The divine command theory holds that morality finds its origin in God or that God is somehow closely connected to morality. Many people across the world hold a related, though different belief that Religious belief is required for proper moral behavior. In this paper, I look at a number of evolutionary and cognitive explanations (supernatural punishment theory, big gods theory, moral dyad, and costly signaling) that purport to explain why people hold beliefs concerning a close connection between God and morality. I assess whether any of these theories provide a reason for epistemic concern.
