Who was Saint Patrick?

Despite his prevalence, mainly the holiday set aside to celebrate the day of his death, St. Patrick’s life remains surrounded in mystery. He was born in Britain in the late 4th century and would later be captured by Irish raiders. It’s believed St Patrick turned to religion and became a devout Christian during his captivity. He would also escape captivity, become a priest and return to Ireland on a mission to convert more people to Christianity. Here are some interesting facts about the patron saint of Ireland:

• He Wasn’t Irish: Some people assume the patron saint of Ireland isn’t Irish, but he isn’t. St Patrick was born in Britain, and his father was a Christian deacon. Surprisingly, Patrick’s family wasn’t particularly religious. It’s believed his father took on the job because of tax incentives.

• He was Captured at 16: At the age of 16, Irish raiders captured Patrick and brought him to Ireland, where he would spend the next six years. St Patrick served as a shepherd outdoors and away from others during his captivity years. It’s believed the solace drove him to his religion, after which he began having visions of converting pagan Irish people to Christianity.

• He Escaped Captivity: After six years in captivity, St Patrick escaped and walked nearly 200 miles to reach Britain. He would then report a second vision where an angel told him to return to Ireland as a missionary. Fifteen years of religious training later, St Patrick was ordained as a priest and sent to Ireland to minister to existing Christians and convert the pagans to Christianity.

History of Saint Patrick’s Day

St Patrick’s Day is held every year on March 17th, the date believed to be the passing day of the patron. Although current celebrations are boisterous, involving huge parades and green beer, St Patrick’s Day is a holy day in Christianity. The modest religious holiday was established in 1631 to honor the patron saint of Ireland.

In its early years, St Patrick’s Day provided a break from the fasting period leading up to Easter (Lent). People took the advantage to celebrate, feast and drink, but the day didn’t become a recognized public holiday until 1904. The modern scene around the March 17th celebrations comes from Irish immigrants in the US.

Boston and New York saw the number of parades increase tremendously between the 1700s and 1900s. As the Irish population grew, so did the parades and celebrations. Festive enthusiasts began wearing green clothes, eating cabbage and corned beef, and attending massive parades.

St Patrick’s Day is today a general holiday for Christians to celebrate with friends and family. It’s a cultural celebration involving Irish beer, whiskey, and grand parades. Many people celebrate the feast to mark the commemoration of Christianity in Ireland and the works of St Patrick.
