Caput V: Et in unum Dominum.

Caput IX: Deum de Deo, lumen de lumine, Deum verum de Deo vero.
Caput X: Genitum, non factum.
Caput XI: Consubstantialem Patri.
Consubstantial with the Father.
Note that in natural things "consubstantial" is said of that which is of conforming nature with another, so that "consubstantial" would denote not unity but union. The theologian, however, who begs terms from the natural philosopher, uses "consubstantial" in place of "of one substance." Nevertheless the Son is said to be consubstantial with the Father, so that it does not connote a union of nature but a unity.
[And born of the Father] — this is said only against the heresy of Nestorius and Arius.
