Pope Leo and Archbishop of Canterbury Sarah Mullally met at the Vatican on Monday for their first official audience, exchanging gifts and praying together in a symbolic gesture of unity between the Catholic Church and the Church of England. The meeting marked a historic moment as Mullally became the first woman to lead the world’s Anglicans, while Leo, the first U.S. pope, urged both churches not to let modern divisions stand in the way of working together to spread the Christian faith.
