58 But, further, no one who is endued with reason can impute to God a soul; though it is written in many places that the soul of God hates sabbaths and new moons: and also that it delights in certain things. But this is merely a conventional expression to be understood in the same way as when God is spoken of as possessing body, with hands, and eyes, and fingers, and arms, and heart. As the Lord said, A Spirit has not flesh and bones: He then Who is, and changes not, cannot have the limbs and parts of a tangible body. He is a simple and blessed nature, a single, complete, all-embracing Whole. God is therefore not quickened into life, like bodies, by the action of an indwelling soul, but is Himself His own life.
