The Oratory Catechism was put together by Professor Doctor Wigand Siebel, professor in sociology at the University of Saarbrücken, Germany. It has 100 pages of questions and answers devoted to the End Times. It explains what it means to be a True Roman Catholic by clarifying the Apostasy of Pope and Bishops of the Roman Catholic Church.
Prof. Siebel Siebel was raised a Lutheran, but looking all his life for the Truth, even writing the first ever scientific study of the Truth.
Shortly before Vatican II he found the Truth in the Pillar of Truth, the Roman Catholic Church as St. Paul calls it. He was a hero of the German anti Vatican II resistance. He was for some time cooperator, later editor of the Saka-Informationen (1975-1982), the organ of faithful German Catholics. It was the most widely used periodical by Catholics who supported the thesis of the current vacancy of the Apostolic See, the so-called Sedisvakantismus in German. It was related to Prof. Siebels Oratorio of Divine Truth 9hence Oratory Cathechism) and his St. Petrus Canisius convent. Celebrities such as Gerd-Klaus Kaltenbrunner and Reinhard Lauth also wrote in the magazine.
Professor Siebel wrote a book on the difference between the Catholic Faith and the Conciliar faith, which makes him an expert to summarize the developments started by Vatican II is his Oratory Cathechism:
We present a pdf file of the second part of the book here, that deals with the changes in the unchangeable (!) Catholic Faith, that the archenemy of the Church, using the infernal current of modernism, has been forcing on the Catholics ever since Vatican II.
We wish the readers a fruitful reading, ad maiorem Dei gloriam!

Professor Siebel cannot be thanked better for his work than by praying for the rest of his soul.
