25. The essential likeness conformed to the
Father’s essence in kind is also taught to be identical in
time: lest He who is the image of God, who is the Word, who is
God with God in the beginning, who is like the Father, by the insertion
of times between Himself and the Father should not have in Himself in
perfection that which is both image, and Word, and God. For if He
be proclaimed to be younger in time, He has lost the truth of the image
and likeness: for that is no longer likeness which is found to be
dissimilar in time. For that very fact that God is Father
prevents there being any time in which He was not Father:
consequently there can be no time in the Son’s existence in which
He was not Son. Wherefore we must neither call the Father older
than the Son nor the Son younger than the Father: for the true
meaning of neither name can exist without the other.
