Well, inasmuch as the Word was from the first, He was and is the divine source of all things; but inasmuch as He has now assumed the name Christ, consecrated of old, and worthy of power, he has been called by me the New Song. This Word, then, the Christ, the cause of both our being at first (for He was in God) and of our well-being, this very Word has now appeared as man, He alone being both, both God and man—the Author of all blessings to us; by whom we, being taught to live well, are sent on our way to life eternal.
Clement of Alexandria
Exhortation to the Heathen
Chapter I
