John 20:22-26

And when he had said this, he breathed on them, and saith unto them, Receive ye the Holy Ghost:

Whose soever sins ye remit, they are remitted unto them; and whose soever sins ye retain, they are retained.

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

The other disciples therefore said unto him, We have seen the Lord. But he said unto them, Except I shall see in his hands the print of the nails, and put my finger into the print of the nails, and thrust my hand into his side, I will not believe.

And after eight days again his disciples were within, and Thomas with them: then came Jesus, the doors being shut, and stood in the midst, and said, Peace be unto you.
