"TWO NATURES IN CHRIST. We therefore acknowledge two natures or substances, the divine and the human, in one and the same Jesus Christ our Lord (Heb., ch. 2). And we say that these are bound and united with one another in such a way that they are not absorbed, or confused, or mixed, but are united or joined together in one person the properties of the natures being unimpaired and permanent.
NOT TWO BUT ONE CHRIST. Thus we worship not two but one Christ the Lord. We repeat: one true God and man. With respect to his divine nature he is consubstantial with the Father, and with respect to the human nature he is consubstantial with us men, and like us in all things, sin excepted (Hebrews 4:15)."
