You can understand why then the Jews at the time of the early church were not all too happy with this new Christian off shoot from their faith. All of their traditions and teachings, all their customs of sacrifice and temple worship, all the prophecies and promises for the nation and its future, all its wisdom and all its spiritual benefit drawn up from the Hebrews to their mind was being hijacked by Paul and the Apostles and channeled into a focus upon one person, Jesus of Nazareth. You can image this would make them quite resentful and jealous. Still does to a large extent. To this we, the Christian plead, guilty. We lay claim to not only to the New Testament but all the writings of the Old Testament. We treasure the Scriptures as accounts of God's preparing history directing all people into His salvation... into His good news and that news is all about Jesus Christ.
