discernment.

Natural law provides a foundation for understanding the inherent moral dimensions of human actions based on their alignment with human nature and ultimate ends. Jesus' emphasis on fruits, however, directs attention to the practical implications of these actions, encouraging a form of ethical reflection that is both accessible and immediately relevant to daily life. This does not necessarily introduce an opposition to natural law but rather a complementary perspective that enhances our ability to discern good from evil in a concrete, tangible manner.

Reply to Objection 1. While Jesus' teaching may seem to diverge from the abstract principles of natural law, it does not fundamentally oppose them. Instead, it offers a practical means of applying these principles by evaluating the real-world outcomes of actions and teachings. This approach democratizes ethical discernment, making it accessible to all, regardless of their philosophical training.

Reply to Objection 2. The term "fruits in the moral order" was indeed an attempt to bridge two seemingly distinct ethical approaches. However, acknowledging the practical focus of Jesus' teaching does not diminish the value of natural law but rather highlights the importance of applying its principles in a way that directly impacts human well-being and spiritual growth. Jesus' criterion of fruits serves as a vital, practical tool for ethical evaluation, rooted in the observable realities of life.

In conclusion, while Jesus' teaching and the Aristotelian concept of natural law may emphasize different aspects of ethical discernment, they are not inherently contradictory. Instead, they can be viewed as offering complementary perspectives that, together, provide a fuller understanding of how to discern and pursue the good in our lives.

Article 4. Whether there is a contradiction in asserting that violating natural law is wrong even if it appears to bear good fruits?

Objection 1. It seems there is indeed a contradiction in my previous assertions. If judging by fruits is a valid criterion for discerning good from evil, as Jesus teaches, then it follows that actions which bear good fruits cannot be deemed intrinsically evil, even if they appear to violate natural law principles.

Objection 2. Furthermore, if natural law dictates that certain actions are wrong in themselves, regardless of their outcomes, this seems to directly conflict with the notion that the moral quality of an action can be discerned through its fruits. This implies a fundamental inconsistency in attempting to reconcile these two approaches.

On the contrary, the essence of natural law, as articulated in my works, hinges on the alignment of human actions with their ultimate ends and purposes as ordained by God. This alignment ensures the good of the individual and the common good, which is the ultimate "fruit" of adhering to natural law. Thus, the apparent contradiction arises from a misunderstanding of what constitutes "good fruits" in a moral sense.

I answer that, my previous attempts to harmonize these teachings may have inadequately addressed the tension between the empirical assessment of moral actions through their fruits and the principled assessment of actions based on their inherent nature as per natural law. This tension, however, can be resolved by clarifying the nature of "good fruits" within a moral context.

Good fruits, in the fullest moral sense, are not merely immediate or superficial outcomes that appear beneficial. Rather, they are the deeper, long-term consequences of actions that truly contribute to the flourishing of human nature and the realization of the common good. From this perspective, actions that violate natural law, despite appearing to produce immediate beneficial outcomes, ultimately lead to harm or disorder in the moral and spiritual realms, thus bearing bad fruits in the comprehensive evaluation of their consequences.

Reply to Objection 1. The criterion of fruits, as taught by Jesus, must be understood in the context of a holistic moral vision that considers the ultimate ends of human actions. Actions that violate natural law principles, even if they seem to produce beneficial outcomes in the short term, are misaligned with the true good of human beings and the order of creation, and therefore, in the fullness of time, produce bad fruits.

Reply to Objection 2. The perceived contradiction is resolved by recognizing that the assessment of fruits involves more than immediate outcomes; it encompasses a consideration of the long-term alignment of actions with the truth of human nature and the common good. Thus, there is no fundamental inconsistency in asserting that actions violating natural law are wrong, as such actions, when fully understood in their consequences, do not truly bear good fruits.

In conclusion, while there may appear to be a contradiction between judging actions by their fruits and assessing them based on natural law, a deeper understanding of what constitutes "good fruits" in a moral sense reveals a harmonious integration of these approaches. Actions aligned with natural law ultimately bear good fruits in the fullest sense, contributing to the true flourishing of human beings and the realization of the common good.

Article 5. Whether it is sufficient for a Christian to orient themselves solely by the rule of thumb given by Jesus, without giving any thought to the Aristotelian concept of natural law?

