1. ALL RELIGION IS OF THE LIFE, AND THE LIFE OF RELIGION IS TO DO THAT WHICH IS GOOD. Every man who has religion knows and acknowledges that he who leads a good life is saved, and that he who leads an evil life is damned; for he knows and acknowledges that the man who lives aright thinks aright, not only about God but also about his neighbor; but not so the man whose life is evil. The life of man is his love, and that which he loves he not only likes to be doing, but also likes to be thinking. The reason therefore why we say that the life is to do that which is good is that doing what is good acts as a one with thinking what is good, for if in a man these two things do not act as a one, they are not of his life. The demonstration of these matters shall now follow.
