6. But we have always maintained the birth
existing out of time: we have taught that God the Son is God of
the same nature with God the Father, not co-equal with the Unbegotten,
for He was not Himself Unbegotten, but, as the Only-begotten, not
unequal because begotten; that the Two are One, not by the giving of a
double name to one Person, but by a true begetting and being begotten;
that neither are there two Gods, different in kind, in our faith, nor
is God solitary because He is one, in the sense in which we confess the
mystery of the Only-begotten God: but that the Son is both
indicated in the name of, and exists in, the Father, Whose name and
Whose nature are in Him, while the Father by His name implies, and
abides in, the Son, since a son cannot be spoken of, or exist, except
as born of a father. Further, we say that He is the living copy
of the living nature, the impression of the divine seal upon the divine
nature, so undistinguished from God in power and kind, that neither His
works nor His words nor His form are other than the
Father’s: but that, since the image by nature possesses the
nature of its author, the Author also has worked and spoken and
appeared through His natural image.
