This is why, when I say that the Church “moves through history,” I mean that she moves slowly through history, like a ship through open waters. Everything about her is slow, and takes time. For while she is always capable of turning (and even of turning again if she overcorrects) she is also huge and hulking, so that she must be mindful of her own momentum, which is strong enough to take her off course if the helmsman doesn’t steer with prudence.
