You might call the pair of stories something like, ‘On Finding the Jesus You Thought You’d Lost’. And if that is the message of these two passages, maybe Luke is wanting to tell us something about his gospel as a whole: maybe he is writing, at one level at least, for people who may have some idea of Jesus but find he is more elusive than they had imagined. Finding him, of course, will normally involve a surprise. Jesus doesn’t do or say what Mary and Joseph, or the two on the road, were expecting.
