I answer that, As stated above (A. 2), Christ's body in the Resurrection was "of the same nature, but differed in glory." Accordingly, whatever goes with the nature of a human body, was entirely in the body of Christ when He rose again. Now it is clear that flesh, bones, blood, and other such things, are of the very nature of the human body. Consequently, all these things were in Christ's body when He rose again; and this also integrally, without any diminution; otherwise it would not have been a complete resurrection, if whatever was lost by death had not been restored. Hence our Lord assured His faithful ones by saying (Matt. 10:30): "The very hairs of your head are all numbered": and (Luke 21:18): "A hair of your head shall not perish."
But to say that Christ's body had neither flesh, nor bones, nor the other natural parts of a human body, belongs to the error of Eutyches, Bishop of Constantinople, who maintained that "our body in that glory of the resurrection will be impalpable, and more subtle than wind and air: and that our Lord, after the hearts of the disciples who handled Him were confirmed, brought back to subtlety whatever could be handled in Him" [*St. Gregory, Moral. in Job 14:56]. Now Gregory condemns this in the same book, because Christ's body was not changed after the Resurrection, according to Rom. 6:9: "Christ rising from the dead, dieth now no more." Accordingly, the very man who had said these things, himself retracted them at his death. For, if it be unbecoming for Christ to take a body of another nature in His conception, a heavenly one for instance, as Valentine asserted, it is much more unbecoming for Him at His Resurrection to resume a body of another nature, because in His Resurrection He resumed unto an everlasting life, the body which in His conception He had assumed to a mortal life.
Reply Obj. 1: Flesh and blood are not to be taken there for the nature of flesh and blood, but, either for the guilt of flesh and blood, as Gregory says [*St. Gregory, Moral. in Job 14:56], or else for the corruption of flesh and blood: because, as Augustine says (Ad Consent., De Resur. Carn.), "there will be neither corruption there, nor mortality of flesh and blood." Therefore flesh according to its substance possesses the kingdom of God, according to Luke 24:39: "A spirit hath not flesh and bones, as you see Me to have." But flesh, if understood as to its corruption, will not possess it; hence it is straightway added in the words of the Apostle: "Neither shall corruption possess incorruption."
Reply Obj. 2: As Augustine says in the same book: "Perchance by reason of the blood some keener critic will press us and say; If the blood was" in the body of Christ when He rose, "why not the rheum?" that is, the phlegm; "why not also the yellow gall?" that is, the gall proper; "and why not the black gall?" that is, the bile, "with which four humors the body is tempered, as medical science bears witness. But whatever anyone may add, let him take heed not to add corruption, lest he corrupt the health and purity of his own faith; because Divine power is equal to taking away such qualities as it wills from the visible and tractable body, while allowing others to remain, so that there be no defilement," i.e. of corruption, "though the features be there; motion without weariness, the power to eat, without need of food."
Reply Obj. 3: All the blood which flowed from Christ's body, belonging as it does to the integrity of human nature, rose again with His body: and the same reason holds good for all the particles which belong to the truth and integrity of human nature. But the blood preserved as relics in some churches did not flow from Christ's side, but is said to have flowed from some maltreated image of Christ. _______________________
FOURTH ARTICLE [III, Q. 54, Art. 4]
Whether Christ's Body Ought to Have Risen with Its Scars?
Objection 1: It would seem that Christ's body ought not to have risen with its scars. For it is written (1 Cor. 15:52): "The dead shall rise incorrupt." But scars and wounds imply corruption and defect. Therefore it was not fitting for Christ, the author of the resurrection, to rise again with scars.
Obj. 2: Further, Christ's body rose entire, as stated above (A. 3). But open scars are opposed to bodily integrity, since they interfere with the continuity of the tissue. It does not therefore seem fitting for the open wounds to remain in Christ's body; although the traces of the wounds might remain, which would satisfy the beholder; thus it was that Thomas believed, to whom it was said: "Because thou hast seen Me, Thomas, thou hast believed" (John 20:29).
Obj. 3: Further, Damascene says (De Fide Orth. iv) that "some things are truly said of Christ after the Resurrection, which He did not have from nature but from special dispensation, such as the scars, in order to make it sure that it was the body which had suffered that rose again." Now when the cause ceases, the effect ceases. Therefore it seems that when the disciples were assured of the Resurrection, He bore the scars no longer. But it ill became the unchangeableness of His glory that He should assume anything which was not to remain in Him for ever. Consequently, it seems that He ought not at His Resurrection to have resumed a body with scars.
