I appreciate your answer but one of your fellow Roman Catholics has said the Holy Spirit does not select the pope.
How would you account for that?
The Holy Spirit doesn't elect a pope. Cardinal-electors do (although that wasn't always the process). They should ask for the Holy Spirit for guidance, but that doesn't mean they will actually listen to God's Will. Therefore, it is certainly possible for Cardinals to elect a false pope.
When such a "pope" universally teaches to the whole Church errors in matters of faith and morals that's a huge tip-off that he's not actually pope. Otherwise, God's Indefectible Church becomes Defectible. From a Catholic perspective, that can't be.
