When the Reformation became established, one of the things that was a question between Catholicism and the Reformation traditions was whether there was a hierarchy of being. If you look at Thomas Aquinas, for example, you have hierarchies of angels and all the rest of it, and hierarchies even of saints and then subsaints - people who aren't quite there, that sort of thing. The Reformation rejected all of that and created a new metaphysics, in effect, that is not hierarchical.
