I didn't really have much to say today so I decided to do some reading on St. Patrick's Day (since it is today). I know I've heard and read things about St. Patrick before, but, you know, I've mostly forgotten it. So I read a few different articles and, actually, good ol' wikipedia has some decent content on the topic. Below are some snippets from the wiki link that were of particular interest to me regarding Patrick and Christianity (underlined parts by me).
Saint Patrick's Day, or the Feast of Saint Patrick, is a cultural and religious celebration held on 17 March, the traditional death date of Saint Patrick (c. AD 385–461), the foremost patron saint of Ireland.**************************
Saint Patrick's Day was made an official Christian feast day in the early 17th century and is observed by the Catholic Church, the Anglican Communion (especially the Church of Ireland), the Eastern Orthodox Church, and the Lutheran Church. The day commemorates Saint Patrick and the arrival of Christianity in Ireland, and celebrates the heritage and culture of the Irish in general. Celebrations generally involve public parades and festivals, céilithe, and the wearing of green attire or shamrocks. Christians also attend church services and the Lenten restrictions on eating and drinking alcohol are lifted for the day, which has encouraged and propagated the holiday's tradition of alcohol consumption.
Saint Patrick's Day is celebrated in more countries than any other national festival.
Patrick was a 5th-century Romano-British Christian missionary and bishop in Ireland. Much of what is known about Saint Patrick comes from the Declaration, which was allegedly written by Patrick himself. It is believed that he was born in Roman Britain in the fourth century, into a wealthy Romano-British family. His father was a deacon and his grandfather was a priest in the Christian church. According to the Declaration, at the age of sixteen, he was kidnapped by Irish raiders and taken as a slave to Gaelic Ireland. It says that he spent six years there working as a shepherd and that during this time he "found God". The Declaration says that God told Patrick to flee to the coast, where a ship would be waiting to take him home. After making his way home, Patrick went on to become a priest.
According to tradition, Patrick returned to Ireland to convert the pagan Irish to Christianity. The Declaration says that he spent many years evangelising in the northern half of Ireland and converted "thousands". Patrick's efforts against the druids were eventually turned into an allegory in which he drove "snakes" out of Ireland (Ireland never had any snakes).
Christians also attend church services and the Lenten restrictions on eating and drinking alcohol are lifted for the day. Perhaps because of this, drinking alcohol – particularly Irish whiskey, beer or cider – has become an integral part of the celebrations. The St Patrick's Day custom of 'drowning the shamrock' or 'wetting the shamrock' was historically popular, especially in Ireland. At the end of the celebrations, shamrock is put into the bottom of a cup, which is then filled with whiskey, beer or cider. It is then drank as a toast; to St Patrick, to Ireland, or to those present. The shamrock would either be swallowed with the drink, or be taken out and tossed over the shoulder for good luck.
On St Patrick's Day it is customary to wear shamrocks and/or green clothing or accessories (the "wearing of the green"). St Patrick is said to have used the shamrock, a three-leaved plant, to explain the Holy Trinity to the pagan Irish. This story first appears in writing in 1726, though it may be older. In pagan Ireland, three was a significant number and the Irish had many triple deities, a fact that may have aided St Patrick in his evangelisation efforts. Patricia Monaghan says there is no evidence that the shamrock was sacred to the pagan Irish. However, Jack Santino speculates that it may have represented the regenerative powers of nature, and was recast in a Christian context—icons of St Patrick often depict the saint "with a cross in one hand and a sprig of shamrocks in the other". Roger Homan writes, "We can perhaps see St Patrick drawing upon the visual concept of the triskele when he uses the shamrock to explain the Trinity".****************************
