Behind every holiday named after a saint theres a reason why, and what they did to earn sainthood.
It all starts in Italy in the middle of a war, it had been waging for years and less and less young men where volunteering or outright refusing to go to war. Desperate for soldiers the emperor decreed that all unmarried young men where to be drafted into the army, as soon as it was declared young sweethearts would marry as fast as they could. After a while he noticed that the army wasn't gaining men so he then began to ban all marriage, so they couldn't get out of being drafted.
It seemed to work for a while until young sweethearts began to ask priests to marry them but they would turn them away not wanting to be punished for breaking the law during war time. All except one a priest by the name of Valentine. He strongly rejected the law believing that marriage is a sacred blessing from God and can not be banned by any man on earth, he believed that people who are truly in love should be banned from marriage and began to marry any who came to him in secret.
Soon the emperor noticed that there seemed to be a larger number of young married men then there were before, it didn't take him long to figure out that someone was marrying young couple in secret. So he sent out a young spy with a fake fiancé to ask about any priest who would marry him and his sweetheart. Soon the spy found out about the priest Valentine and his works, and reported to the king. The next day the church was surrounded and Valentine arrested for treachery to the king and country during war time.
On the day he was to be executed he had to regrets about what he had done, he knew he had don't the good lords work and that he would rise to heaven unafraid of death. Many people who had heard about him all flocked to see him at the gallows and swept when he was hanged. Soon after the emperor realized what he had done and how he was wrong to stop those who where truly in love to be able to be married. From that day Valentine was recognized as a saint and thus St. Valentines day came to be, to celebrate true love and the love shared between family and friends.
Its a shame that i don't hear many people tell this story but St. Valentines day is truly a day to celebrate with loved ones and remembering why this day is so.
