Britain's Archbishop of Canterbury Rowan Williams leads the Easter Day Eucharist service at Canterbury Cathedral in in Canterbury in south east England April 4, 2010. The Roman Catholic Church in Ireland has lost all credibility over its response to a child sex abuse scandal, the Anglican Communion's spiritual leader told Britain's BBC radio in an interview broadcast on April 3, 2010. The unusually frank criticism of the Catholic Church in Ireland by Archbishop of Canterbury Rowan Williams followed an apology by Pope Benedict over child abuse by priests in Ireland that disappointed victims. The Archbishop of Dublin Diarmuid Martin said Williams later telephoned him to convey his "deep sorrow and regret" for difficulties caused by the remarks.
