"Now Thomas, one of the twelve, called the Twin, was not with them when Jesus came. So the other disciples told him, “We have seen the Lord.” But he said to them, “Unless I see in his hands the mark of the nails, and place my finger into the mark of the nails, and place my hand into his side, I will never believe.” (John 20:24-25)
We see what a poor thing the human heart is when it begins to grow faint, that we cannot strengthen and comfort it again. Both the other disciples and Thomas did not only hear during the time they were with the Lord that he taught the people with great authority, and later also saw how he confirmed his doctrine by the great miracles performed on the blind, the lame, the lepers, the dumb etc., whom he cured; but also that he raised three persons from the dead. And, as it appears, St. Thomas was the most fearless and courageous of all the disciples, in that he said when Christ wished to go again into Judea to Lazarus who was dead: “Let us also go, that we may die with him,” (John 11:16.) Such fine characters were the disciples of Christ and especially St. Thomas, yet he could not believe that the Lord himself arose from the dead and was alive.
Moreover, we see in the apostles that we are truly nothing when Christ withdraws his hand and we are left to ourselves. The women, Mary Magdalene, and the others, announced it, and now the disciples themselves proclaim that they had seen the risen Lord. Yet St. Thomas is stubborn and will not believe it and he will not be satisfied even if he see him, unless it be that he sees the print of the nails in his hands and puts his fingers into the print of the nails and his hand into his side.
Thomas is an illustration of the power of Christ’s resurrection. We hear how firm and even stiff-necked he was in unbelief, that although the other disciples unitedly testified that they had seen the risen Lord, yet he simply will not believe it. He appears to have been a fine and brave character who had thoroughly concluded that he would not so soon believe the others. For he had seen that the Lord only three days before was put to death on the cross and the nails driven through his hands and feet and the spear pierced his side. This picture was so indelibly and deeply impressed upon him that he simply could not in the least believe what the others told him, that Christ was risen. He thus utters a hyperbole, an exaggerated statement, that he will not believe his eyes alone, but will feel and grope about Christ’s body with his hands. As if he would say: No one shall persuade me to believe, but I will stand so firmly upon no, that I will not believe even if I see him, as you say you saw him. But should I believe it, then he must come so near to me, that, if it were possible, I may touch his soul and put my hands into his eyes.
That is to be steeped very firmly and deeply in unbelief. And it is wonderful what he means by it that he at once proposes a thing absurd, to put his hand and finger into the openings of his wounds. For he had always been so smart as to think: Since Christ was again alive, had conquered death and was rid of all the bruises from the scourging and the crown of thorns, he would surely have healed and removed also the five wounds.
Now, this has happened for our example and consolation, that the great apostle also had to fail and stumble, in which we see how Christ shows and conducts himself toward his weak disciples, that he can tolerate also such who are still as hard and stubborn as St. Thomas is here, and that he will not on that account condemn and disown them and by this he teaches us that we should become neither offended nor despondent because of that; but in harmony with this his example gently go on with them, serve their weakness, with our strength until they become established and grow strong.
