Excellent post, thanks Johannes.
Let us not forget that this great dogma of the Newchurch was supported by Bishop Fellay.
When Pope Benedict XVI implied that he would not have lifted Bishop Williamson's excommunication if he had known that the bishop was a h0Ɩ0cαųst denier, Bishop Fellay - instead of retorting that this is not a dogma of the Church - ordered Bishop Williamson to apologise to the Pope... isn't that just extraordinarily grave? Have the good priests of the SSPX sufficiently meditated upon this great betrayal???
