Most Christian views on the Old Covenant hold that it has been superseded or abrogated and replaced with the New Covenant which is the only one of the biblical covenants that remains valid today. Dual-covenant or two-covenant theology is unique in that it holds that the Old Covenant or the Bible's Law of Moses remains valid for Jews while the New Covenant only applies to non-Jews or gentiles. This theology appears to conflict with the Catholic and Orthodox Christian doctrine of extra Ecclesiam nulla salus and the Protestant doctrine of Solus Christus.
