Anti-pelagian Writings by St. Augustine
Chapter 68 [XXXVII.]--If Adam Was Not Created of Such a Character as that in Which We are Born, How is It that Christ, Although Free from Sin, Was Born an Infant and in Weakness?
Some one will ask, If this nature is not pure, but corrupt from its origin, since Adam was not created thus, how is it that Christ, who is far more excellent, and was certainly born without any sin of a virgin, nevertheless appeared in this weakness, and came into the world in infancy? To this question our answer is as follows: Adam was not created in such a state, because, as no sin from a parent preceded him, he was not created in sinful flesh. We, however, are in such a condition, because by reason of his preceding sin we are born in sinful flesh. While Christ was born in such a state, because, in order that He might for sin condemn sin, He assumed the likeness of sinful flesh. The question which we are now discussing is not about Adam in respect of the size of his body, why he was not made an infant but in the perfect greatness of his members. It may indeed be said that the beasts were thus created likewise, -- nor was it owing to their sin that their young were born small. Why all this came to pass we are not now asking. But the question before us has regard to the vigor of man's mind and his use of reason, by virtue of which Adam was capable of instruction, and could apprehend God's precept and the law of His commandment, and could easily keep it if he would; whereas man is now born in such a state as to be utterly incapable of doing so, owing to his dreadful ignorance and weakness, not indeed of body, but of mind, -- although we must all admit that in every infant there exists a rational soul of the self-same substance (and no other) as that which belonged to the first man. Still this great infirmity of the flesh, clearly, in my opinion, points to a something, whatever it may be, that is penal. It raises the doubt whether, if the first human beings had not sinned, they would have had children who could use neither tongue, nor hands, nor feet. That they should be born children was perhaps necessary, on account of the limited capacity of the womb. But, at the same time, it does not follow, because a rib is a small part of a man's body, that God made an infant wife for the man, and then built her up into a woman. In like manner, God's almighty power was competent to make her children also, as soon as born, grown up at once.
