God’s holiness
The rabbi put the question to my friend directly: Do Christians believe that God is holy?" My friend was initially taken aback; she thought of the popularity of the hymn "Holy, Holy, Holy," and of her love of passages in Exodus, Isaiah and Revelation that emphasize the holiness of God. She recalled the passage in the Lord's Prayer where we indicate that God's name is hallowed. "What is the rabbi really asking?" she wondered to herself.
