Christianity has many leaders, including the Roman Catholic Pope, the Archbishop of Canterbury and Ecumenical Patriarch Bartholomew of the Eastern Orthodox Church. The faith does not have one supreme leader.
Pope Francis is the leader of the world's estimated 1.2 billion Roman Catholics, according to Evangelical Alliance UK. Justin Welby is the Archbishop of Canterbury and he leads the world's Anglican and Episcopalian congregations. Ecumenical Patriarch Bartholomew is the Archbishop of Constantinople and New Rome. Although he does not exercise authority over the other patriarchs in the Eastern Orthodox communion, he is the first among equals. There are many other leaders of Christianity because the faith split in the 16th century, creating a multitude of denominations, each with its own set of spiritual leaders.
