A friend of mine recently asked a great question: Why does Jesus still have the wounds from the cross? He has his perfected body, why keep the wounds? Will martyrs keep their wounds they received in Christ’s name upon the resurrection of the dead and the final glorification?
Saint Thomas Aquinas answered this question in Summa theologiae IIIa q. 54, a. 4: “Whether Christ’s body ought to have risen with its scars?” He gives five reasons for why Christ rose with the scars of His passion:
I answer that, It was fitting for Christ’s soul at His Resurrection to resume the body with its scars. In the first place, for Christ’s own glory. For Bede says on Luke 24:40 that He kept His scars not from inability to heal them, “but to wear them as an everlasting trophy of His victory.”Hence Augustine says (De Civ. Dei xxii): “Perhaps in that kingdom we shall see on the bodies of the Martyrs the traces of the wounds which they bore for Christ’s name: because it will not be a deformity, but a dignity in them; and a certain kind of beauty will shine in them, in the body, though not of the body.”
Secondly, to confirm the hearts of the disciples as to “the faith in His Resurrection” (Bede, on Luke 24:40).
Thirdly, “that when He pleads for us with the Father, He may always show the manner of death He endured for us” (Bede, on Luke 24:40).
Fourthly, “that He may convince those redeemed in His blood, how mercifully they have been helped, as He exposes before them the traces of the same death” (Bede, on Luke 24:40).
Lastly, “that in the Judgment-day He may upbraid them with their just condemnation” (Bede, on Luke 24:40). Hence, as Augustine says (De Symb. ii): “Christ knew why He kept the scars in His body. For, as He showed them to Thomas who would not believe except he handled and saw them, so will He show His wounds to His enemies, so that He who is the Truth may convict them, saying: ‘Behold the man whom you crucified; see the wounds you inflicted; recognize the side you pierced, since it was opened by you and for you, yet you would not enter.'”
