The Bible teaches that Moses wrote the first five books of the Old Testament. However, in the 19th century, Julius Wellhausen introduced the Documentary Hypothesis and many scholars believe, conclusively proved Mosaic authorship of the Pentateuch was false. This theory is one of the most influential theories taught in colleges and seminaries and has destroyed the faith of many Christians around the world. At a conference hosted by the Waialae Baptist Church, Pat examined this theory and presented a case for the Mosaic authorship of the Pentateuch.
