The following is an excerpt from “On the Incarnation” by St. Athanasius the Great
So then, men having thus become brutalized, and demoniacal deceit thus clouding every place, and hiding the knowledge of the true God, what was God to do? To keep still silence at so great a thing, and suffer men to be led astray by demons and not to know God?
And what was the use of man having been originally made in God’s image? For it had been better for him to have been made simply like a brute animal, than, once made rational, for him to live the life of the brutes. Or where was any necessity at all for his receiving the idea of God to begin with? For if he be not fit to receive it even now, it were better it had not been given him at first.
Or what profit to God Who has made them, or what glory to Him could it be, if men, made by Him, do not worship Him, but think that others are their makers? For God thus proves to have made these for others instead of for Himself. Once again, a merely human king does not let the lands he has colonized pass to others to serve them, nor go over to other men; but he warns them by letters, and often sends to them by friends, or, if need be, he comes in person, to put them to rebuke in the last resort by his presence, only that they may not serve others and his own work be spent for naught. Shall not God much more spare His own creatures, that they be not led astray from Him and serve things of nought? Especially since such going astray proves the cause of their ruin and undoing, and since it was unfitting that they should perish which had once been partakers of God’s image.
What then was God to do? Or what was to be done save the renewing of that which was in God’s image, so that by it men might once more be able to know Him? But how could this have come to pass save by the presence of the very Image of God, our Lord Jesus Christ? For by men’s means it was impossible, since they are but made after an image; nor by angels either, for not even they are (God’s) images. Whence the Word of God came in His own person, that, as He was the Image of the Father, He might be able to create afresh the man after the image.
But, again, it could not else have taken place had not death and corruption been done away. Whence He took, in natural fitness, a mortal body, that while death might in it be once for all done away, men made after His Image might once more be renewed. None other then was sufficient for this need, save the Image of the Father.
