Dame Sarah Mullally presides over a Palm Sunday worship service as Bishop of London at St. Paul's Cathedral in London. Sarah Mullally has been named the 106th archbishop of Canterbury, a historic decision by the Church of England that places a woman as leader of the church and as first among equals among bishops in the 85 million-strong worldwide Anglican Communion. For the first time, the 17-member commission included five representatives from the churches outside the United Kingdom, mostly in the former British Empire, that make up the bulk of the Anglican Communion. Marriage has been extended to gay couples in the United Kingdom as a civil matter, but not in the Church of England. More immediately, Mullally will need to be elected by the College of Canons of Canterbury Cathedral with confirmation of that election by a special ecclesiastical court, when she will legally become the new archbishop of Canterbury.
