that the "infallibility" of the Christian community extended to the pope himself, at least when speaking on matters of faith. Vatican I defined a twofold Primacy of Peter — one in papal teaching on faith and morals (the charism of infallibility), and the other a primacy of jurisdiction involving government and discipline of the Church — submission to both being necessary to Catholic faith and salvation.
