So, really: St Paddy's day isn't about drinking and lucky shamrocks and wearing green, it's about the Christians driving pagans out and, which some people may think is kinda funny, but getting rid of the 'snakes' in Ireland, snakes being the symbol of early Irish pagans.
"Saint Patrick (Latin: Patricius[2], Irish: Naomh Pádraig) was a Roman Britain-born Christian missionary and is the patron saint of Ireland along with Brigid of Kildare and Columba. When he was about sixteen he was captured by Irish raiders and taken as a slave to Ireland, where he lived for six years before escaping and returning to his family. He entered the church, as his father and grandfather had before him, becoming a deacon and a bishop. He later returned to Ireland as a missionary in the north and west of the island, but little is known about the places where he worked and no link can be made between Patrick and any church. By the eighth century he had become the patron saint of Ireland. The Irish monastery system evolved after the time of Patrick and the Irish church did not develop the diocesan model that Patrick and the other early missionaries had tried to establish."
From Wikipedia
"One of the reasons he's so famous is because he drove the snakes out of Ireland, and was even credited with a miracle for this. What many people don't realize is that the serpent was actually a metaphor for the early Pagan faiths of Ireland."
