Why I Think Moses Wrote Deuteronomy
The logic behind the idea that Moses could not have written Deuteronomy is simply because it’s too accurate. As its author, Moses would have prophetically spoken of things that would happen 900 years later. If our assumption is that prophecy doesn’t occur, Deuteronomy must be a later composition. If we are going to accept the Mosaic authorship of Deuteronomy we will need to be open to miracles or at least vast coincidences.
