Theonomy
Theonomy, from theos (god) and nomos ( law), is the idea that Mosaic law should be observed by modern societies. Theonomists reject the traditional Reformed belief that the civil laws of the Mosaic Law are no longer applicable. This idea is not to be confused with the idea of "theonomous ethics" proposed by Paul Tillich.
