First female Archbishop of Canterbury still an outlier among world's top religious leaders

For the first time, a woman will serve as the Archbishop of Canterbury , following the 105 men who have held the role since St. Augustine took the position in the year 597.

This means Bishop of London Sarah Mullally has broken through the Church of England’s highest stained-glass ceiling. But for many of the world’s religions, that barrier to women in top leadership remains firmly intact.
