Neonomianism in Christian theology, literally meaning "new law," is the doctrine that the Gospel presents a new law, the requirements of which are faith and repentance. This view is most often associated with the theology of Richard Baxter (1615-1691).

Opponents believe neonomianism changes the free Gospel offer into an understanding of salvation by works; i.e., humanity is not saved by Christ but by their obedience to Christ through their faith and repentance.
