We say now that we follow a faith, as if it walks before us. We say that we are of a faith, as we are of our hometown, or of color—as a thing that forms and shapes us so deeply that we cannot be rid of it. If so, then I am faithful (that word my best guess).
The word was made flesh; we heard it not. In the unconscious occupation of our praying minds sometimes we get a sense of it, like awakening from a sweet dream.
