St. Thomas was one of the twelve apostles and is the patron saint of architects. He was unwilling to believe the accounts of the other Apostles who had seen the risen Lord, and only believed when Jesus appeared a second time. He put his fingers through the wounds of Jesus to confirm the Resurrection. Having being convinced of the Resurrection, he made a public profession of the divinity of Jesus by saying “My Lord and My God.”
St. Thomas eventually reached India taking the Gospel there, preaching along the Malabar Coast. There is a large Christian population to this day in that region who call themselves “Christians of St. Thomas”.
Almighty and ever living God, who strengthened your apostle Thomas with sure and certain faith in your Son’s resurrection: Grant us so perfectly and without doubt to believe in Jesus Christ, our Lord and our God, that our faith may never be found wanting in your sight; through him who lives and reigns with you and the Holy Spirit, one God, now and for ever.
