Note: There are a few historical errors in this presentation. First, St. Vincent Ferrer did not advise disobedience to the man who was pope, when he thought he was the pope. Rather, a council was held at Toulouse and St. Vincent spoke in favor of the Pope of Avignon, but after hearing the testimony and vote of the Council against the pope of Avignon, he abandoned allegiance to him and accepted the decision of the Cardinals gathered at Constance to propose a reunion by asking all candidates to resign.
Second, St. Vincent Ferrer was a greats saint, but a lousy police man, researcher and inquisitor. He believed what Cardinal de Luna told him without even the slightest doubt that his good friend was an utter self serving liar. Here we do not imitate or laud St. Vincent, but we can excuse him because unlike us, he does not have the internet to access all the documents, which in our present crisis prove 100% that Benedict XVI is the pope, and all who think otherwise do no have one document or fact to argue upon, they only weave gratuitous assertions of interpretations and out right lies against the teaching of the Church or the laws of the Church.
