Aquinas Thought of Everything
Below is a quote from Summa Contra Gentiles. I've been familar with the notion that St. Thomas said we'd all be 33 in Heaven regardless of when we died (before or after that age), but no one every seemed to know where he'd said it. Well here it is, along with an interesting discussion on the other qualities of the glorified body:
From Jacques Maritain Center: GC 4.88:
"STILL we must not suppose, what some have thought, that female sex has no place in the bodies of the risen Saints. For since resurrection means the reparation of the defects of nature, nothing of what makes for the perfection of nature will be withdrawn from the bodies of the risen. Now among other organs that belong to the integrity of the human body are those which minister to generation as well in male as in female. These organs therefore will rise again in both. Nor is this conclusion impaired by the fact that there will be no longer any use of these organs (Chap. LXXXIII). If that were any ground for their absence from the risen body, all the organs bearing on digestion and nutrition should be absent, for there will not be any use for them either: thus great part of the organs proper to man would be wanting in the risen body. We conclude that all such organs will be there, even organs of which the function has ceased: these will not be there without a purpose, since they will serve to make up the restored integrity of the natural body.*
Neither is the weakness of the female sex inconsistent with the perfection of the resurrection. Such weakness is no departure from nature, but is intended by nature.* This natural differentiation will argue the thoroughgoing perfection of nature, and commend the divine wisdom that arranges creation in diversity of ranks and orders. Nor is there anything to the contrary in the expression of the Apostle: Till we all meet and attain to the unity of faith and recognition of the Son of God, even to a perfect man, to the measure of the full stature of Christ (Eph. iv, 13). This does not mean that in that meeting in which the risen shall go forth to meet Christ in the air* every one shall be of the male sex, but it indicates the perfection and strength of the Church, for the whole Church shalt be like a perfect, full-grown man, going out to meet Christ.*
Again, all must rise at the age of Christ,* which is the age of perfect manhood, for the sake of the perfection of nature, which is at its best in this age above others.
