John 20:20-23

And when he had said this, he showed unto them his hands and his side. The disciples therefore were glad, when they saw the Lord. Jesus therefore said to them again, Peace be unto you: as the 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 Spirit: whose soever sins ye forgive, they are forgiven unto them; whose soever sins ye retain, they are retained.
