Jesus said to them again, Peace be with you. As the Father has sent me, even so I send you. And when he had said this, he breathed on them, and said to them, Receive the Holy Spirit. If you forgive the sins of any, they are forgiven; if you retain the sins of any, they are retained.
Obviously that is an attribute given to all who receive the Holy Spirit... That would encompass a couple hundred million or billions of Protestants...Likely a few Catholics as well...
