Good Resource for Catholic Bible Study
What a fantastic resource! One-stop-shop for all things Catholic.
A veritable goldmine of reference materials; so great for apologetics! Dr. Scott Hahn (only ONE source on this site)is a great blessing for the Church and if you haven't read any of his work, I would urge you to, 'cause you are missin' out!
