A Biblical defence of the Catholic Faith. With a mastery of Scripture equal to that of the most committed Protestants, author David Armstrong shows that the Catholic Church is the "Bible Church par excellence," and that many common Protestant doctrines are in fact not biblical.
My father-in-law gave me this book and I've thoroughly enjoyed it and been challenged by it. The author is a Protestant convert to Catholicism and he writes in a scholarly, logical way on the main theological and practical differences between the two camps. I'm a long-time non-Catholic Christian who is now planning on practicing Catholicism, initially because I thought the differences weren't that huge (and really, they aren't) and I married a Catholic man and want our family to attend services together. Now I am appreciating the wealth of history and knowledge in the Catholic church and the fact that they emphasize the sacraments as physical, sensory acts that aid and represent intangible beliefs.
In most part, Protestants "stand alone on the word of God" (lyrics from popular childrens' B-I-B-L-E song? anyone?) for theological decisions where as Catholics acknowledge many other sources of wisdom (church tradition, writings that aren't included in the Bible, and revelations from God). This book sticks to Biblical arguments only (solo scriptura), as the author reasons that this is the only source Protestants recognize.
I'd recommend this thorough, well-referenced book to anyone interested in the big differences between Protestantism and Catholocism, no matter whether you practice either faith yourself.
As far as apologetic works go (as I have read quite a few at this point in my life), this book was pretty decent. I enjoyed all of the grounding which Armstrong did in tying Roman Catholic tradition to both the Scriptures and to the first Saints of the New Covenant era. The only thing which I didn't like about the work is that it seemed to be too focused on defending Catholicism against protestants, rather than making an overall case for the Roman Catholic approach to Christianity as a whole. The other issue which I had was that Armstrong tended to lean heavily on the CCC for authority more than I would have. The reason this is an issue is that protestants (whom Armstrong addresses frequently) don't see the CCC as an authority and this might unnecessarily water down an otherwise effective argument.
Very well written with references cited throughout and easy to understand. Ad a Catholic, this made my faith stronger and understand things better! Highly recommend!
