As some friends and I ate a picnic lunch, we fell into a rambling conversation about politics, real estate values in an earthquake zone and the virtues of sauvignon blanc over chardonnay. Then I mentioned offhandedly that perhaps I viewed something or other the way I did because I was a Christian. This revelation did not strike me as a big deal. After all, they had been talking about Buddhist meditation, Sufi parables and personal spiritual rituals.
