means The view that an act is morally right or wrong simply because God commands or forbids it, rather than God commanding it because it's independently right or wrong.

from The idea is ancient — Plato's dialogue Euthyphro (c. 4th century BCE) already stages the core puzzle by asking whether something is holy because the gods love it, or the gods love it because it's holy. The phrase 'divine command theory' itself is a modern philosophical label, used by scholars analyzing ethical systems rooted in traditions like Christian, Jewish, and Islamic thought, where scripture or revelation is taken as the source of moral law.
