An Irish American tradition, the day named for St Patrick has spread around the world. Wanting to keep in touch with their roots, Irish of the 18th and 19th centuries wore green and celebrated their heritage within the scope of the Church’s daily mass.
St Patrick wasn’t Irish but an Englishman kidnapped and put into service. He escaped from Ireland but returned to convert the Irish to Catholicism. He used the cover leaf to explain how one god was three. Later the leaf symbol came to represent luck.
Today, people around the world celebrate leprechauns & fariy folk, dance and have an all around good time. Happy St Patrick's Day!