Objection 1. It seems that for a Christian, adhering solely to the rule of thumb given by Jesus to judge by their fruits should be sufficient. The teachings of Jesus are direct and accessible, offering a clear and immediate criterion for moral discernment that does not require the complex understanding of natural law.

Objection 2. Moreover, since the ultimate goal of Christian life is to follow Christ, prioritizing His teachings over philosophical systems like that of Aristotle's natural law appears more fitting. As the Apostle Paul says, "For I determined not to know anything among you, save Jesus Christ, and him crucified" (1 Corinthians 2:2). This suggests a precedence of Christ's teachings over philosophical knowledge.

On the contrary, the teachings of Christ and the principles of natural law are not mutually exclusive but are complementary in guiding moral and ethical conduct. While the teachings of Jesus provide the fundamental spiritual and moral framework for Christians, natural law offers philosophical grounding that helps articulate and understand the moral order inherent in creation, which is also affirmed by Christian doctrine.

I answer that, the simplicity and immediacy of Jesus' teaching on judging by fruits provide a practical and accessible criterion for moral discernment that is essential for daily Christian living. However, this does not negate the value of engaging with the concept of natural law, which elaborates on the reasons why certain actions are inherently ordered towards the good or away from it, according to human nature as created by God.

Natural law serves to deepen our understanding of the moral principles embedded in the fabric of creation and human nature itself, principles which are also affirmed by the teachings of Christ and Scripture. It provides a philosophical basis for understanding why certain actions bear good fruits and others do not, reflecting the wisdom and order of the Creator. This deeper understanding can enrich a Christian's moral reasoning and spiritual reflection, aiding in the application of Christ's teachings in complex or challenging situations.

Reply to Objection 1. While the teachings of Jesus are indeed sufficient for salvation and moral guidance, engaging with natural law does not replace or diminish the teachings of Christ but rather enhances and supports a fuller understanding of them. It is a tool for deepening one's comprehension of the moral order that Christ came to fulfill and perfect, not to abolish.

Reply to Objection 2. Prioritizing the teachings of Christ is indeed central to Christian life. However, engaging with natural law is not a matter of placing philosophical knowledge over Christ's teachings but of seeking a deeper understanding of the truths to which Christ's teachings point. As St. Paul engaged with the philosophical ideas of his time to elucidate and spread the Gospel, so too can Christians engage with natural law to better articulate and live out the moral truths revealed by Christ.

In conclusion, while the rule of thumb given by Jesus is indeed sufficient for guiding moral conduct, the engagement with natural law enriches a Christian's understanding of the moral order and supports a deeper and more reasoned approach to applying Christ's teachings in their lives.

Article 6. Whether accepting the natural law criterion for morality introduces an epistemological problem by necessitating a separate article of faith, not directly grounded in the Gospels?

Objection 1. It appears that integrating the concept of natural law into Christian morality indeed introduces an epistemological problem. If this concept is not explicitly found in the Gospels and requires adherence to philosophical notions external to the direct teachings of Jesus, it seems to impose an additional belief system upon the Christian faith.

Objection 2. Furthermore, by suggesting that the criteria of natural law and the fruits criterion coincide, one is required to make a leap of faith beyond what is scripturally warranted. This could be seen as adding to the teachings of Christ, contrary to the scriptural admonition not to add to or take away from the Word (Deuteronomy 4:2; Revelation 22:18-19).

On the contrary, the use of natural law in Christian ethics does not constitute a separate article of faith but rather a philosophical framework that helps articulate the moral intuitions and teachings already present within the Christian tradition. The Church Fathers and later Christian thinkers have long engaged with philosophical ideas to elucidate and defend the truths of faith, demonstrating that reason and faith are complementary rather than contradictory.

I answer that, the engagement with natural law in the context of Christian morality does not necessitate an additional act of faith but rather an act of reason that seeks to understand and articulate the moral order inherent in God's creation. The concept of natural law seeks to identify the principles of morality accessible to human reason, principles that reflect the Creator's design and thus are not in contradiction with, but rather supportive of, the moral teachings found in the Gospels.

The criterion of fruits, as taught by Jesus, and the principles of natural law, understood through philosophical reflection, both point towards the same moral truths: that good actions lead to the flourishing of the individual and the community, and that there is an objective moral order to which human beings are called to conform their lives. The integration of natural law into Christian ethics is not an imposition of an external belief system but an endeavor to more fully comprehend and articulate the moral wisdom that is compatible with, and indeed underlies, the teachings of Christ.

