As J. Geils said, love stinks, yeah, yeah. And it’s based on a bunch of lies, including the notion that there was one super-romantic man named Valentine. The Associated Press and Snopes are committed to telling you the truth.
Ancient sources reveal that there were several St. Valentines who died on Feb. 14. Two of them were executed during the reign of Roman Emperor Claudius Gothicus in 269-270 A.D., at a time when persecution of Christians was common.
How do we know this? Because, an order of Belgian monks spent three centuries collecting evidence for the lives of saints from manuscript archives around the known world. …
…[N]one of the Valentines seems to have been a romantic. … Indeed, medieval legends, repeated in modern media, had St. Valentine performing Christian marriage rituals or passing notes between Christian lovers jailed by Gothicus. Still other stories romantically involved him with the blind girl whom he allegedly healed. Yet none of these medieval tales had any basis in third-century history, as the Bollandists pointed out.
… For believers, relics of the martyrs signified the saints’ continuing their invisible presence among communities of pious Christians. In 11th-century Brittany, for instance, one bishop used what was purported to be Valentine’s head to halt fires, prevent epidemics, and cure all sorts of illnesses, including demonic possession.
As far as we know, though, the saint’s bones did nothing special for lovers.
