Doesn’t matter if they go confess or not, because if they continue to live as a “married couple”, they are in a continual state of sin, which shows there is no contrition. Sins can’t be forgiven if there is no contrition, it doesn’t matter whether you go to a priest and confess them or not.
I don't plan on sitting in judgment on ANYone. It reminds me of Jesus' sermon about the "boulder" in MY eye.
Thank goodness God is our judge and not....