Reply to Objection 1. While natural law as a philosophical concept is not explicitly detailed in the Gospels, the moral order it describes is consistent with the created order to which Scripture attests. Engaging with natural law is thus not a matter of adopting a separate article of faith but of employing reason to more deeply understand the moral implications of being created in the image of God and living in a world governed by His laws.

Reply to Objection 2. Acknowledging the harmony between the fruits criterion and the principles of natural law does not add to the teachings of Christ but rather provides a rational foundation for understanding and applying these teachings. It is an act of reason, guided by faith, that recognizes the coherence between the moral intuitions accessible to human reason and the moral revelations given by God through Scripture.

In conclusion, the acceptance of natural law as a criterion for morality does not introduce an epistemological problem or a separate article of faith but is a rational endeavor to articulate the moral order evident in creation, which is fully compatible with and enriches our understanding of the moral teachings of Jesus Christ.

Article 7. Whether accepting Aristotle's interpretation of natural law requires a separate act of faith, distinct from the acceptance of natural law as coinciding with God's plan.

Objection 1. It seems that accepting Aristotle's interpretation of natural law does indeed require a separate act of faith. Since Aristotle's conclusions about natural law are based on his own observations and rational deductions about nature, which may not align with the fuller understanding of creation revealed in Scripture and developed in Christian thought, adhering to his specific views necessitates an additional belief not directly supported by divine revelation.

Objection 2. Moreover, given the advancements in our understanding of the natural world, many of Aristotle's specific assertions about nature and, by extension, natural law, are outdated or have been contradicted by subsequent discoveries. Thus, holding to Aristotle's specific views on natural law could seem to require disregarding more accurate, contemporary understandings of the natural world, which could be seen as an unnecessary act of faith in his philosophical system.

On the contrary, the acceptance of natural law in the Christian tradition is not uncritically tied to Aristotle's specific interpretations but is rather a recognition of the existence of a moral order embedded in creation by God. This moral order is accessible to human reason and reflects God's plan for humanity. The engagement with Aristotle's thought, or that of any philosopher, is an exercise in reason that seeks to understand and articulate aspects of this moral order, not an act of faith in the philosopher's system per se.

I answer that, the distinction between accepting the concept of natural law as part of God's creation and accepting Aristotle's specific interpretations of natural law is crucial. Natural law, as understood within the Christian tradition, posits that there are objective moral truths grounded in the very nature of humanity and the world, which are consistent with God's plan and thus accessible to human reason. This understanding does not depend on any one philosopher's interpretation but is derived from the broader recognition of a moral order that governs creation.

Aristotle's contributions to the concept of natural law are valuable insofar as they offer insights into the ways in which human beings might live in accordance with their nature and achieve their ultimate end. However, his specific conclusions are not articles of faith but subjects of philosophical inquiry and debate. They are evaluated and integrated into Christian thought to the extent that they align with the revealed truths of Christianity and the observed realities of the natural world.

Reply to Objection 1. Accepting Aristotle's specific views on natural law does not require a separate act of faith but rather an act of reason that critically engages with his philosophical insights. This engagement is guided by the light of faith and the teachings of the Church, discerning which aspects of his thought are compatible with Christian doctrine and which may need to be revised or abandoned in light of further revelation or understanding.

Reply to Objection 2. The development of our understanding of the natural world invites a reevaluation of Aristotle's specific claims about nature and natural law. This process does not reflect a faith in Aristotle's infallibility but rather a commitment to seeking truth, wherever it may be found, and integrating it into a coherent understanding of God's plan for humanity. It involves an ongoing dialogue between faith and reason, where Aristotle's insights are appreciated but not accepted uncritically.

In conclusion, while Aristotle's exploration of natural law offers valuable insights into the moral order, accepting his specific interpretations is not a matter of faith but of reasoned inquiry. This inquiry is always conducted in the light of Christian faith, which discerns and integrates whatever is true and good in philosophical thought into the fuller understanding of God's plan revealed in Scripture and Tradition.

Article 8. Whether the discovery of homosexuality as an inherent part of biological nature invalidates natural law arguments against homosexuality derived from Aristotelian thought?

