That the Bodies of the Risen shall be otherwise organised than before

THOUGH the bodies of the risen are to be of the same species with our present bodies, still they will be otherwise organised (aliam dispositionem habebunt); and chiefly in this, that all the bodies of the risen, of good men and evil men alike, will be incorruptible. For that, three reasons may be assigned. First, in respect of the end of the resurrection, which is reward or punishment for the things done in the body; and both the one and the other is to be everlasting (B. III, Chapp. LXII, CXLV).

Secondly, in respect of the formal cause of the resurrection, which is the soul. Since the recovery of the body is a provision for the perfection of the soul, it is fitting that the body be organised in such fashion as shall suit the soul (Chap. LXXIX. But the soul is incorruptible, therefore the body shall be restored to it incorruptible. A third reason may be found in the efficient cause of the resurrection. God will restore to life bodies already corrupted and fallen to decay: much more will He be able, once He has restored life to them, to ensure that life abiding in them everlastingly.

This body, now corruptible, will be rendered incorruptible in such sort that the soul shall have perfect control over it, giving it life.* Nor shall any foreign power be able to hinder this communication of life.* Risen man then shall be immortal, not by taking up another body, that shall be incorruptible, but by his present corruptible body being made incorruptible. This corruptible mast put on incorruption (1 Cor. xv, 5 3). So then that saying, Flesh and blood shall not possess the kingdom of God (1 Cor. xv, 50), means that in the risen state the corruption of flesh and blood shall be taken away, while the substance of flesh and blood remains.*
