Supersessionism

Supersessionism is the Christian theological belief that Christianity is the fulfillment of Biblical Judaism. In its more radical form, generally termed "replacement theology", supersessionism, maintains that the Jews are no longer considered to be God's Chosen people in any sense. The Church is the People of God and the New Israel, to whom alone the promises of God belong. The more general understanding of this view in a milder form is therefore that Jews who deny that Jesus is the Jewish Messiah fall short of their calling as God's Chosen people, but God has not entirely cast them off as His Chosen, to whom the promises also belong.

According to the ordinary reading of the New Testament and the consensus of the majority of Christians from the 1st century to this day, the authority of the kingdom of God had been wholly taken away from the Jews in the 1st century and given to the leaders of the Gentiles and Jews in Christ long before the Council of Jamnia. Stephen the first martyr for Christ testified to the Sanhedrin this fact by the Holy Spirit:

"Ye stiffnecked and uncircumcised in heart and ears, ye do always resist the Holy Ghost: as your fathers did, so do ye. Which of the prophets have not your fathers persecuted? and they have slain them which shewed before of the coming of the Just One; of whom ye have been now the betrayers and murderers: Who have received the law by the disposition of angels, and have not kept it." Acts 7:51-53 KJV

The Apostle Paul himself testified that the Jews are no longer the arbiters of Holy Scripture, but instead that Christian leaders are to be accounted as "the stewards of the mysteries of God". See the testimony of the following scriptures of the Bible:
