On the Brink of Incarnation

From The Forbidden Image by Alain Besancon, speaking of differences between Judaism and Islam:

"Judaism always seems on the brink of Incarnation. That is why the Jewish people need the commandments from their God, to resist the temptation to make an image of him or to imagine him. In Islam, the image becomes inconceivable because of the metaphysical notion of God. As soon as proof of submission (Islam) to that God is given, the association (shirk) between God and any external notion of his essence, any person (as among Christians), and a fortiori any matter, is perceived with horror as an attack on unity, as a return to polytheism."
