One of the Twelve, called Didymus (‘the twin’, John 11: 16). He is named in the lists of apostles (e.g. Luke 6: 15) but only becomes important in the gospel of John. He has earned the title ‘doubting Thomas’ because in John's narrative he declined to believe in the resurrection of Jesus until he was given tangible evidence (John 20: 24–9). When Jesus made himself known, Thomas exclaimed, ‘My Lord and my God’ (20: 28). Such an address to Jesus shows that by the time John was written, the rigid monotheism of Judaism was beginning to have to take on board the Christian veneration of Jesus. It implies a belief that Jesus is exalted to the throne of God and seems to echo John 10: 30 (‘I and the Father are one’).
