2:10. And to whom you have pardoned any thing, I also. For, what I have pardoned, if I have pardoned any thing, for your sakes have I done it in the person of Christ:
I also… The apostle here granted an indulgence, or pardon, in the person and by the authority of Christ, to the incestuous Corinthian, whom before he had put under penance, which pardon consisted in a releasing of part of the temporal punishment due to his sin.
In Catholicsim we belive the preist have the same authority.
