No analogy can be pushed too far, yet I believe the Church and Christianity can learn from Eustace's experience. Perhaps not all our accretions are bad, but in order to discern which are the good ones and which are the bad, we may need to submit the Church and Christianity to the same painful process. Yes, it hurts. But when we have allowed the accretions to be stripped off, we can bathe in a refreshing, cooling, cleansing pool and begin to recognize the better part of ourselves as the people of God who follow in the way of Jesus.
There's something beautiful about the bare altar, the empty aumbry, and the darkened vigil light. They allow us to see the unadorned structure on which the rest is built. Let's not be in too much of a hurry to cover it up. Sometimes less is more.
