But it should be said that nothing in the New Testament is attributed to Jesus as a writer, it's more like a biography. And the books about Moses aren't written by the Moses person either, it would be very strange for him to say things like "he was born on..." and especially "he died then and there and afterwards...". In fact it has been established that the five Biblical books of Moses are themselves collections of texts spanning generations and which are even mutually exclusive and internally inconsistent. So the only factual writer (or rather illiterate narrator whose uttered words were written down directly or at a later date according to hearsay) among these is Mohammad. Whether such dictation is divinely influenced or not remains a matter of faith alone.
