Yet he’s able to receive Catholic communion? I thought just one divorce and remarriage (let alone two!) would rule that out.
It is a little complicated, but the same rules don’t apply to non-catholics. Since he wasn’t married in the eyes of the Catholic church before, he isn’t divorced in the eyes of the catholic church.
My mom is Catholic, she was married before my father and got it annulled. She didn’t marry my dad in the church and they will divorce soon. I bet she will still take communion. They don’t enforce that.
