Are the Ten Commandments a doctrinal standard?
The Ten Commandments are not a doctrinal standard. They remain holy, perfect, and the mind of God, serving as criteria for social behavior whether Christian or non-Christian, but they do not become a criteria of doctrine. They are simply the mind of God for mankind's own good.
Les explains that being under grace rather than law does not mean the Ten Commandments are cast aside as no good. They remain holy, perfect, and the mind of God. They serve as the criteria for social behavior for both Christian and non-Christian. However, they do not become a criteria of doctrine. Because they are not a religious doctrine in themselves, Les sees no issue with having them in public schools. Everything within them is for mankind's own good.
