In this interview, Bishop Williamson discusses the path that led him to his current position. He asserts that the modern world's authorities, including the contemporary Vatican, are disciples of the French Revolution, freemasonry, and moral relativism...trends whose ultimate source is satanic. (For more on the sources of this "contamination," see my interview with Michael Hoffman.)
We also touch on the "sacred" Holocaust and 9/11 narratives, both of which play a foundational role in conditioning populations to accept the rule of the satanic/demonic. (Bishop Williamson's problems with the official Catholic authorities stem in part from his challenging such official narratives; he is on record saying that 9/11 was an inside job and that the Holocaust is a false religion based on a grossly inflated death toll and false tales of hydrogen cyanide gas chambers – claims that led to his being fined $16,822 by a German court.)
The interview also contains a fair bit of interfaith dialogue. I note that the traditional Catholic worldview, as summarized by Bishop Williamson, is almost identical to the Islamic one. The major exception, as the Bishop forcefully notes, is the Catholic belief in the holy trinity, which Islam rejects.
