Archbishop Lefebvre
That Conciliar Church is a schismatic Church, because it breaks with the Catholic Church that has always been. It has its new dogmas, its new priesthood, its new institutions, its new worship, all already condemned by the Church in many a docuмent, official and definitive.... The Church that affirms such errors is at once schismatic and heretical. This Conciliar Church is, therefore, not Catholic. To whatever extent Pope, Bishops, priests, or faithful adhere to this new Church, they separate themselves from the Catholic Church...
Why does SSPX want to rejoin a schismatic Church ?
