who established the first christian church in ireland
History of Christianity in Ireland The introduction of Christianity to Ireland dates to sometime before the 5th century, presumably in interactions with Roman Britain. Christian worship had reached pagan Ireland around 400 AD. It is often misstated that St. Patrick brought the faith to Ireland, but it was already present on the island before Patrick arrived. Monasteries were built for monks who wanted permanent communion with God. The lengths they went to for tranquility are evident from the monastery of Skellig Michael. Via Aidan, Christianity spread among the Picts and Northumbrians.
