During the crisis and confusion of these prophesied last days true Catholics must avoid, not only the counterfeit Catholicism of the "left" (the new religion of Vatican II) but also the equally counterfeit Catholicism of the "right," represented by those who believe the current situation in the Church gives them carte blanche to become, by hook or by crook, priests and bishops -- in defiance, not only of Church law, but even immutable divine law, which neither "epikeia," a "state of emergency," or "supplied jurisdiction" can successfully dispense the would-be priest or bishop from.
Sacred Scripture, Sacred Tradition, the Doctors of the Church, and the Magisterium all consistently teach that the Church's clergy must always and necessarily possess a divine mission and authorization in order to legitimate, validate, and make salvifically efficacious their priestly activities.
Since the clergy of such unauthorized groups as the SSPX, SSPV, CMRI et al, lack such a mission, these men are therefore NOT priests of the Christ's one, holy, Catholic, and apostolic Church, but merely the priests of various man-made traditionalist sects. As such, they are off-limits to true Catholics, upon peril of our eternal salvation. Our most controversial CD ever!
