Chapter 2 — Anathemas VIII–XIV
Section 8. VIII. If anyone uses the expression 'of two natures' confessing that a union was made of the Godhead and of the humanity, or the expression 'the one nature made flesh of God the Word,' and shall not so understand those expressions as the holy Fathers have taught, to wit: that from the divine and human natures a union was made according to subsistence, and that one Christ was formed; but from these expressions shall try to introduce one nature or substance of the Godhead and manhood of Christ: let him be anathema. For in teaching that the only-begotten Word was united according to subsistence we do not mean to say that there was made a mutual confusion of natures, but rather each of the two remained what it was, and we understand that the Word was united to the flesh.
