I recently purchased this book, "A Practical Commentary on Holy Scripture". It's a great introductory to Bible study, and most importantly it is Catholic. Based on the Douay Rheims Bible, each chapter tells a Bible story, with explanations of words and phrases, and explanations of the topics in the Scripture passage, showing the Catholic doctrines contained within Scripture.
I like the way the book is laid out; it is well written, simple to read. It is written to be read, if that makes sense. I don't mean it dumbs down, but neither is the reader assumed to be a theological expert.
It isn't easy to find a good solid Bible study, that is true to Catholic teaching. I'm working towards collecting the available Ignatius Bible study books, and the Navarre Bible series. If you have any recommendations, drop a note in the combox.
