 Because come on in, the water's terrible. The Catholic Church is a lot like Noah's Ark. It can be messy and difficult, and there are irritating fellow passengers, and it can be tumultuous and disappointing and exhilarating and beautiful, and all of those things all at once. But don't let that stop you, because, of course, this is the church Jesus established, and he's in charge, and we're like all those animals on the ark.
