“And in Him is no darkness at all,”—that is, no passion, no keeping up of evil respecting any one, [He] destroys no one, but gives salvation to all. Light moreover signifies, either the precepts of the Law, or faith, or doctrine. Darkness is the opposite of these things. Not as if there were another way; since there is only one way according to the divine precepts. For the work of God is unity. Duality and all else that exists, except unity, arises from perversity of life.
