I think it was in 2008, while residing in Lourdes as a “permanent chaplain” (as they are called), living in the chaplains’ house far above the grotto, I was witness to all four FSSPX Bishops assisting at Holy Mass in the Underground Basilica of Saint Pius X. There were well over 20,000 pilgrims in attendance. To be specific, Bishop Richard Williamson was, of course, among them. Bishop Williamson is a Holocaust denier, particularly of the gas chambers. He should watch this video of this Jewess’ account of the gas chambers.
