Archbishop Lefebvre did very well when he refused the agreement. "For what participation hath justice with injustice? Or what fellowship hath light with darkness? And what concord hath Christ with Belial? Or what part hath the faithful with the unbeliever?" (2 Cor. 6, 14-15).
From the author: “ An analysis of the evidence relating to an agreement between the Society of Saint Pius X and the Conciliar Church of Rome I seek to analyse the evidence relating to a possible agreement between the Society of Saint Pius X and the Conciliar Church. I conclude that many of the Superiors of the Society are prepared to enter into an agreement with the Conciliar Church, where that agreement is a practical agreement (only), without a doctrinal resolution and the terms of which would mean that the Society would be subject to the Conciliar Church. I conclude that the conduct of many of the Superiors of the Society in relation to a possible agreement with the Conciliar Church represents a staggering change from the Society’s principles and direction. I conclude that the position adopted by many of the Superiors of the Society in relation to such an agreement is contrary to the position of the Society’s founder, Archbishop Lefebvre.”
