A potentially difficult text for today’s Christians, The Ethics of Sex gives a fascinating insight into the mindset of how a Christian thinker considered gender and sexuality when the definitions of both were becoming more and more fluid. Caught between the points of the harsh restrictions of the Third Reich, and the revolutionary approach popularised in the 1960s, Thielicke offers a modern reader the opportunity to understand more of this pivotal period in history. In The Ethics of Sex, Thielicke confronts hot-button issues, many of which are still controversial today, like abortion, homosexuality and artificial insemination. Here he forges a path for the Christian philosopher that is consistent with Christian values of compassion and understanding. While a complex text, The Ethics of Sex rewards both the scholar and the historian.
