Dame Sarah Mullally was installed as the 106th Archbishop of Canterbury at Canterbury Cathedral on March 25, becoming the first woman to lead the Church of England in its 1,400-year history. She succeeds Justin Welby, who resigned in November 2024 after a report found the church had covered up a 1970s serial abuse case on his watch. Mullally, 63, was a cancer nurse who rose to chief nursing officer for England before being ordained a priest at 40 and becoming the first female Bishop of London in 2018. She now leads 85 million Anglicans worldwide. But weeks before her installation, conservative Anglican churches meeting in Nigeria launched a parallel structure called the Global Anglican Communion, declaring it the legitimate Anglican family — and her appointment a "missed opportunity."

1. A 1,400-Year Ceiling Just Broke (Progressives, Anglican Women, Supporters)

A cancer nurse who became a priest at 40 now leads 85 million Anglicans. That matters.

Mullally's path to Canterbury looked nothing like her predecessors'. She spent three decades in the NHS, rising to chief nursing officer for England in 1999 — the first archbishop to have ever led a major public agency. She's only the second since the Middle Ages to hold the office without an Oxford or Cambridge degree. Five African women bishops attended her installation.

The Church of England only began ordaining women as priests in 1994. The first female bishop wasn't consecrated until 2015. Eleven years later, a woman runs the whole institution. A network of ordained women helped navigate Mullally to Canterbury. For a church that spent centuries debating whether women could serve at all, the pace of change is extraordinary.

2. She's Leading a Church That's Already Split (GAFCON, Global South Anglicans, Conservative Evangelicals)

They rejected her appointment, launched a rival communion, and elected their own leaders. The split is structural.

GAFCON bishops meeting in Abuja, Nigeria rejected Mullally's appointment outright. They accused her of promoting "unbiblical teaching on marriage and sexual morality" — a reference to her support for blessing same-sex couples. They shelved a plan to elect a rival archbishop but went further: launching the Global Anglican Communion as a parallel structure with its own council and leadership. Global South Anglicans called the appointment a "missed opportunity."

The opposition is about more than one woman's theology. The conservative Anglican world — concentrated in Africa and Asia, where the communion is growing fastest — rejects both women's ordination and same-sex blessings. Mullally represents the convergence of both. The parallel communion isn't a protest. It's an institution. And it claims to represent the majority of practicing Anglicans globally.

3. The Abuse Scandal Isn't Behind Her (Safeguarding Advocates, Abuse Survivors, Secular Critics)

She inherited a church that covered up serial abuse. Her own safeguarding record has been questioned.

Justin Welby didn't retire — he was forced out. A report found the Church of England had covered up a 1970s serial abuse case, and that Welby failed to report the abuses to authorities when he learned of them in 2013. The resignation created the vacancy Mullally now fills. She has pledged to "do all I can to ensure that the Church becomes safer and responds well to victims and survivors."

But her own record has faced scrutiny. The National Secular Society accused Mullally of a safeguarding breach in December 2025, shortly after her appointment was announced. The details are contested, but the timing undercuts the narrative that Mullally represents a clean break from the Welby era. Survivors aren't looking for promises. They're looking for structural change in how the church handles abuse — and whether the new archbishop will be any different from the last.

Where This Lands

Mullally's installation is historic — the first woman to lead the Church of England since its founding. But she inherits a communion splitting in real time over gender and sexuality, an abuse crisis that forced out her predecessor, and questions about her own safeguarding record. Where this lands depends on whether she can hold together a church whose conservative wing has already walked out — or whether the parallel communion becomes the story.
