When there were two / three Popes in the 1500’s (anti popes), did the same group of bishops elect them. I have a friend who has made a statement that the Pope elected after the one who came back after being spoken to by St Catherine died shortly after returning to Rome. Another bishop of Rome (Pope) was elected (largely due to duress) and a short time after that the same folks decided to elect anther one because they didn’t like what the first one was doing. …he claims this as evidence the Catholic Church is not the true church and has no apostolic succession.
I told him there is a perfectly logical explanation and likely they were not the same cardinals or “electoral committee” even if the Italian cardinals abstained from the vote. Does anybody have some historical evidence I can show. I understand there was a lot of questionable things happening in the Church at that time and would like to be able to show him the truth (Historically and what both sides of the argument believe). Seems like any time a bring up the Church he always reverts to this issue this is a major stumbling block for him.
