It is hard to find examples of a pope exceeding even the near infinite authority of the papacy, but Pope St. Pius V managed when he tried to bind his successors as to rubrics which is a prudential and not a doctrinal matter. If that makes no sense to you, perhaps it will explain the state of confusion that leads you to defend the schismatic SSPX enemies of the Roman Catholic Church. Defending the traditional liturgy is NOT coequal to defending the SSPX. You have an idee fixe, BE, maybe its time to dismount your high hobbyhorse.
Do you claim to defend Holy Mother the Church, Pope John Paul the Great and Pope Benedict XVI from the virulent assaults of the excommunicated SSPX schismatics? If not, why not? If not, your basis for claiming to be Catholic?????
