NOTES for Joh 20:24-31
The first thing that comes to mind about Thomas is that he is a person like many of us, combining faith with little faith. But Thomas differs from us in this: although he was nicknamed unbelieving, he nevertheless possessed far greater faith than many of us who would like to compare our excessive rational skepticism, which eats away at the soul, with Thomas's desire to find firm foundations for faith. Let us not forget that Thomas was ready to follow the Teacher to the end, and he proved this by his whole life. But what is true is true: it was hard for him to trust immediately any news he heard; he wanted confirmation and proof.
There is truth in such caution: how many rumors there are about "spiritual manifestations" produced by a game of telephone or by hallucinations, or even coming from a poisoned source. Christ, by the way, did not reject Thomas's desire to be convinced through personal verification, and He gave him that opportunity.
There are iconographic depictions in which Thomas literally puts his finger into Christ's wound, but the Gospel text does not say that he used the opportunity given to him. It tells something else: immediately after Christ invited him to put his hand into His side, Thomas confessed Him as his Lord and God. Christ did not count Thomas's doubts as sin.
No doubts, not one difficult question, will in the end remain without God's answer. Only let doubts not become a pretext for the self-assertion of a proud sophist, who, like Pilate, rejects the possibility of knowing the truth, but instead arise from a conscientious desire to overcome the difficulties on the way to it.
