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.
Culture of Ireland
The national holiday in the Republic of Ireland is Saint Patrick's Day, that falls on the date 17 March and is marked by parades and festivals in cities and towns across the island of Ireland, and by the Irish diaspora around the world. The festival is in remembrance to Saint Patrick, the patron saint of Ireland. Pious legend credits Patrick with the banishing of the snakes from the island, and the legend also credits Patrick with teaching the Irish about the concept of the Trinity by showing people the shamrock, a 3-leaved clover, using it to highlight the Christian belief of 'three divine persons in the one God'.
