Final answer:
Divine Command Theory is stated to be false because it holds that morality is based on any and all commands of God, not just the Ten Commandments, and is not used as a moral basis by major organized religions.
Step-by-step explanation:
The statement that Divine Command Theory claims that the 10 Commandments are the source of morality is false. Divine Command Theory posits that what is morally good is whatever God commands, which is not restricted to any scripture or set of rules like the Ten Commandments. According to this theory, God could issue new commands, even if they change or contradict previous ones. This theory is distinct from other ethical frameworks and is not the basis for the morality of major organized religions, which have tended to reject it in favor of concepts like Natural Law Theory.
