Thomas the Apostle

Thomas the Apostle — called "Didymus" (the Twin) — is known above all for his initial refusal to believe in the Resurrection without physical proof, and for his subsequent confession of faith when the risen Christ appeared to him: "My Lord and my God!" — the most explicit affirmation of Christ's divinity in the four Gospels (John 20:24–28; CCC 644).

Thomas in the Gospels

Thomas appears three times in John's Gospel. Before the raising of Lazarus, he courageously declared: "Let us also go, that we may die with him" (John 11:16). At the Last Supper, his honest question — "Lord, we don't know where you are going, so how can we know the way?" — prompted Jesus's famous response: "I am the way, the truth, and the life" (John 14:5–6; CCC 2466).

Doubting Thomas

After the Resurrection, when the other Apostles told Thomas they had seen the Lord, Thomas refused to believe without physical evidence: "Unless I see the nail marks in his hands and put my finger where the nails were, and put my hand into his side, I will not believe" (John 20:25). Eight days later, Jesus appeared again and invited Thomas to touch his wounds. Thomas's response — "My Lord and my God!" — is the climax of John's Gospel and a direct affirmation of Jesus's divinity (CCC 644).

Thomas's Mission

Tradition holds that Thomas carried the Gospel to the Indian subcontinent — the "Thomas Christians" of Kerala trace their community to his apostolate. He was martyred in India around 72 AD. His feast day is July 3.

Frequently Asked Questions

Is doubt sinful? Thomas's doubt was not a sin of unbelief but an honest expression of the limits of his faith. Jesus did not rebuke him — he met him where he was and gave him what he needed. The Catechism teaches that involuntary doubt is not sinful; what matters is the honest seeking of truth (CCC 2088).
