I had no clue or desire to know, until I had a conversation where none of us knew how this great holiday came to be, and then of course, I had to find out.
Saint Valentine’s Day, commonly known as Valentine’s Day or the Feast of Saint Valentine, is observed on February 14 each year. It is celebrated in many countries around the world, although it remains a working day in most of them.
St. Valentine’s Day began as a liturgical celebration of one or more early Christian saints named Valentinus. The most popular martyrology associated with Saint Valentine was that he was imprisoned for performing weddings for soldiers who were forbidden to marry and for ministering to Christians, who were persecuted under the Roman Empire; during his imprisonment, he is said to have healed the daughter of his jailer Asterius. Legend states that before his execution he wrote her a letter “from your Valentine” as a farewell. Today, Saint Valentine’s Day is an official feast day in the Anglican Communion, as well as in the Lutheran Church. The Eastern Orthodox Church also celebrates Saint Valentine’s Day, albeit on July 6and July 30, the former date in honor of the Roman presbyter Saint Valentine, and the latter date in honor of Hieromartyr Valentine, the Bishop of Interamna (modern Terni).
The day was first associated with romantic love in the circle of Geoffrey Chaucer in the High Middle Ages, when the tradition of courtly love flourished. By the 15th century, it had evolved into an occasion in which lovers expressed their love for each other by presenting flowers, offering confectionery, and sending greeting cards (known as “valentines”). Valentine’s Day symbols that are used today include the heart-shaped outline, doves, and the figure of the winged Cupid. Since the 19th century, handwritten valentines have given way to mass-produced greeting cards.
