To make bread or love, to dig in the earth, to feed an animal or cook for a stranger - these activities require no extensive commentary, no lucid theology. All they require is someone willing to bend, reach chop, stir. Most of these tasks are so full of pleasure that there is no need to complicate things by calling them holy. And yet these are the same activities that change lives, sometimes all at once and sometimes more slowly, the way dripping water changes stone.
