Bede

He who makes a pledge for a stranger will be punished by the evil. The sense of the letter is at hand. But he is a stranger from the lot of saints who neglects to correct his sins by repentance; and whoever grants the grace of communion to such or promises eternal life, because he has made a pledge for a stranger, surely renders himself deserving of vengeance before the strict judge.
