A critical exploration of the foundations and applications of Christian moral theology, from biblical ethical principles and natural law theory to contemporary issues in bioethics, social justice, and environmental stewardship. Examines how faith traditions inform ethical decision-making.

"You shall love the Lord your God with all your heart and with all your soul and with all your mind... And a second is like it: You shall love your neighbor as yourself."

— Matthew 22:37–39 (ESV) — The Great Commandment

Foundations of Christian Moral Theology

Christian ethics begins with the conviction that moral truth is grounded in the character of God as revealed in Scripture and in the created order. The natural law tradition, developed by Augustine and systematized by Thomas Aquinas, holds that human reason can discern enduring moral norms inscribed in human nature by the Creator.

Protestant traditions have emphasized the priority of Scripture over natural law and the role of the Holy Spirit in guiding the moral lives of believers. Reformed ethics has foregrounded the covenant as the framework within which moral obligations are understood — obligations flowing from God's redemptive grace rather than from human effort to earn favor.