Objection 1. It seems that the discovery of homosexuality as an inherent biological trait does invalidate natural law arguments against homosexuality based on Aristotelian thought. If Aristotle's understanding of natural law relies on an incomplete or incorrect view of nature, then conclusions drawn from this understanding, including those related to homosexuality, must be reconsidered in light of new empirical evidence.

Objection 2. Furthermore, if natural law is understood to be a reflection of the moral order embedded in the physical and biological realities created by God, then the presence of homosexuality across various species, including humans, would suggest that it is part of the natural diversity intended by God. Thus, any natural law argument against homosexuality that fails to recognize this diversity seems fundamentally flawed.

On the contrary, the Christian understanding of natural law encompasses more than the biological aspects of human existence, extending to the moral and spiritual dimensions of human acts. While Aristotle's natural philosophy forms a part of the historical foundation for natural law theory, the Christian tradition has developed and nuanced this theory to consider the fullness of human nature, created in the image and likeness of God, which includes but is not limited to biological considerations.

I answer that, the presence of homosexuality in human populations and other species is a complex phenomenon that challenges simplistic interpretations of natural law. The Christian understanding of natural law is not limited to biological or reproductive functions but encompasses the entirety of human nature, including the rational soul, free will, and the capacity for relational love. Thus, while empirical findings about the natural world can inform our understanding of natural law, they do not automatically invalidate moral principles derived from a more comprehensive understanding of human nature and purpose.

It is crucial to distinguish between descriptive observations of nature, which include the occurrence of homosexual behavior in various species, and prescriptive moral norms, which are derived from a philosophical and theological reflection on the purposes and ends of human life as understood in Christian anthropology. This reflection considers not only biological aspects but also the spiritual, rational, and relational dimensions of human existence.

Reply to Objection 1. The reconsideration of natural law arguments in light of new empirical evidence is a necessary and ongoing process. However, this does not mean that every discovery about biological nature automatically invalidates established moral principles. Instead, it invites a deeper inquiry into the relationship between biological traits and the moral law, which is oriented toward the flourishing of the whole person, including their spiritual and moral dimensions.

Reply to Objection 2. Recognizing the biological reality of homosexuality does not by itself resolve the moral questions associated with human sexual behavior. The moral evaluation of human acts according to natural law theory involves considerations of the rational and spiritual purposes of human life, including how sexual acts fit within the context of the human vocation to love and communion. This evaluation is informed by, but not reducible to, biological considerations.

In conclusion, while the discovery of homosexuality as an inherent part of biological nature presents important considerations for natural law theory, it does not automatically invalidate the moral reflections based on a comprehensive understanding of human nature and purpose. The challenge lies in integrating empirical findings with philosophical and theological reflections on the fullness of human existence in a way that respects the dignity of every person and promotes the true flourishing of all.

Article 9. Whether the presence of homosexual subpopulations throughout creation suggests a reevaluation of the primary function of human sexuality from the perspective of natural law and divine intent?

Objection 1. It seems inappropriate to challenge the traditional natural law perspective on the primary function of human sexuality based on the observation of homosexual subpopulations in nature. This could imply a misunderstanding of divine providence and the complexity of natural law, which encompasses but is not limited to procreation.

Objection 2. Moreover, to assert that procreation is not the primary function of human sexuality based on current observations might neglect the broader theological and philosophical teachings on the purpose and nature of human sexuality, which have been developed over centuries.

On the contrary, the observation that God has created a natural world in which homosexual behaviors and subpopulations exist across various species, including humans, invites a thoughtful reflection on the purposes of human sexuality beyond procreation. This does not dismiss God's decisions but rather seeks a deeper understanding of them, acknowledging the richness and complexity of creation.

I answer that, the presence of homosexual subpopulations throughout creation indeed suggests a need for a broader understanding of the purposes of human sexuality within the natural law framework. While the traditional view emphasizes procreation as a primary purpose, the observation of natural diversity indicates that the relational and unitive aspects of sexuality also hold significant value in God's creation.

This perspective does not dismiss the importance of procreation but rather acknowledges that human sexuality serves multiple ends, including the fostering of intimate bonds, mutual support, and love between persons. Such a view is consistent with a holistic understanding of natural law, which considers the fullness of human flourishing, encompassing physical, emotional, relational, and spiritual dimensions.

Reply to Objection 1. Recognizing the complexity of creation and the variety of ways in which love and relationality are manifested does not challenge divine providence but rather reflects an openness to the breadth of God's design. This approach seeks to understand the intrinsic value and dignity of all individuals, as well as the diverse ways in which human beings can live out their call to love.

