What is "supersessionism"

n. (context Christianity English) The belief not merely that Judaism has been supplanted by Christianity, but that the covenant between God and Israel as His chosen people has been abrogated.

Supersessionism, also called replacement theology or fulfillment theology, is a Christian 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Christian Church has succeeded the Israelites as the definitive people of God or that the New Covenant has replaced or superseded the Mosaic covenant.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 reaches its culmination in Islam and the doctrine of Tahrif, which "sees itself as the final successor to and the completion of the Abrahamic faith tradition of ethical and prophetic monotheism."

Supersessionism formed a core tenet of the Church for the majority of its existence, and it remains a common assumption among Christians and Muslims. Subsequent to and because of The Holocaust, some mainstream Christian theologians and denominations have rejected supersessionism.
