An essential bulwark against intellectual and theological confusion, Fr. Jean-Baptiste Lemius's classic A Catechism on Modernism renders Pope St. Pius X's landmark 1907 encyclical Pascendi Dominici Gregis into a clear, systematic question-and-answer guide. Formally approved by the Holy See, this definitive work systematically unmasks what St. Pius X termed the "synthesis of all heresies"—exposing the subtle philosophical shifts, agnostic premises, and destructive biblical criticism aimed at eroding sacred dogma from within. Methodical, unyielding, and impeccably reasoned, this restored edition provides theologians, apologists, and faithful Catholics with an indispensable masterclass in Thomistic clarity and traditional Catholic doctrine.
