These CHARTS are the best. Get them all.

Were all biased anyway. The question is which bias is the best bias. Catholics or anyone who "may not benefit as much" from this tool should wonder why not? I don't think God wrote a book hard to be understood. If you are a Catholic, Charismatic, or of the "Orthodox" persuasion, and you cannot "benifit as much" from this chart due to "bias", then perhaps you need to explore the differences between what makes a Christian different from a Catholic. These are not merely terms. A "Christian" is not an umbrella that encompasses a vast majority of mainline denominations or cults or movements or sects, as many people would have others to believe. God in His word tells us who are His. It would be best for folks to check it out. (Jn.1:12; 3:16; Eph.2:8 etc.)----anyway. As the Charts are a great series I personally own three of the set or series, and they are outstanding.

Another good example of useful charts

This book of charts is part of a series covering the Old Testament, the New Testament, Church History, Christian Doctrine, Philosophy, etc.
