Proof texts work when the moral intuitions of the culture track with the broad shape of biblical teaching. That is no longer the case. Further, advances in technology now raise all kinds of questions about what it even means to be human—which in turn raises questions not only about fertility, but about other issues, from end-of-life care to the use of AI. The broader biblical account of human nature, not isolated proof texts, must now factor into Christian discussions of the most pressing ethical issues that we face.
Carl Trueman wrote a timely article over at First Things. He addresses the shifting cultural landscape and its impact on Christian ethics, especially around issues like abortion, IVF, and contraception. He argues that the acceptance of practices born from the sexual revolution reflects a growing societal belief in personal autonomy and happiness. Pragmatism. The church, once aligned with broader cultural values, now faces opposition as these values have diverged. He goes further. He says that Protestant churches must now take on the challenge of teaching Christian ethics more intentionally, particularly on complex bioethical issues, since societal support no longer exists.
Trueman critiques the Protestant reliance on proof texts, calling for a deeper understanding of biblical anthropology to address modern ethical challenges. He notes that the pragmatic, results-oriented mindset of wider culture has seeped into evangelical circles, influencing views on IVF and other moral questions. In response, churches need to develop distinct moral communities that both understand and live out Christian ethics in opposition to secular norms.
Finally, Trueman calls for a new generation of Protestant ethicists to engage with these pressing issues, grounded in a Christian understanding of human nature. The church, he argues, must rise to the task of shaping moral intuitions through robust teaching and discipleship.
