According to Holy Scripture, the holy Apostle Thomas did not believe the reports of the other disciples about the Resurrection of Jesus Christ: “Unless I see in His hands the print of the nails, and put my finger into the print of the nails, and thrust my hand into His side, I will not believe” (John 20:25).
On the eighth day after the Resurrection, the Lord appeared to the Apostle Thomas and showed him His wounds. “My Lord and my God,” the Apostle cried out (John 20:28). “Thomas, being once weaker in faith than the other apostles,” says Saint John Chrysostom, “toiled through the grace of God more bravely, more zealously and tirelessly than them all, so that he went preaching over nearly all the earth, not fearing to proclaim the Word of God to savage nations.”
Some icons depicting this event are inscribed “The Doubting Thomas.” This is incorrect. In Greek, the inscription reads, “The Touching of Thomas.” In Slavonic, it says, “The Belief of Thomas.” When Saint Thomas touched the Life-giving side of the Lord, he no longer had any doubts.
According to Church Tradition, the holy Apostle Thomas founded Christian churches in Palestine, Mesopotamia, Parthia, Ethiopia and India. Preaching the Gospel earned him a martyr’s death. For having converted the wife and son of the prefect of the Indian city of Meliapur [Melipur], the holy apostle was locked up in prison, suffered torture, and finally, pierced with five spears, he departed to the Lord. Part of the relics of the holy Apostle Thomas are in India, in Hungary and on Mt. Athos. The name of the Apostle Thomas is associated with the Arabian (or Arapet) Icon of the Mother of God (September 6).

You were a disciple of Christ, / and a member of the divine college of Apostles. / Having been weak in faith you doubted the Resurrection of Christ, / but by feeling the wounds you believed in His all-pure Passion: / pray now to Him, O all-praised Thomas, to grant us peace and great mercy.
Kontakion — Tone 4
Thomas, the faithful servant and disciple of Christ, / filled with divine grace, cried out from the depth of his love: / “You are my Lord and my God!”
