..,The book follows the chronology of the conference. After a presentation by Professor Jacques VIER, Monsignor LEFEBVRE takes the floor by stating the topics discussed, on the evolution of the Church and the crisis of Teaching and Magisterium, the priesthood and aspects of faith. There is also a long passage justifying the celibacy of priests and its reasons.
