I've recently been accused of mis-interpreting Bishop Williamson and 'jumping in the middle' of his EC354.
Specifically this portion contains an error - can you pick it out?
Thus where Archbishop Lefebvre saw clearly that the Conciliar Church, by losing all four marks of the Catholic Church (one, holy, catholic, apostolic), was not the Catholic Church, Bishop Fellay (Superior General since 1994) and Fr Nicholas Pfluger (First Assistant since 2006) insist today that there can only be one Church, and so the Conciliar Church is the Catholic Church. Naturally then, where the Archbishop kept the SSPX at a safe distance from the Conciliar Church, Bishop Fellay and Fr Pfluger want to abolish that distance and bring the SSPX back within that Church which is Conciliar. And neither Bishop Fellay nor Fr Pfluger will feel Catholic until they have achieved that end.
The first is that Bishop Williamson is ascribing a belief to Archbishop Lefebvre. This is simply one of the tactics used - to ascribe to another a belief that he (Bishop Williamson) wishes to impart upon his readers.
