What Makes Something Morally Good or Bad? Natural Law vs. Divine Command Theory (Part 3)

The two predominant positions within Christianity that answer the question of “Where does objective morality come from?” are known as Natural Law Theory and Divine Command Theory. Both theories have strengths and weaknesses, which leads to robust debate between proponents of each. Natural Law Theory says that both human moral values (i.e., what things are good and bad) and moral obligations (i.e., what things are right and wrong to do) come from facts about what causes human beings to flourish. In Natural Law Theory, God created the world, including human beings, and thus something is good or right when it causes human beings to flourish. On the other hand, Divine Command Theory says that our moral obligations come from God’s commands. Right and wrong are determined by what God commands us to do, and God commands us according to what is good. In this lecture, Adam explores each of these theories and discusses objections against each offered by proponents of the other.
