The Mosaic authorship of the Pentateuch is a view that understands Moses to be the main author of the Pentateuch (i.e. the first five books of the Bible). This belief has received criticism, mostly in the last 200 years, yet remains supported by both Scripture and early church tradition. The conclusion is not that Moses wrote all of the Pentateuch, but that he had a major hand in not only its writing and development, but even its composition (i.e. how it was put together).
