THE CHRIST-GOD
WE ought to have faith in God the Saviour, Jesus Christ, because that is faith in the visible God in Whom is the Invisible; and faith in the visible God, Who is at once Man and God, enters into man. For while faith is spiritual in essence it is natural in form, for everything spiritual, in order to be anything with a man, is received by him in what is natural.
—True Christian Religion, n. 339
Man's conjunction with the Lord is not with His supreme Divine Being itself, but with His Divine Humanity, and by this with the supreme Divine Being; for man can have no idea whatever of the supreme Divine Being of the Lord, utterly transcending his thought as it does; but of His Divine Human Being he can have an idea. Hence the Gospel according to John says that no one has at any time seen God except the only-begotten Son, and that there is no approach to the Father save by Him. For the same reason He is called a Mediator.
