Thomas, one of the twelve, called Twin, was not with them when Jesus came. 

The other disciples said to him: ‘We have seen the Lord.’ But he said to them: ‘Unless I see, in his hands, the place of the nails, and put my finger into the place of the nails and put my hand into his side I will not believe it. ‘

And after eight days his disciples were again inside and Thomas with them. Jesus came, even though the doors were locked and he stood among them and said: ‘ Peace be on  you all.’ 

Then he said to Thomas: ‘Reach out your finger here, and see my hands, and reach out your hands and put it into my side and do not be an unbeliever but a believer.  

Thomas replied: ‘My Lord, and my God. ‘

Jesus said to him: ‘You have believed because you have seen me. Blessed are those who have not seen and have believed.’

Be thou a bright flame before me,
Be thou a guiding star above me
Be thou a smooth path below me
Be thou a kindly shepherd behind me
Today – tonight -forever
Amen.

St Columba
