From First Things, confirmation of one of my opinions (hat tip: Paul Halsall):
When we encounter “pagan-seeming” images or practices in medieval Christianity, we should consider the probability that they were simply expressions of popular Christianity before positing the existence of secret pagan cults in medieval Western Europe. Once we accept that most culturally alien practices in popular Christianity were products of imperfectly catechized Christian cultures rather than pockets of pagan resistance, we can begin to ask the interesting questions about why popular Christianity developed in the ways it did. Rejecting the myth of the pagan Middle Ages opens up the vista of medieval popular Christianity in all its inventiveness and eccentricity. After the first couple of centuries of evangelization, there were no superficially Christianized pagans—but there remained some very strange expressions of Christianity.
That’s the conclusion, but I enjoin you to read the whole thing.
