I recall reading that Catholics have not added to the books of the bible; it was Luther who excluded some books because it did not fit his theology. I mentioned this to a Lutheran friend during a discussion. He was very surprised. So, I wanted to get the details before I speak to him again. Can you help?
The canon of the Old Testament was fixed in the year 382 under Pope Damasus and it has remained unchanged in the Catholic Church to this day. During the Reformation, Protestants removed seven books from their Old Testament canon primarily due to doctrinal reasons.
