Religion in the Republic of Ireland
Christianity is the largest religion in the Republic of Ireland based on baptisms. Irish Christianity is dominated by the Catholic Church, and Christianity as a whole accounts for 82.3% of the Irish population. Most churches are organized on an all-Ireland basis which includes both Northern Ireland and the Republic of Ireland.
Irish travellers have traditionally adopted a very particular attitude to the Catholic Church, with a focus on figures such as "healing priests". More generally a tradition of visions continues, often outside of Church sanction.
Catholic Church in Ireland
A confusing but defining period arose during the English Reformation in the 16th century, with monarchs alternately for or against Papal supremacy. When on the Death of Queen Mary in 1558, the church in England and Ireland broke away completely from the Papacy, all but two of the bishops of the Church in Ireland followed the decision. Very few of the local clergy led their congregations to follow. The new body became the established State Church, which was grandfathered in the possession of most Church property. This allowed the Church of Ireland to retain a great repository of religious architecture and other religious items, some of which were later destroyed in subsequent wars. A substantial majority of the population remained Catholic, despite the political and economic advantages of membership in the state church. Despite its numerical minority, however, the Church of Ireland remained the official state church for almost three hundred years until it was disestablished on 1 January 1871 by the Irish Church Act 1869 that was passed by Gladstone's Liberal government.
