Have you read The Bible? I presume on the promises of God. And a Catholic priest has a lot of hutzpah telling someone anything about playing God. I can go directly to my Father in Heaven for forgiveness, and don’t require a Catholic Priest for go between ... or Mary the Mother of Jesus ... or Creflo Dollar, etc.
Have you read John 20:23 where Christ gave his disciples the authority to forgive sins? Was this authority just granted to them and lost when they died or is it possible that it was passed down to those who took their place?
