That was a rather gross case. And it did depend on a clear idea of who’s an enemy.
The gospel will cut through this Gordian knot with the uncomfortable revelation that we are ALL the enemy, but the One we’ve been fighting has offered a gracious truce beyond our possible imagination.
This is not an “ism.” It has some elements of religion but goes beyond where religion goes (with religion you are polishing up something that is considered fundamentally okay). Modern political conservatism does not embrace the mercy side very well. Liberalism has attempted to do that, but they have a silly putty “God” with no standards so nothing definite can ever be produced.
