The Christian understanding of the Trinity is unique among all religious faiths. Because God Himself is Triune. He Himself is the model for mon in society.

It tollows from the Creator-creature distinction that God does not depend on man.
Scripture is needed to understand creation properly.
Only God knows all fully and perfectly while man, the creature. Man also depends upon God for absolute. reliable morality. Without God man's morality con only be relative and unreliable. As the great tussian writer Dostoevsky said. Nazi holocaust or the Communist Gulog justify themselves by their power and the absence of any absolute standard of right and wrong.
