Of course, this isn’t a matter of infallibility at all.
The Church does not teach that the Pope is protected by the Holy Spirit from misjudging the character of people, or making unwise appointments. JPII did all those things. He praised the monster Maciel Marcial (Or was it Marcial Maciel?) as a shining example to youth. He appointed one horrid bishop after another.
The latest buzz is that “the Pope doesn’t want culture warriors” (as bishops). Translation: The Pope doesn’t want Catholics.
What Catholic pope would not want Catholics?
