The book "Foundations of Ethics" by Eberhard Schockenhoff offers a comprehensive analysis of theological ethics, which has been shaped by intense controversies in recent decades. It highlights the challenges arising from the tension between different foundations of norms and faith references. Schockenhoff examines the self-understanding of Christianity in the context of modern culture and reflects on the relevance of its message in light of future moral questions. This revised edition represents the first coherent presentation of the foundational issues of theological ethics in a long time and is thus a significant contribution to philosophical and religious discourse.
