Here is a parable about Christology by Catherine Keller from her book On the Mystery, Discerning Divinity in Process.
A man died. The people who knew him gathered to share memories. Finally a portrait was commissioned. But as generations passed the painting did not seem fine enough. The heirs of the portrait, who had become wealthy, created a new golden frame, immense, carved with motifs from the portrait and encrusted with jewels. People began to feel that the old portrait of that dark fellow with the haunting eyes pulled the effect down. As it began to peel from age, they extended the frame inward. One day the frame covered the whole canvas.
