This edition is once again a new, thoroughly revised version of Christian Ethics II. In some portions the subject matter has been reorganized more organically, and recent theological developments and documents of the magisterium have been integrated. New themes have been added, others further developed, such as deepening the concept and content of mission, as well as ecumenical participation. Also, questions in bioethics have been supplemented, such as the duty to preserve life, topics of prenatal medicine, reproductive and therapeutic cloning, genetic alteration, and euthanasia. Other issues raised concern the discrimination against women, civil marriage of homosexuals, compassion in prison care, the right of asylum, humanitarian interventions, the fostering of peace after conflicts, empowerment of the poor in development projects, and the treatment of animals. The author hopes that this new edition will be a contribution to the ongoing aggiornamento of moral theology and that it will continue to meet the expectations of its readers.
