32. It was indeed indispensable that He who is by nature the Creator of the being of all things should Himself, through grace, accomplish their deification, and in this way reveal Himself to be not only the author of being but also the giver of eternal well-being. Every creature is totally ignorant both of its own essential being and of that of every other created thing; in consequence no created thing has by nature foreknowledge of anything that will come into existence. Only God has such foreknowledge, and He transcends created things. For He knows what He is in His essence and He knows of the existence of everything made by Him before it comes into being; and it is His purpose to endow created things through grace with a knowledge both of their own essential being and of that of other things; for He will reveal to them the inner principles of their creation, pre-existent in a unified manner within Himself.
We don’t know God. We don’t truly know each other. And often, we do not even know ourselves. We can’t follow Polonius’ maxim, “To thine own self be true,” because we do not know our deepest self or how to be true to it. Before we can be deified, before we can be one with God, we have to be healed. We no longer know what it means to be a human being and we cannot know ourselves or be one with others until we have our true humanity restored. Jesus, in part, became man to restore to us our humanity. That’s one of the reasons it’s so important that Jesus was fully human in every way except sin. He became the faithful man we could not be.
