Gregory the Great
Catena Aurea · Johannesevangelium 20
Then the same day at evening, being the first day of the week, when the doors were shut where the disciples were assembled for fear of the Jews, came Jesus and stood in the midst, and saith unto them, Peace be unto you. And when he had so said, he shewed unto them his hands and his side. Then were the disciples glad, when they saw the Lord. Then said Jesus to them again, Peace be unto you: as my Father hath sent me, even so send I you. 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.
(Hom. xxvi.) We must understand that those who first received the Holy Ghost, for innocence of life in themselves, and preaching to a few others, received it openly after the resurrection, that they might profit not a few only, but many. The disciples who were called to such works of humility, to what a height of glory are they led! Lo, not only have they salvation for themselves, but are admitted1 to the powers of the supreme Judgment-seat; so that, in the place of God, they retain some men’s sins, and remit others. Their place in the Church, the Bishops now hold; who receive the authority to bind, when they are admitted to the rank of government. Great the honour, but heavy the burden of the place. It is ill if one who knows not how to govern his own life, shall be judge of another’s.
