Therefore if your enemy hungers, feed him; if he thirsts, give him drink: for in so doing you shall heap coals of fire on his head.
All Commentaries on Romans 12:20 Go To Romans 12
Jerome
AD 420
We are not to revile and condemn our enemy, as the world does, but rather we are to correct him and lead him to repentance so that, being won over by our good deeds, he may be softened by the fire of charity and may cease to be an enemy.
