Christian ethics
Multi-faceted ethical system rooted in biblical and natural law traditions.
Christian ethics, also known as moral theology, is a multi-faceted ethical system that combines virtue ethics, deontological ethics, natural law ethics, and prophetic ethics. It derives its metaphysical core from the Bible, viewing God as the ultimate source of all power, and applies to all areas of personal and societal ethics. Originating in early Christianity from c. 27 to 325 AD, it continued to develop through the Middle Ages, the Reformation, and the counter-Reformation, eventually separating from theology during the eighteenth and nineteenth centuries to become a discipline between theology and the social sciences.

Lore & Background
Christian ethics began during the early Christian period, from the ministry of Jesus (c. 27 AD–30) to the First Council of Nicaea in 325. It emerged from Jewish and Christian heritage, depending on the Hebrew canon and Greek and Hellenistic philosophy. The Council of Jerusalem (c. 50 AD) issued decrees on abstaining from blood, sexual immorality, meat sacrificed to idols, and strangled animals, which were binding for centuries and are still observed by the Greek Orthodox Church. Early Christian writings addressed moral instruction on specific problems in the hostile Roman social setting, including the role of women, sexuality, and slavery.
Reader's Guide
Christian ethics has had a significant and lasting impact on Western moral thought, shaping both personal conduct and societal norms. Its combination of virtue ethics, deontological duty, natural law, and prophetic social critique provides a comprehensive framework that has been debated and reinterpreted across centuries. The variety of ethical perspectives in the Bible has led to perennial disagreement over at least seven major principles, with Christian ethicists using reason, philosophy, natural law, social sciences, and the Bible to formulate modern interpretations. The Reformation and counter-Reformation heavily impacted its political and economic teachings, while movements such as the social Gospel and liberation theology represent prophetic ethics that challenge other theories by focusing on social justice and group sin. For most 21st-century scholars, Christian ethics fits between theology and the social sciences, reflecting its evolution from a branch of theology to a distinct discipline.
