In the way of a slight editorial I offer the following thoughts on St Patrick's Day.
Much like Halloween, St Patrick's Day has been taken over and redefined, rudely commercialised, made into, something it was not. Today there are very silly outward expressions to celebrate this great man's day, such as dyeing lager beer green, or rivers green, or wearing over-sized green clothing, followed by too much drink and too much food, and all the while not a thought given to Saint Patrick, nor his feast day.
There is also the real St Patrick's Day, An lá fhéile Pádraig, the Patron Saint of Ireland, a historical figure that brought much good to Ireland. A Celt himself, from the Cymro population of the Britain. His day we celebrate and we enjoy a feast on this day because it is a 'feast' day during the season of Lent. The day is one of wholesome celebration of Ireland's Patron Saint by Irish and Northern Irish Christians, family's gather, good food is served, there is ól, ceol, agus craic, but with decorum and observation of the gravity of the day and tomorrow it is back to Lent.
A good way to remember St Patrick is to read his writings. Two genuine writings of Saint Patrick are in existence today. These writings have become public only during the 19th century. One is "The Confession", an autobiography of Saint Patrick near the end of his life. Another is "A letter to Coroticus", containing a fierce complaint against Coroticus who had raided a number of Patrick’s converts. Both of these can be found online with a Google search and are highly recommended as part of a real St Patrick's Day celebration.
