Saint Thomas is invoked as patron of construction workers. Saint Thomas, called Didymus (the Twin) in the Gospel of John (John 11:16, 20:24, 21:2), was one of the Twelve Apostles. The Synoptic Gospels list him among the Twelve (Matthew 10:3, Mark 3:18, Luke 6:15) but record nothing distinctive of him.
