Some Eastern Orthodox propose the theory that the Church in Ireland had experienced a long period of impaired communication and communion with the Holy See prior to the Great Schism of 1054.Bede noted in his Ecclesiastical History of the English People that the Synod of Whitby in 663-664 put Celtic Christians in opposition to continental Catholics and their ritual practices.Due largely to immigration from Eastern Europe, especially Romania, the number of Orthodox Christians in the Republic of Ireland has doubled in recent years.He served a growing congregation of Russian White émigrés, Greek immigrants, and Irish-born converts from a Dublin house chapel until his death in May 1977.The services are mainly conducted in Church Slavonic, but a considerable amount of English is also used along with smatterings of Greek, Georgian, Romanian, Serbian and the Irish language.During the meeting, the Ecumenical Patriarch and the newly appointed Synodal Hierarchs, led by Metropolitan Makarios of Anea, exchanged customary salutations and responses.Starting in January 2001, Sunday worship has taken place in Belvedere College Chapel in the centre of Dublin, courtesy of the Jesuit Fathers.From 2010, the Romanian Orthodox parish of Ballsbridge had been operating from two alternative locations in Blanchardstown: three recently appointed priests hold the liturgy there every Sunday.On 9 April 2006, a fourth priest in Ireland was ordained with responsibility for two new parishes in Cork and Galway (where services are conducted in the Anglican St. Nicholas' Collegiate Church).In 2010 Fr Ioan Irineu Craciun relocated to the Romanian Community after 29 years ministering to Greek Orthodox in Arbour Hill.
