Anti-pelagian Writings by St. Augustine
Chapter 3 [III.]--It is One Thing to Be Mortal, Another Thing to Be Subject to Death.
Nor was there any reason to fear that if he had happened to live on here longer in his natural body, he would have been oppressed with old age, and have gradually, by increasing age, arrived at death. For if God granted to the clothes and the shoes of the Israelites that |they waxed not old| during so many years, what wonder if for obedience it had been by the power of the same [God] allowed to man, that although he had a natural and mortal body, he should have in it a certain condition, in which he might grow full of years without decrepitude, and, whenever God pleased, pass from mortality to immortality without the medium of death? For even as this very flesh of ours, which we now possess, is not therefore invulnerable, because it is not necessary that it should be wounded; so also was his not therefore immortal, because there was no necessity for its dying. Such a condition, whilst still in their natural and mortal body, I suppose, was granted even to those who were translated hence without death. For Enoch and Elijah were not reduced to the decrepitude of old age by their long life. But yet I do not believe that they were then changed into that spiritual kind of body, such as is promised in the resurrection, and which the Lord was the first to receive; only they probably do not need those aliments, which by their use minister refreshment to the body; but ever since their translation they so live, as to enjoy such a sufficiency as was provided during the forty days in which Elijah lived on the cruse of water and the cake, without substantial food; or else, if there be any need of such sustenance, they are, it may be, sustained in Paradise in some such way as Adam was, before he brought on himself expulsion therefrom by sinning. And he, as I suppose, was supplied with sustenance against decay from the fruit of the various trees, and from the tree of life with security against old age.
