I certainly don’t agree with the middle-of-the-road approach the RCC is apparently starting down on this, but, I wonder, if someone is engaging in adultery, fornication, etcetera, should any church tell them that they can never come back to church and attend service(s) to listen to the message even if they have not repented?
If somebody repents and asks for forgiveness as indicated by Matthew 18:21-22, as opposed to going into “womanly indignation” mode, insisting that their sinful practice is just a “little old sin” as opposed to evil, then Jesus used the expression to forgive them seventy-seven times.
But I don’t see unrepentant sinners necessarily taking an interest in a church again after being confronted by a congregation. After such a confrontation unrepentant sinners at least know that they aren’t fooling anybody.
