In Christianity, the abrogation of Old Covenant laws is the belief that the entire Mosaic or Old Covenant as abrogated in that all of the Mosaic Laws are set aside for the Law of Christ. While most Christian theology reflects the view that at least some Mosaic Laws have been set aside under the New Covenant, the belief in total abrogation of the Old Covenant is a minority belief.
Individuals who believe that Old Covenant laws have been completely abrogated are referred to as antinomians by various Christian traditions, such as the Methodist faith, which teaches that the moral law continues to be binding on the faithful.[1][2]
In John Wesley's day "cheap grace" went by the fancier name "antinomianism," which literally means "against the law." Antinomianism insists that if you are saved by faith and not by works, then works are irrelevant. We do not need to be righteous ourselves because we are covered by Christ's righteousness. Our hearts and lives do not need to be changed as long as we have faith in Christ. "The imagination that faith supersedes holiness," Wesley wrote, "is the marrow of antinomianism." ("On the Wedding Garment," 18).
