St Patrick

Saint Patrick (Latin: Patricius, Irish: Naomh Pádraig), said to have been born Maewyn Succat (Latin: Magonus Succetus), 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 from his native Wales as a slave to Ireland, where he lived for six years before escaping and returning to his family. After entering the church, 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.
The available body of evidence does not allow the dates of Patrick's life to be fixed with certainty, but it appears that he was active as a missionary in Ireland during the second half of the fifth century. Two letters from him survive, along with later hagiographies from the seventh century onwards. Many of these works cannot be taken as authentic traditions. Uncritical acceptance of the Annals of Ulster (see below) would imply that he lived from 340 to 460, and ministered in what is modern day northern Ireland from 428 onwards.

Most modern studies of Saint Patrick follow a variant of T. F. O'Rahilly's "Two Patricks" theory. That is to say, many of the traditions later attached to Saint Patrick originally concerned Palladius, a deacon from Gaul who came to Ireland, perhaps sent by Pope Celestine I (died 431). Palladius was not the only early cleric in Ireland at this time. Saints Auxilius, Secundinus and Iserninus are associated with early churches in Munster and Leinster. By this reading, Palladius was active in Ireland until the 460s.

Prosper of Aquitaine's contemporary chronicle states:
Palladius was ordained by Pope Celestine and sent to the Irish believers in Christ as their first bishop. Prosper associates this with the visits of Germanus of Auxerre to Britain to suppress the Pelagian heresy and it has been suggested that Palladius and his colleagues were sent to Ireland to ensure that exiled Pelagians did not establish themselves among the Irish Christians. The appointment of Palladius and his fellow-bishops was not obviously a mission to convert the Irish, but more probably intended to minister to existing Christian communities in Ireland. The sites of churches associated with Palladius and his colleagues are close to royal centres of the period: Secundus is remembered by Dunshaughlin, County Meath, close to the Hill of Tara which is associated with the High King of Ireland; Kilashee, County Kildare, close to Naas with links with the Kings of Leinster, is probably named for Auxilius. This activity was limited to the southern half of Ireland, and there is no evidence for them in Ulster or Connacht. Although the evidence for contacts with Gaul is clear, the borrowings from Latin into the Old Irish language show that links with former Roman Britain were many. Saint Iserninus, who appears to be of the generation of Palladius, is thought to have been a Briton, and is associated with the lands of the Uí Cheinnselaig in Leinster. The Palladian mission should not be contrasted with later "British" missions, but forms a part of them. Saint Patrick went under the gaelic second name of Daorbae (meaning - He was enslaved) so, he was known as Patricius Daorbae, during his Irish ministry.

March 17, popularly known as St. Patrick's Day, is believed to be his death date and is the date celebrated as his feast day. The day became a feast day in the universal church due to the influence of the Waterford-born Franciscan scholar Luke Wadding, as a member of the commission for the reform of the Breviary in the early part of the 17th century.
For most of Christianity's first thousand years, canonisations were done on the diocesan or regional level. Relatively soon after the death of people considered to be very holy people, the local Church affirmed that they could be liturgically celebrated as saints. As a result, St. Patrick has never been formally canonised by a Pope; nevertheless, various Christian churches declare that he is a Saint in Heaven (he is in the List of Saints). He is still widely venerated in Ireland and elsewhere today.
St. Patrick is also venerated in the Orthodox Church, especially among English-speaking Orthodox Christians living in the United Kingdom and the Republic of Ireland and in North America. There are Orthodox icons dedicated to him.
On March 17, 1776, the day that British forces under General Sir William Howe evacuated Boston during the American Revolutionary War, the password of the day at General George Washington's Continental Army encampment was "Saint Patrick". The date is observed as Evacuation Day, an official holiday in Suffolk County, Massachusetts, USA. Massachusetts has the most Irish ancestry of the United States in terms of percentage of total population.