Reply to Objection 2. While it is true that theological and philosophical teachings on human sexuality have developed over centuries, these teachings are not static but are subject to deepening understanding as we grow in our knowledge of God's creation. The engagement with new insights from the natural world, including the existence of homosexual subpopulations, can enrich our understanding of the divine plan for human sexuality and relationships.

In conclusion, the presence of homosexual subpopulations in nature calls for a nuanced understanding of human sexuality that recognizes both its procreative and unitive dimensions. This approach does not undermine the significance of procreation but rather affirms that the purposes of human sexuality, as intended by God, extend to the nurturing of deep, loving relationships. This understanding invites us to reflect on the moral rules derived from nature's design with a broader perspective, considering the full scope of human flourishing as envisaged by the Creator.

Article 10. Whether Aristotle's interpretation of natural law should be reconsidered in light of contemporary biological knowledge, implying a re-derivation of its specific conclusions?

Objection 1. It seems unnecessary to reconsider Aristotle's interpretation of natural law because the principles he articulated are based on more than just the biological knowledge of his time. They are grounded in a philosophical understanding of being, purpose, and the good, which transcends specific empirical findings.

Objection 2. Furthermore, to claim that Aristotle's interpretation of natural law is simply wrong because it does not account for contemporary biological knowledge could imply that the truth about natural law is subject to change based on current scientific understanding, which would undermine its objective and universal nature.

On the contrary, the principle of natural law suggests that moral truths can be discerned through reason by observing nature and human nature. If contemporary biological knowledge presents a more accurate understanding of nature, including human sexuality and the existence of homosexual subpopulations, then it follows that our interpretation of natural law should be informed by this knowledge to remain true to its foundational principle.

I answer that, while Aristotle's contributions to the understanding of natural law provide a valuable foundation, the essence of natural law theory is the pursuit of the good as determined by the nature and ends of beings, especially human beings. Given that our understanding of nature, including human biology and psychology, has advanced significantly since Aristotle's time, it is reasonable to suggest that the specific conclusions drawn from natural law should be revisited and potentially revised in light of contemporary knowledge.

This does not mean that Aristotle's entire framework is obsolete or that the core principles of natural law—such as the pursuit of the good, the importance of virtue, and the natural ends of human beings—are wrong. Instead, it acknowledges that the application of these principles must be informed by the best available understanding of human nature, which now includes insights from modern biology, psychology, and other sciences.

Reply to Objection 1. While Aristotle's philosophical insights transcend his empirical observations, the application of natural law to specific moral questions must be informed by accurate and comprehensive knowledge of nature. This does not diminish the value of his philosophical contributions but rather calls for their integration with contemporary scientific understanding.

Reply to Objection 2. Revisiting specific conclusions of natural law in light of new knowledge does not undermine the objective and universal nature of natural law but demonstrates a commitment to truth and the proper alignment of our moral reasoning with the reality of creation as we come to understand it more fully. The objective nature of natural law is not compromised by a deepened understanding of nature; rather, it is affirmed through a more accurate application of its principles.

In conclusion, the re-derivation of specific conclusions from natural law in light of contemporary biological knowledge is not a rejection of the tradition but an essential part of its ongoing development. This process allows for a more accurate and comprehensive application of natural law principles to moral questions, ensuring that our ethical reasoning remains grounded in the true nature and ends of human beings as revealed through both reason and faith.

Article 11. Whether there are arguments against homosexuality in Christian theology independent of the traditional concept of natural law and Aristotle's philosophy?

Objection 1. It might seem that without relying on Aristotle's interpretation of natural law, Christian theology lacks a basis to argue against homosexuality. If the argument against homosexuality is not grounded in an outdated understanding of natural biology, then perhaps there is no theological basis for such a stance.

Objection 2. Furthermore, if the traditional concept of natural law is reconsidered in light of contemporary understandings of human sexuality, including the natural occurrence of homosexuality across species, it could be argued that Christian objections to homosexuality must also be reevaluated, suggesting a potential shift in theological perspective.

On the contrary, Christian theology's stance on homosexuality is not solely based on Aristotelian natural law or biological considerations. It also draws from scriptural references, the teachings of the Church Fathers, and the magisterial teachings of the Church, which consider the moral, relational, and spiritual dimensions of human sexuality.

