Tertullian

“ Now, of these two names Jesus Christ, the former is the proper one, which was given to Him by the angel; and the latter is only an adjunct, predicable of Him from His anointing,—thus suggesting the proviso that Christ must be the Son, not the Father. How blind, to be sure, is the man who fails to perceive that by the name of Christ some other God is implied, if he ascribes to the Father this name of Christ! ”

“ You possess indeed all his writings, which testify plainly to the same effect, and set forth Two—God the Father, and our Lord Jesus Christ, the Son of the Father. (They also testify) that Jesus is Himself the Christ, and under one or the other designation the Son of God. For precisely by the same right as both names belong to the same Person, even the Son of God, does either name alone without the other belong to the same Person. Consequently, whether it be the name Jesus which occurs alone, Christ is also understood, because Jesus is the Anointed One ”

“ He of course shows plainly enough that there is above Himself another Father and another God. If, again, the Father is Christ, He must be some other Being who “strengtheneth the thunder, and createth the wind, and declareth unto men His Christ.” ”
