We have domesticated God's transcendence. We often learn about God at about the same time as we are learning about Santa Claus; but our ideas about Santa Claus change, mature and become more nuanced, whereas our ideas of God can remain at a rather infantile level.
Whatever conclusions we reach about the reality of God, the history of this idea must tell us something important about the human mind and the nature of our aspiration.
We constantly have ideas and experiences that go beyond what we can say or know. Most often these are expressed in art, in painting, in music. Music, everyday confronts us with a form of knowing that doesn't depend on words.
Religious ideas and practices take root not because they are promoted by forceful theologians, nor because they can be shown to have a sound historical or rational basis, but because they are found in practice to give the faithful a sense of sacred transcendence.
I had tried, as I thought as a nun, to open myself to God and God seemed totally uninterested in me. The heavens remained closed and opaque. I now realize, of course, that I had a very, very inadequate idea of God. I was expecting clouds to part, a little sort of whisper in my ear, and of course, that's not what God is. God is not another being; we are talking about something much more profound.
