“An Arian Bishop of theirs coming to the city of Spoleto, and not having any place where to exercise his religion, demanded a church of the Bishop of that town: which when he constantly denied him, the Arian prelate told him, that the next day he would by force take possession of St. Paul’s church, which was hard by his lodging. The keeper of the church, understanding this news, in all haste ran thither, shut the doors, and with locks and bolts made them as fast as he could: and when it was night he put out all the lamps, and hid himself within. The next morning, very early, the Arian Bishop came thither with many in his company: meaning by force to break open the doors. But suddenly by miracle the locks were cast far off, and the doors of themselves, making a great noise, flew open: and all the lamps, before put out, were lightened again by fire descending from heaven: and the Arian Bishop that came to enter the church by violence, was suddenly struck blind, so that other men were fain to lead him back again to his own lodging. Which strange accident when the Lombards there about understood, they durst not any more presume to violate Catholic places: and so it fell out wonderfully, by God’s providence, that for as much as the lamps in St. Paul’s church were by reason of him put out: that at one and the self same time, both he lost the light of his eyes, and the church received her former light again.” – Gregory the Great, Dialogues (Book III, Chapter 29).
