In the parable of the wise and foolish builders, Jesus says, “Therefore everyone who hears these words of mine and puts them into practice is like a wise man who built his house on the rock. The rain came down, the streams rose, and the winds blew and beat against that house; yet it did not fall, because it had its foundation on the rock. But everyone who hears these words of mine and does not put them into practice is like a foolish man who built his house on sand. The rain came down, the streams rose, and the winds blew and beat against that house, and it fell with a great crash” (Matthew 7:24-27, New International Version of the Bible).

The rock is an important biblical metaphor. St. Peter’s name means “the rock,” and Jesus plays off the name by saying, “You are Peter, and on this rock I will build my Church.” Regarded as the successor of Peter, the Pope continues this rocklike tradition.” As result, neither doctrine nor liturgy is supposed to change. They are rocks.

The Dutch, however, are learning to build on sand using a Sand Motor, (the NPR story).

Unlike rock and its descendant, concrete, water passes through sand. You have to ask, What would Jesus do? Well, he’d want you to treat his planet well, and he was a creative storyteller, so what else, adapt the story: “Therefore everyone who hears these words of mine and puts them into practice is like a wise person who built his house on the sand. The rain came down, the streams rose, and the winds blew and beat against that house; yet it did not fall, because the rain passed through the sand. Everyone who hears these words of mine and does not put them into practice is like those foolish persons who build their houses on concrete foundations. The rain came down, the cracks widened, the streams rose, the winds blew and beat against that house. It fell with a great crash, its basement full of water.”
