Friend: thank you for your post. Yes, a Pope can go wrong in his pontificate. Pope Leo XIII and cardinal Manning went over this: is it possible for a pope to go wrong in his pontificate. Did Our Lady not say to Sister Lucia, 1931, Pope XI did not heed God's request to consecrate Russia? She did refer to pope and then said, Pope Pius XI would be like King Louis XIV, dethroned, for not consecrating France to the Sacred Heart. And he was beheaded. Without the Pope the Church was beheaded.
