After being repeatedly rebuffed in his attempts to re-evangelize Calvinist Protestants who would not listen to Catholic preaching for fear of reprisals, St. Francis turned to writing leaflets and inserting them into copies of his sermons, which he then posted on walls, slipped under doors and handed to whomever he could. Four years later, almost 72,000 had returned to the ancient Catholic Faith! These tracts have been compiled into a book and given the title The Catholic Controversy. What reviewers say about this book: "If you ever had any doubts about the truth of the Roman Catholic Faith, read this book. Saint Francis will set you straight!"
