This book is for the curious and thinking Protestant who is interested in what the Catholic idea of the church really is. Making no attempt to browbeat the reader into agreeing with that idea (even if it were possible), the book tries to address the common problems and misconceptions most Protestants have about the Catholic Church: the papacy, church authority and Tradition (vis à vis the Bible), the nature of church unity, and its claim to being universal (why there can be only one true church of Christ).
