St. John Damascene ca. 676-749
[Muslims] accuse us of being idolaters, because we venerate the Cross, which they abominate. And we answer them:
‘How is it, then, that you rub yourselves against a stone in the Ka’ba and kiss and embrace it? …Let it be Abraham’s, as you so foolishly say. Just because Abraham had relations with a woman on it or tied a camel to it, you are not ashamed to kiss it, yet you blame us for venerating the Cross of Christ by which the power of the demons and the deceit of the Devil was destroyed.’ (The Fount of Knowledge: On Heresies, 101)
