All of us can understand institutional disenchantment. Institutions can be slow, plodding, dictatorial; they can both enable and shield wrongdoers. They frustrate our desires by asking us to submit to the will of others.

But institutions are also the only mechanism human beings know to perpetuate ideologies and actions. If books were enough, why have universities? If guns enough, why have a military? If self-governance enough, let’s get rid of Washington. The point is that if you want to do something lasting in this world, you will recall the wise words of French Catholic writer Charles Péguy: “Everything begins in mysticism and ends in politics.” Got a vision? Get a blueprint.

Spirituality is an emotion. Religion is an obligation. Spirituality soothes. Religion mobilizes. Spirituality is satisfied with itself. Religion is dissatisfied with the world. Religions create aid organizations; as Nicholas Kristof pointed out in a column in the New York Times two years ago: the largest U.S.-based international relief and development organization is not Save the Children or Care, it’s World Vision, a Seattle-based Christian group.
