But if Christ rose again with the same stature with which He died, it is impious to say that when the time of the resurrection of all shall come, there shall be added to His body a bigness that it had not at His own resurrection, (for He appeared to His disciples with that body in which He had been known among them,) such that He shall be equalled to the tallest among men.
If again we say that all men’s bodies, whether tall or short, shall be alike brought to the size and stature of the Lord’s body, then much will perish from many bodies, though He has declared that “not a hair shall fall.” It remains therefore that each be raised in his own stature - that stature which he had in youth, if he died in old age; if in childhood that stature to which he would have attained had he lived. For the Apostle says not, ‘To the measure of the stature,’ but, “To the measure of the full age of Christ.” [Eph 4:13] For the bodies of the dead shall rise in youth and maturity to which we know that Christ attained. [ed. note: Hence the Roman Catholics teach that “men shall rise at a perfect age, which is thirty three;” vid. Bp. Doyle’s Christian Doctrine.]
