I wish I had the answer for you, I am for excommunicating them myself. Yes, I am a Catholic - a real practicing one! LOL
One of the things we’re overlooking is that there is a difference between a private individual who needs work on his attitude to abortion and a public figure, a leader, who actually makes decisions on the issue, supports it, promotes it and passes laws permitting or encouraging it.
Perhaps the first person, the private individual, needs lots of preaching and lots of prayer, and obviously the priest cannot be expected to quiz every person who comes up for Communion. But it is a scandal for a known public figure, a politician whose self-proclaimed views and actions are known to everyone and known to be in conflict with the teachings of the Church, to be admitted to Communion.
I am hoping some bishop somewhere will have the courage to tell Biden that he may not go to Communion in his diocese. Biden’s bishop, Saratelli, is very forthright on the issue in genearl, but he told his priests that they were not to make the decision on withholding Communion. Maybe this means that he himself is going to forbid Biden to go to Communion, after a due warning to repent?
