Thomas is famous for having doubted the Resurrection of Jesus and for demanding physical proof of the wounds of Christ's Crucifixion. The phrase “doubting Thomas” was coined for his lack of faith. When Jesus showed him the wounds, St. Thomas became the first person to explicitly acknowledge the divinity of Jesus.
Saint Thomas the Apostle is the patron saint of architects, builders, craftsmen, geometricians, masons, surveyors, theologians, and the blind. He is also known as the patron saint of doubters.
