Thomas Aquinas

“ The strength of the species is said to be more perfect in a child than in a young man, as regards the ability to transform nourishment in a certain way, even as it is more perfect in the seed than in the mature man. In youth, however, it is more perfect as regards the term of completion. Wherefore that which belonged principally to the truth of human nature will be brought to that perfection which it has in the age of youth, and not to that perfection which it has in the age of a child, wherein the humors have not yet reached their ultimate disposition. ”

“ I answer that, The resurrection will not be necessary to man on account of his primary perfection, which consists in the integrity of those things that belong to his nature, since man can attain to this in his present state of life by the action of natural causes; but the necessity of the resurrection regards the attainment of his ultimate perfection, which consists in his reaching his ultimate end. ”

“ It would seem that all will not rise again of the same, namely the youthful age. Because God will take nothing pertaining to man's perfection from those who rise again, especially from the blessed. Now age pertains to the perfection of man, since old age is the age that demands reverence. Therefore the old will not rise again of a youthful age. ”

“ Consequently those natural operations which are directed to cause or preserve the primary perfection of human nature will not be in the resurrection: such are the actions of the animal life in man, the action of the elements on one another, and the movement of the heavens; wherefore all these will cease at the resurrection. And since to eat, drink, sleep, beget, pertain to the animal life, being directed to the primary perfection of nature, it follows that they will not be in the resurrection. ”

“ Further, generation is directed to supply the defect resulting from death, and to the multiplication of the human race: and eating is directed to make up for waste, and to increase quantity. But in the state of the resurrection the human race will already have the number of individuals preordained by God, since generation will continue up to that point. In like manner each man will rise again in due quantity; neither will death be any more, nor any waste affect the parts of man. ”

“ Therefore since all men have the same specific form, there should be the same measure of quantity in respect of matter in all, unless an error should occur. But the error of nature will be set right at the resurrection. ”

“ As the Philosopher says (Ethic. vii, 12, x, 5) , the pleasures of the body are medicinal, because they are applied to man for the removal of weariness; or again, they are unhealthy, in so far as man indulges in those pleasures inordinately, as though they were real pleasures: just as a man whose taste is vitiated delights in things which are not delightful to the healthy. Consequently it does not follow that such pleasures as these belong to the perfection of beatitude, as the Jews and Turks maintain, and certain heretics known as the Chiliasts asserted ”

“ Therefore all will not rise again of the same quantity, but each one will rise again of that quantity which would have been his at the end of his growth if nature had not erred or failed: and the Divine power will subtract or supply what was excessive or lacking in man. ”

“ When Christ partook of that meal, His eating was an act, not of necessity as though human nature needed food after the resurrection, but of power, so as to prove that He had resumed the true human nature which He had in that state wherein He ate and drank with His disciples. There will be no need of such proof at the general resurrection, since it will be evident to all. ”

“ Art. 4 - Whether all will rise again to animal life so as to exercise the functions of nutrition and generation? Objection 1: It would seem that they will rise again to the animal life, or in other words that they will make use of the acts of the nutritive and generative powers. ”
