Way to a Christian Virtue

From Nietzsche, Mixed Opinions and Maxims (his sequel to Human, All Too Human, quoted from The Portable Nietzsche, p. 66):

Way to a Christian virtue. Learning from one's enemies is the best way toward loving them; for it makes us grateful to them.

What a great comment not only on loving one's enemies, but on the Old Testament command to welcome the stranger (foreigner) -- and then, of course, on our current discussion on immigration and the recent Arizona law (which just yesterday was put on hold by a federal judge).
