In this video, Bishop Athanasius Schneider addresses the question of attending sedevacantist churches when reverent Masses are not available. He emphatically states that it is never permitted to attend sedevacantist churches due to their schismatic nature and incompatibility with the Catholic Church. Bishop Schneider explains the distinction between sedevacantist groups and the Society of St. Pius X (SSPX), highlighting that the SSPX acknowledges the Pope's authority and prays for him in Mass, although they may struggle with obedience in certain matters amid the Church's crisis. The video sheds light on the importance of upholding the primacy of the Pope and adhering to the true doctrine of Christ while navigating the challenges of canonical submission. Bishop Schneider's insights provide clarity on this complex issue within the Catholic Church.