I answer that, the Christian understanding of human sexuality and the moral evaluation of homosexual acts involve a comprehensive framework that includes scriptural teachings, the tradition of the Church, and the moral law as understood through both natural law and divine revelation. This framework considers the purpose of human sexuality within the context of marital love, procreation, and the unitive dimension of the sexual act as reflecting the covenantal love of God.

Reply to Objection 1. Christian theology does not solely rely on Aristotle or a specific interpretation of natural law to discuss the morality of homosexuality. The scriptural passages in both the Old and New Testaments address sexual behavior, including homosexual acts, within the context of God's law and the moral order (e.g., Leviticus 18:22, Romans 1:26-27, 1 Corinthians 6:9-10). These teachings are part of a broader moral and theological context that considers the purpose and ends of human sexuality.

Reply to Objection 2. The reevaluation of traditional concepts in light of contemporary knowledge does not automatically negate the scriptural and magisterial teachings of the Church on the nature of marriage and sexual morality. The Church's understanding of the moral dimensions of sexuality is not based solely on biological considerations but on a holistic view of the person created in the image of God and called to a specific vocation of love and communion.

In conclusion, while Aristotelian natural law has historically informed Christian ethical reasoning, the theological evaluation of homosexuality in Christianity is rooted in a broader context that includes scriptural teachings, the living tradition of the Church, and the understanding of the human person and human sexuality as revealed in divine revelation. This comprehensive approach allows for a moral discourse that is responsive to new understandings of human nature while remaining faithful to the core principles of Christian anthropology and morality.

Article 12. Whether Christian theology should be cleared of Aristotelian natural law influences to rewrite arguments against homosexuality in a manner that is purely Christian, considering contemporary scientific understanding.

Objection 1. It seems unnecessary to remove the influence of Aristotelian natural law from Christian theology because the integration of philosophy and theology has historically enriched the Christian intellectual tradition. This synthesis has helped articulate complex theological concepts in a rigorous and reasoned manner, aiding the faithful in understanding the faith more deeply.

Objection 2. Moreover, to attempt to rewrite Christian arguments against homosexuality without any philosophical underpinning, including that of natural law, risks reducing the theological discourse to a series of biblicist interpretations that may fail to engage adequately with the complexities of human nature and ethical reasoning.

On the contrary, given the advancements in contemporary science that challenge previous understandings of human sexuality, there is a call within Christian theology to reexamine the arguments related to homosexuality in light of this new knowledge. This reexamination would ensure that theological discourse remains relevant and responsive to the lived realities of people today, while still being grounded in the core teachings and values of the Christian faith.

I answer that, while the Aristotelian concept of natural law has significantly influenced Christian ethical reasoning, including discussions on human sexuality, the essence of Christian theology is its foundation on divine revelation as transmitted through Scripture and Tradition. This foundation provides a rich resource for moral and theological reflection that is capable of engaging with contemporary questions, including those related to human sexuality.

The task of theology is to articulate the faith in every age, responding to new challenges and questions with the timeless truths of the Gospel. In doing so, theology draws upon the resources of philosophy, science, and human experience to deepen our understanding of these truths and their implications for contemporary life. Therefore, reevaluating the arguments related to homosexuality in a manner that is faithful to Christian teachings, while also engaging with contemporary scientific understanding, does not require discarding the philosophical tradition entirely. Instead, it invites a critical and discerning engagement with this tradition, seeking ways to integrate philosophical insights with contemporary knowledge in a manner that enriches theological discourse.

Reply to Objection 1. The historical integration of philosophy and theology in Christian thought does not preclude the possibility of reevaluating certain philosophical influences, including those of Aristotle, in light of new knowledge and understanding. Such reevaluation is part of the ongoing development of theological thought, which seeks to articulate the faith in ways that speak meaningfully to each generation.

Reply to Objection 2. Engaging with contemporary scientific understandings of human sexuality does not necessitate abandoning philosophical reasoning or reducing theological discourse to simplistic interpretations. Rather, it challenges theology to find new ways to integrate science, philosophy, and theology in a coherent and faithful synthesis that addresses the complexities of human life and sexuality.

In conclusion, while Aristotelian natural law has contributed to Christian ethical reasoning, the contemporary challenge regarding homosexuality invites a thoughtful and informed reevaluation of theological arguments. This process respects the integrity of Christian teaching while also engaging with contemporary scientific insights, ensuring that the Church's moral guidance is both faithful to divine revelation and relevant to the lives of people today.

