St. Valentine (3rd Century AD) was a holy priest and bishop who lived during a time when Christians were not welcomed in the Roman Empire. He helped many who were imprisoned or were hiding from Roman soldiers. In the end, St. Valentine himself was captured and killed for his faith. He died on 14 February, which became known as St. Valentine's Day. This day became a lovers' holiday because it was said that St. Valentine was killed for marrying Christian couples.
