In his autobiography Joseph Turmel (1859-1943) has left an intensely personal account of his struggles to reconcile his Catholic faith with the results of historical-critical methods as those impacted biblical exegesis and the history of dogma. Having lost his faith in 1886, he chose to remain as a priest in the Church, even while he worked to undermine its teachings. He did so initially in writings published under his own name and, as his conclusions became increasingly radical, under a veritable team of pseudonyms. He was excommunicated in 1930.
His account of his life is less a discussion and defense of his ideas than it is a moral justification of his conduct. Turmel is associated with the left wing of Roman Catholic Modernism along with Albert Houtin, Marcel Hebert, and Felix Sartiaux
