Today is the Feast of St. Thomas, Apostle. The Gospel reading at Mass comes from John 20. Thomas, one of the Twelve, was not with them when Jesus came. The other disciples told him that they had seen the Lord, but Thomas said, "Unless I see the mark of the nails in his hands and put my finger into the nailmarks and put my hand into his side, I will not believe." A week later Thomas was with the disciples and Jesus came, although the doors were locked, and said, "Peace be with you." Then he said to Thomas, "Put your finger here and see my hands, and bring your hand and put it into my side, and do not be unbelieving, but believe." Thomas answered, "My Lord and my God!" Jesus said to him, "Have you come to believe because you have seen me? Blessed are those who have not seen and have believed."
Many of us today are very much like Thomas ~ we would not believe unless we see hard evidence. John simply recorded what he had witnessed ~ Thomas' about-face should turn us into believers too. Jesus last saying above, Blesses are those who have not seen and have believed, should further encourage us to believe that Jesus is our Lord and our God.
