Why was this book written? "Because modern Protestants have not only forgotten what Rome was, what she is, and what she will forever be; the most irreconcilable and powerful enemy of the Gospel of Christ," writes Chiniquy.

This is the life story of Pastor Chinquy, who was a priest in the Roman Catholic church for 25 years. Though he dedicates this book to the Bishops, Priests, and people of Rome, he writes, "the sophisms and errors of Romanism are discussed and refuted with a clearness, simplicity, and evidence, which my 25 years of priesthood only could teach me."

It is written in a kindly and Christian spirit, does not indulge in denunciations, and while speaking the truth, it does so in love.

This is the unabridged edition of over 600 pages.