Article 13. Whether a convincing case against homosexuality can be built from biblical references and how this relates to modern insights into human sexuality and natural law.

Objection 1. It seems challenging to build a convincing case against homosexuality based solely on the few biblical references that address it negatively, especially when considering the broader biblical narrative's emphasis on love, compassion, and justice. This focus appears to contradict a rigid stance against homosexuality, especially in light of contemporary understandings of human sexuality.

Objection 2. Moreover, if modern natural law insights suggest that homosexuality might indicate that procreation is not the sole essence of human sexuality, then adhering strictly to those few biblical passages without considering the broader context of biblical teaching and contemporary knowledge seems to be an inadequate approach to moral theology.

On the contrary, the task of Christian theology is not merely to build cases for or against specific acts based on isolated scriptural texts but to interpret these texts within the whole context of divine revelation and the living Tradition of the Church. This approach involves a discerning engagement with Scripture, Tradition, and the signs of the times, including contemporary understandings of human sexuality.

I answer that, constructing a theological or moral stance on any issue, including homosexuality, requires a holistic approach that considers Scripture in its entirety, the Tradition of the Church, and rational reflection informed by natural law and human sciences. The few biblical passages that explicitly mention homosexuality must be understood within the larger biblical themes of covenant, love, fidelity, sin, and redemption.

The modern insights into human sexuality, including the understanding that sexual orientation may not be a simple choice or merely a deviant behavior, challenge us to deepen our reflection on what it means to be created in the image of God and how to live in authentic relationships that reflect God's love. This does not necessarily negate the moral teachings derived from Scripture and Tradition but invites a more nuanced understanding of these teachings in light of contemporary knowledge.

Reply to Objection 1. The biblical narrative's overarching themes of love, compassion, and justice indeed provide a critical context for interpreting specific passages. The call to love one's neighbor, to seek justice, and to walk humbly with God (Micah 6:8) must inform our understanding of morality, including issues related to sexuality. This approach does not dismiss the moral dimensions of sexuality but rather frames them within God's desire for human flourishing and relational integrity.

Reply to Objection 2. The insights from modern natural law and the human sciences regarding homosexuality and the multifaceted nature of human sexuality do not automatically invalidate traditional moral teachings. Instead, they provide an opportunity for these teachings to be reexamined and articulated in ways that are both faithful to the Christian understanding of the human person and responsive to the genuine experiences and challenges faced by individuals today.

In conclusion, while Scripture contains passages that have traditionally been interpreted as condemning homosexuality, a convincing theological case on any moral issue requires a comprehensive approach that considers the entirety of Scripture, the Tradition of the Church, and the insights of reason and contemporary knowledge. This process aims to uphold the dignity of every person, promote genuine human flourishing, and reflect the depth of God's love for all creation.

The current theological debate on homosexuality within Christianity mirrors the complexity and diversity of perspectives found across various denominations, reflecting deep theological, ethical, and interpretive divides. This debate is not only about interpreting specific biblical passages but also involves broader questions about the nature of marriage, human sexuality, and the church's mission in the world.

For example, the Reformed Church in America (RCA) has faced significant internal division over LGBTQ ordination and same-sex marriage, leading to structural reorganizations and the formation of new church networks that align more closely with conservative or progressive values. This indicates an ongoing struggle within denominations to reconcile differing views on sexuality while attempting to maintain unity and fidelity to their theological convictions​​.

Similarly, the Anglican Communion exhibits a wide range of positions on homosexuality, from the Church of England's cautious stance that allows for same-sex partnerships for laypersons and celibate gay clergy, to more progressive policies in the Episcopal Church in the USA and other Anglican provinces that have embraced LGBTQ inclusion to various degrees. This diversity reflects the broader tensions within global Anglicanism between maintaining traditional doctrinal stances and adapting to changing social and cultural contexts​​.

These examples illustrate that the debate on homosexuality in Christian theology is not solely reliant on Aristotelian natural law or any single theological framework but is deeply embedded in the interpretive, historical, and cultural dynamics of each denomination. The discussions are ongoing, with denominations and congregations continually wrestling with how best to interpret scripture, tradition, and the signs of the times in light of the Gospel's call to love and justice.
