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.
Religion in Iceland
Starting in the 1530s, Iceland, originally Catholic and under the Danish crown, formally switched to Lutheranism with the Icelandic Reformation, which culminated in 1550. The Lutheran Church of Iceland has remained since then the country's state church. Freedom of religion has been granted to the Icelanders since 1874. The Church of Iceland is supported by the government, but all registered religions receive support from a church tax ("sóknargjald") paid by taxpayers over the age of sixteen.
