I believe your religion teaches that your priests actually become God, to forgive your sins...Isn't that correct???
I think it’s that priests are given the authority of God to forgive sins, but that the authority comes from God.
Same thing with Lutherans, except for the fact that there are no priests, since Jesus is our only High Priest who makes intercession for us.
Whatever the case, when the pastor declares forgiveness of sins, it’s as if God himself has said so, because Jesus gave that power to the Church through the Apostles. (Not Roman church, the capital-C Church of all believers.)
Of course, I could be wrong re: what Catholics believe.
