The document discusses the author Dan Billingsly's view that the gospels of Matthew, Mark, Luke, and John (MMLJ) should be considered part of the Old Testament rather than the New Testament. Billingsly argues that during the time period covered by MMLJ, Jesus was fulfilling his role as the final Old Testament prophet sent only to Israel, and his teachings were focused on the Old Testament law rather than establishing the New Testament. Traditional interpretations that view MMLJ as part of the New Testament are criticized.
