Who decides what is morally right—God or people?
QUESTION:
Who decides what is morally right—God or people (like: Thomas Aquinas)—and why do Christians sometimes disagree about what is moral, especially when reading passages like Judges 11?
ANSWER:
When people ask whether morality is defined by man or by God, they often assume that morality is a universal system that applies the same way in every age, covenant, and dispensation. But Scripture shows something far more precise. God Himself defines what is right, but He does so within the framework of His revealed will for each people and each program. What was moral for Israel under the law is not the same as what governs the Body of Christ under grace. This is why trying to force all morality into one timeless category leads to confusion, disagreement, and contradictions.
The word “moral” simply refers to what is right or wrong according to a standard. The real question is not what the word means, but whose standard applies. Thomas Aquinas and other theologians tried to build universal systems of morality by blending philosophy with Scripture, but the Bible never asks Christians to follow man‑made categories or philosophical ethics. God revealed His will to Israel through the law, and He reveals His will to the Body of Christ through grace. Both come from Him, but they are not the same system, and they are not given to the same people.
