So does what happened according to this news article serve to confirm or refute the truth of Christianity?
Of course the answer is that it confirms the truth of Christianity just as any other fact does, but we do not view facts as evidence from outside of a view of the world wherein they make sense. Unbelievers will undoubtedly attempt to account for the event without having to say that it is obvious Christianity is the Truth just as they do with all other evidence. Still, this is particularly embarrassing evidence for the unbeliever to have to deal with. I doubt that I would be very offended by a follower of the great Invisible Pink Unicorn shouting from a soapbox concerning my sin of not liking cotton candy.
