St. Thomas is best known for his role in verifying the Resurrection of his Master. Thomas' unwillingness to believe that the other Apostles had seen their risen Lord on the first Easter Sunday merited for him the title of "doubting Thomas." Eight days later, on Christ's second apparition, Thomas was gently rebuked for his skepticism and furnished with the evidence he had demanded - seeing in Christ's hands the point of the nails and putting his fingers in the place of the nails and his hand into His side. At this, St. Thomas became convinced of the truth of the Resurrection and exclaimed: "My Lord and My God," thus making a public Profession of Faith in the Divinity of Jesus.St. Thomas is also mentioned as being present at another Resurrection appearance of Jesus - at Lake Tiberias when a miraculous catch of fish occurred. This is all that we know about St. Thomas from the New Testament.
Tradition says that at the dispersal of the Apostles after Pentecost this saint was sent to evangelize the Parthians, Medes, and Persians; he ultimately reached
India, carrying the Faith to the Malabar coast, which still boasts a large native population calling themselves "Christians of St. Thomas." He capped his life by shedding his blood for his Master, speared to death at a place called Calamine. His feast day is July 3rd and he is the patron of architects.
