Book excerpt: Devin Rose was raised atheistically but underwent a radical conversion to Protestant Christianity before ultimately becoming Catholic. This book was written after ten years of reflection and dialogue with Protestants and Catholics on the key issues that divide them. Rose presents a series of intelligible and compelling arguments for the Catholic Church's claim to be the Church that Christ founded. He considers the strongest Protestant responses to his arguments and offers straightforward rebuttals to them. The papacy, Ecumenical councils, the canon of Scripture, the Protestant Reformers, and the sacraments are just a few of the many topics covered in illuminating detail. Catholics will learn to defend their faith, and Protestants will be challenged to answer the toughest questions about the roots of their beliefs.
