The authorship of the Pentateuch has been the subject of great controversy among professing Christians since Spinoza introduced "higher criticism"of the Bible in the seventeenth century. The "documentary hypothesis,"which developed from his work, is that Moses did not write the Pentateuch, as most scholars in Judaism and the church until that day believed. Instead, it was the product of several writers who lived much later than Moses. A redactor (editor) or redactors combined these several documents into the form we have now. These documents (J, E, D, P, and others) represent a Yahwistic tradition, an Elohistic tradition, a Deuteronomic tradition, a Priestly tradition, etc.5
The evidence that Moses wrote the Pentateuch is conclusive if one believes that Jesus Christ spoke the truth when He attributed authorship to Moses (Matt. 19:8; Mark 7:10; Luke 18:29-31; 20:37; 24:27; John 7:19). Jesus Christ did not specifically say that Moses wrote Genesis, but in our Lord's day the Jews regarded the Pentateuch (Torah) as a whole unit. They recognized Moses as the author of all five books. Consequently they would have understood what Jesus said about any of the five books of Moses as an endorsement of the Mosaic authorship of them all.6
