That statement however is not a judicial action by the Pope.
One of the things that extremely difficult for most Catholics to understand is that their legal system is not like political legal systems.
Its origin is theological. It is therefore interpreted and applied in a way that differs from civil legal codes.
“That statement however is not a judicial action by the Pope”
It reads to me that the Pope was commenting on the very act of procuring an abortion DOES NOT NEED A PAPAL JUDICIAL ACTION for excommunication. It is automatic from the very moment the politician made up his/her mind to vote for it.
Since my quite simple research has proven the current excommunicated status of ALL PRO ABORTION politicians, I will change my statement to “The Pope needs to instruct his bishops to refuse all sacraments except confession to these abominations.”
This fact appears to be the exact opposite of what the original poster was claiming regarding excommunication for politicians.
