Tertullian

“ Himself, and took upon Him the form of a servant,” not the reality, “and was made in the likeness of man,” not a man, “and was found in fashion as a man,” [9] not in his substance, that is to say, his flesh; just as if to a substance there did not accrue both form and likeness and fashion. It is well for us that in another passage (the apostle) calls Christ “the image of the invisible God.” ”

“ For what is found, manifestly possesses existence. Therefore, as He was found to be God by His mighty power, so was He found to be man by reason of His flesh, because the apostle could not have pronounced Him to have “become obedient unto death,” [13] if He had not been constituted of a mortal substance. ”

“ But since he is truly God, as the Son of the Father, in His fashion and image, He has been already by the force of this conclusion determined to be truly man, as the Son of man, “found in the fashion” and image “of a man.” ”
