St Thomas the Apostle - Neston Church, Wirral
Thomas the Apostle, also called Doubting Thomas or Didymus (meaning "Twin") was one of the Twelve Apostles of Jesus. He is best known for disbelieving Jesus' resurrection when first told of it, then proclaiming "My Lord and my God" on seeing Jesus in John 20:28. He was perhaps the only Apostle who went outside the Roman Empire to preach the Gospel. He is also believed to have crossed the largest area, which includes the Persian Empire and India.
When the feast of Saint Thomas was inserted in the Roman calendar in the ninth century, it was assigned to 21 December, although the Martyrology of St Jerome had a mention of the Apostle on 3 July, the date to which the Roman celebration was transferred in 1969, so that it would no longer interfere with the major ferial days of Advent.
