In the past few hundred years, the Bible has been under severe attack by scientific and philosophical skeptics of all sorts. In this scientific age the most-attacked book of the Bible has arguably been Genesis, particularly the first 11 chapters. Long-age geology, big-bang cosmology, secular archaeology, liberal theology, and philosophical attacks on miracles in the Bible have deceived many people to believe that the Bible is not true and therefore cannot be trusted.
One of the major attacks on the Bible in the past three hundred years has been directed against Moses and his authorship of the Pentateuch, the first five books of the Old Testament (Genesis–Deuteronomy). Such attacks on these foundational books of the Bible come both from non-Christians as well as professing Christians.
Seminary courses, theology books, introductions to the Pentateuch in Bibles, and the secular media have promoted the man-made idea that Moses did not write the Pentateuch (also known as the Law or Torah). Instead, it is claimed that at least four different authors (or groups of authors) wrote various portions of these books over many centuries and then one or more redactors (editors) over many years combined and interwove everything together into its present form. For example, one translation of the Bible we surveyed said this in its introduction to the Pentateuch:
Despite its unity of plan and purpose, the book is a complex work, not to be attributed to a single original author. Several sources, or literary traditions, that the final redactor used in his composition are discernible. These are the Yahwist (J), Elohist (E), and Priestly (P) sources which in turn reflect older oral traditions.
