Moral relativism—the idea that truth and morality are matters of personal opinion or cultural agreement—is fundamentally incompatible with the Christian worldview, which is based on the premise that God's moral law is absolute, eternal, and objective (Psalm 33:4). Christians should respond to relativism publicly with gentle, respectful dialogue (1 Peter 3:15), exposing its logical inconsistencies, and demonstrating the superior, life-giving fruit of absolute truth found in Jesus Christ.  

A Christian must affirm objective morality, meaning certain actions are inherently right or wrong, regardless of opinion. This standard is rooted not in cultural views but in the unchanging character of a holy God (Psalm 145:17). Subjective morality fails to account for the universal human conscience (Romans 2:14–15) and undermines universal human rights. The Christian's call is to pursue holiness by conforming their lives to this fixed, objective truth (1 Peter 1:15–16).
