Query: Excellent theology primer

This book offers a good explanation of basic Catholic theology. In addition, he explains why the Catholic view is the only one that makes sense-- hence the "Sanity" in the title.The book is a bit boring at times, but this is probably done so that he will not lose people.Overall an excellent book. If you are interesting in learning a little about theology, I would read this book.
