Glenn Peoples delivers this lecture entitled: Divine Will Based Theories of Ethics. This ethical system (also known as divine command theory) ties what is morally right or wrong to the will of God, or what God commands. A very useful introduction to the topic, which also includes responses to common criticisms.
