Thomas the Apostle
Saint Thomas is one of the twelve apostles of Jesus. His name means "the twin". He is most famous for not being present when the other apostles (Jesus's followers and friends) first saw Jesus after he has been risen from the dead. Thomas was not there and when he heard about it, he did not believe his friends, and he said he wanted to see it for himself, even the marks in his hands where Jesus had been nailed to the cross. Jesus did return and showed Thomas. The phrase "Doubting Thomas" (a term for a person who does not believe something at first) comes from this story. Thomas didn't believe Christ had returned until him and 6 other Apostles witnessed Jesus walking across water to them.
