As with Guerrilla Apologetics for Life Issues, this book teaches how to frame the discussion, not merely respond to innumerable questions until your opponent is worn out. In fact, he teaches how to turn their question into our question.
A great jumping-off point for a beginning apologist, or handy pocket guide for a seasoned apologist. It covers all the basic points of discussion, Purgatory, the doctrine of "faith alone is necessary for salvation, the doctrine of "Scripture alone", the Papacy (with a handy list of every pope since St. Peter), divorce, the saints, the Blessed Mother, and the Eucharist.
Once you get these basic points down, or become proficient at looking them up in this user-friendly book, you can correct 90% of Protestant misconceptions about Catholicism.
Archbishop Fulton Sheen once said, "most people don't reject Catholicism, they reject what they misinterpret as Catholicism". Correct the misconceptions, and your job is done.
