Canterbury Cathedral, March 25, 2026, the Feast of the Annunciation: Sarah Mullally knocked three times on the West Door, was admitted, and was installed as the 106th Archbishop of Canterbury before some two thousand people — the first woman to hold the office in the more than fourteen centuries since St Augustine's arrival in 597.
The installation is the symbolic half of a transition that began in law on January 28, when Mullally's election was confirmed at St Paul's Cathedral in London. In Canterbury she was seated twice: in the Quire Cathedra as Bishop of Canterbury, and in the ancient chair of St Augustine, which marks the Primate of All England. She preached her first sermon as archbishop and presided over a congregation that stretched the cathedral's capacity, per the Church of England's account of the service.
The guest list described the office without a word of commentary. The Prince and Princess of Wales represented the King; the Prime Minister, Sir Keir Starmer, sat with the Leader of the Opposition, Kemi Badenoch. Vatican representatives and Roman Catholic bishops from across the British Isles attended, alongside leaders of the Orthodox and Oriental Orthodox Churches, primates of the Anglican Communion from every continent, and delegations from the Commonwealth, the United Nations, schools and healthcare bodies — the sectors of British public life the archbishop's office has touched since it was an instrument of the medieval state.
The vestments carried the same argument in miniature. Mullally wore the cope and mitre from her consecration as a bishop, and a specially designed morse fastened with a buckle taken from her belt as an NHS nurse — the career that preceded her ordination. She received a crosier given to Archbishop Geoffrey Fisher in 1961 by senior archbishops of the Anglican Communion, and she wore the ring that Pope Paul VI gave Archbishop Michael Ramsey in Rome on March 24, 1966, almost exactly sixty years before — an heirloom of the Anglican-Roman Catholic dialogue that began in that meeting.
On her appointment in October 2025 she had set her own theme: I intend to be a shepherd who enables everyone's ministry and vocation to flourish, whatever our tradition.
Why it matters: the Annunciation date, chosen for a feast that turns on a woman's answer to a call, framed an institutional first — but the office Mullally now holds is not symbolic. She presides over the Church of England's synods and houses of bishops, appoints to its senior posts, and stands first among the primates of a global communion whose provinces do not all ordain women, some of which will not recognize her ministry. The service in Canterbury closed one question; the ones it opened now move to the church's working calendar.
