Life Siebel was raised an Evangelical Protestant and converted to Catholicism a short time before Vatican II. As a Conservative Christian, he became involved with the Catholic Traditionalist movement resisting the adoption of the Modernist ideas into Catholicism as a result of the Aggiornamento and Vatican II. Controversy The French Traditionalist priest, George de Nantes wrote in his The Catholic Counter-Reformation in the XXth Century, #220, June 1989, page 20, para 1 & 2 that Wigand Siebel and his followers teach that, with the Modernist apostasy, the Catholic Papacy has ceased to be or that it has come to an end, a teaching which contradicts Catholic teaching that is strongly emphasised.
