Images of the Holy easily become holy images - sacrosanct. My idea of God is not a divine idea. It has to be shattered time after time. He shatters it Himself. He is the great iconoclast. Could we not almost say that this shattering is one of the marks of His presence? The Incarnation is the supreme example; it leaves all previous ideas of the Messiah in ruins. And most are "offended" by the iconoclasm; and blessed are those who are not. But the same thing happens in our private prayers.
All reality is iconoclastic.
...
Heaven will solve our problems, but not, I think, by showing us subtle reconciliations between all our apparently contradictory notions. The notions will all be knocked from under our feet.
