In some ways, the answer to the question contained in the title of this book is pretty straight forward: If Jesus Christ is God and He founded a Church, then it cannot fall into error or fail to guide the faithful. Reflecting on the myriad of endlessly fracturing protestant denominations, it ought to be clear that this is not what Christ intended for His faithful. The Gospel was delivered ONCE for all the saints, then why so many Gospels? We have ONE Lord, ONE Faith, and ONE baptism-then whence comes such division? For those who simply want to discover that Church which is the one unerring TEACHER appointed by God, the object of the following pages is to show, in as simple and brief a manner as possible as plainly laid down in the scriptures received by Protestants themselves, that the Roman Catholic Church, and in her alone, are found the signs of Christ's Divine Protection. Christ has already provided believers a shelter from the tedious and interminable controversies into which Protestant disputants are always desirous to draw off the attention of their readers. That shelter is none other than the home of Holy Mother Church.
