All monotheist religions go back to the Old Testament.  The Old Testament was accumulated over the course of 7000 years by oral Tradition, hand written copies when writing began, and printed copies from acceptable hand written manuscripts. Neither Jesus nor any of his Apostles wrote a word of the New Testament.  What we have are oral recollecitions of what some holy man said, and printed copies when the many manscripted copies were deemed to be reasonably authentic after some 1500 years of copying.  Is this what your religious beliefs rest upon?  Think about it.  Read Where Is God?  “Man shall not see me and live”(Exodus33:20) Go to the blog for “Where Is God William Jannen.”
