In spoken form via you tube video by a Traditional Catholic....
An encyclical on the Doctrines of the Modernists. This has been officially out of print for years. One would think that it, and its author, never existed. Fortunately, it was written in a manner which is ideal for spoken-word production. It is clear, forthright, concise, descriptive, it is like a mountain stream in a desert, with a reputation of miraculously curing spiritual blindness.
