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.
Saint Patrick
Saint Patrick (; ; ) was a fifth-century Romano-British Christian missionary and bishop in Ireland. Known as the "Apostle of Ireland", he is the primary patron saint of Ireland, the other patron saints being Brigit of Kildare and Columba. He is venerated in the Roman Catholic Church, the Anglican Communion, the Lutheran Churches, the Old Catholic Church, and in the Eastern Orthodox Church as equal-to-the-apostles and "Enlightener of Ireland".
