Part 158 Someone asked, “I have heard the Decalogue is a perfect moral code. Is that true?” The Decalogue is the Ten Commandments. The Decalogue is as perfect as any law from God would be (John 1:1). However, if one were implying that no other commandments were needed for obedience, then the answer is no! Absolutely not (Deut. 4:2)! The Ten Commandments were only a part of the Law of Moses.
