I take it that the Hebrew Scriptures are what Christians reference as the Old Testament. Please define "Greek Scriptures" since the term apparently has several meanings including a new and often erroneous Jehovah Witness translation completed and published in 1961 (Jesus was a god as opposed to God; Jesus was impaled not crucified, inter alia or some or all of the New Testament). You know what you mean. I don't know what you mean. Please clarify.

See the rendition in Acts of the early Church leaders coming to Jerusalem in the 50s AD to discuss and determine a question posed by Paul as to whether adult male Gentiles had to be circumcised in order to become Christians. The answer of Peter was ultimately that circumcision (and therefore Judaism) was unnecessary for a Gentile man converting to Christianity. This did not mean that it was forbidden. I have no source but I believe that the Sanhedrin saw to the expulsion of the Christians from Temple worship at or about that time.

As to creation of Christianity, see the Peter passage in Matthew 16: 13-20. Jesus was a Jew which I do not dispute but He did build His Church upon Simon bar Jonah, renaming him Peter.

You appear to be correct and I appear mistaken as to Josephus but I am not sure how that affects the underlying question.

The Bible is written in 3 languages. Hebrew (with parts of Daniel in Aramaic) is found in the front 3/4. The last 1/4 was written in Greek. With the possible exception of the books of Luke and Acts, all 66 books were written by native Hebrew speakers, containing a single unified message. There is no such thing as the "Old Testament" or the "New Testament" - those are man made categories invented for theological reasons - one of which is the theology of Supercessionism - also know as Replacement Theology.
