This book is in two parts. In the first I try to set out my reasons for being a Protestant; in the second are my reasons for rejecting Roman Catholicism. I make here a personal profession of faith, which binds nobody but myself. But it may be that the reasons for which I must be Protestant and cannot be a Roman Catholic will be of interest to to other Protestants who wish to be surer of their faith, and to those people who are attracted by some parts of Roman Catholic doctrine. I even dare to hope that some who have embraced the Roman Catholic faith will read what I have written, with their minds open to truth. I am a Methodist, a Protestant and a Catholic. I therefore pray that this book may tend, not to further division, but to the greater unity of the Holy Catholic Church, which is the Body of Christ and the People of God.
