Supersessionism, also called replacement theology, is a Christian doctrine which asserts that the New Covenant through Jesus Christ supersedes the Old Covenant, which was made exclusively with the Jewish people.
In Christianity, supersessionism is a theological view on the current status of the church in relation to the Jewish people and Judaism. It holds that the Christian Church has succeeded the Israelites as the definitive people of God or that the New Covenant has replaced or superseded the Mosaic covenant.
From a supersessionist’s point of view, just by continuing to exist outside the Church, the Jews dissent. This view directly contrasts with dual-covenant theology, which holds that the Mosaic covenant remains valid for Jews.
Supersessionism has formed a core tenet of many Christian Churches for the majority of their existence. Christian traditions that customarily have championed dual-covenant theology (including the Roman Catholic, Reformed and Methodist teachings of this doctrine) have taught that the moral law continues to stand.
Subsequent to and because of the Holocaust, some mainstream Christian theologians and denominations have rejected supersessionism.
The Islamic tradition views Islam as the final and most authentic expression of Abrahamic prophetic monotheism, superseding both Jewish and Christian teachings. The doctrine of tahrif teaches that earlier monotheistic scriptures or their interpretations have been corrupted, while the Quran presents a pure version of the divine message that they originally contained.
