VATICAN––Members of the Society of St. Pius X have stormed the internet and radio waves in violent protest against the upcoming canonization of Pope Simon Peter I. The backlash was worse than expected by the Holy See, and the protesters have not pulled any punches. One commentator on a popular tridentine website morecatholicthanthepope.com wrote, “This is the guy who denied Christ three times in one night, and now they want to canonize him? This isn’t the way Christ instituted the Church. This man is not an example to me or my 14 children.”
An SSPX blogger accused the former Pope, who was martyred for his faith in the First Century, of liturgical abuses, saying, “Christ was crucified head-upward. That is the pattern He established. Then this Peter guy comes along and decides he wants to be crucified upside-down.”
Some have even accused Peter, born Simon, son of John, of heresy in his famous debate with Paul regarding circumcision, while others claim his attitude toward the “circumcision party” was not true heresy but an exaggerated ecumenism.
Pope Francis commented: That is it! No more canonizations of popes for my Papacy, and if they try to canonize me after I am gone, I will come back and excommunicate all those involved!
