Supersessionism

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Christian Church has succeeded the Israelites as the definitive people of God or that the New Covenant has replaced or superseded the Mosaic covenant.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.

Islam also views itself as superseding the Christian faith with its 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.

The word supersessionism comes from the English verb to supersede, from the Latin verb sedeo, sedere, sedi, sessum, "to sit", plus super, "upon". It thus signifies one thing being replaced or supplanted by another.

The word supersession is used by Sydney Thelwall in the title of chapter three of his 1870 translation of Tertullian's Adversus Iudaeos. (Tertullian wrote between 198 and 208 AD.) The title is provided by Thelwall; it is not in the original Latin.
