In today’s Acton Commentary I explore “The Legalism of Political Christianity.”
This quote from Ernest Lefever (not included in the piece but which does appear in my book) represents the basic position well:
It is dangerous for any Christian body to identify itself fully with any specific political cause or order, whether the prevailing one or a challenge to it. In identifying with a secular power or agency, the church runs the risk of losing its critical distance and of subverting its prophetic function, its capacity to judge all movements and systems by universal Christian standards.
