Christ is not the self, but that which remains when there is no self. He is the form (the vessel) that is identical with the substance, and he is not multiple forms, but one eternal form. Christ is the act, the manifestation and extension of God that is not separate from God. We cannot comprehend "that" which acts or "that" which smiles, but we all know the act - the smile that is Christ himself. Thus Christ turns out to be all that is knowable about God, because without his acts, God could not be known. Act itself is God's revelation and this revelation is not separate from God but is God himself. This I believe is what Christ would have us see; this is his completed message to man. But who can understand it?
