Since man is composed of body and soul, he is moved by two laws, that of the flesh and that of the Spirit (Romans 7:23). The law of the flesh operates by virtue of the senses; the law of the Spirit operates by virtue of the intellect. The first law, operating by virtue of the senses, automatically binds one closely to matter; the second law, operating by virtue of the intellect, brings about direct union with God.
