London, Jan. 29 -- Sarah Mullally was confirmed as archbishop of Canterbury on Wednesday, becoming the first woman to lead the Church of England. The worldwide Anglican Communion, which includes the Episcopal Church in the US, has no formal head, but the archbishop traditionally has been seen as its spiritual leader. Mullally, 63, a cancer nurse turned cleric, officially took up the responsibilities of her new job as judges presided over a legal ceremony confirming her appointment, which was announced almost four months ago. The so-called Confirmation of Election service marks a major milestone for the Church of England, which ordained its first female priests in 1994 and its first female bishop in 2015. The church traces its roots to the 16th century, when the English church broke away from the Roman Catholic Church during the reign of King Henry VIII. George Gross, an expert on theology and the monarchy at King's College London, highlighted the church's continuing divergence from the Catholic Church, which forbids women from being ordained as priests, much less from serving as the religion's global spiritual leader. "It is a big contrast," Gross said. "And in terms of the position of women in society, this is a big statement." But Mullally's appointment may deepen rifts within the Anglican Communion, whose 100 million members in 165 countries are deeply divided over issues such as the role of women and the treatment of LGBTQ people. She will also have to confront concerns that the Church of England hasn't done enough to stamp out the sexual abuse scandals that have dogged it for over a decade....
