I am intimately familiar with BRN. This is just simple nonsense. I feel obligated to share some information concerning Fr. Pfeiffer.
He arrived at my home without much notice a couple years ago and requested quarters and an altar at which to say Mass. I obliged because I have known him for nearly 20 years. I told him point blank that his message was not balanced and yet I also gave him money because he is a priest and I am myself a former cleric. At this particular visit, he attempted to convince me that the local pastor at the time--of the SSPX had almost joined him in his resistance stance. This was a gross exaggeration of an assumption.
The assertion that Fr. Zendejas and +Williamson and His Excellency's non-profit in the US was created to take away anything from Fr. Pfeiffer is like saying lightning exists to clear arid forests and destroy the landscape.
One may happen as a result of the other, but it is not the primary reason.
Fr. Pfeiffer's penchant exaggerations are an unfortunate indicator of his mind; it is unbalanced and he is as well. We ought to pray for him to come to his senses and stop creating enemies.
