… religion is more than a theism. It is a bundle: a theory of the world, a community, a social identity, a means of finding peace and purpose, and a weekly routine. Those, like me, who have largely rejected this package deal, often find themselves shopping à la carte for meaning, community, and routine to fill a faith-shaped void. Their politics is a religion. Their work is a religion. Their spin class is a church. And not looking at their phone for several consecutive hours is a Sabbath.
