What are followers of the Society of Friends called?

Quakers (or Friends) are members of a historically Christian group of religious movements formally known as the Religious Society of Friends or Friends Church. Members of the various Quaker movements are all generally united in a belief in the ability of each human being to experientially access "the light within", or "that of God in every person".

Some may profess the priesthood of all believers, a doctrine derived from the First Epistle of Peter. They include those with evangelical, holiness, liberal, and traditional Quaker understandings of Christianity. There are also Nontheist Quakers whose spiritual practice is not reliant on the existence of a Christian God. To differing extents, the different movements that make up the Religious Society of Friends/Friends Church avoid creeds and hierarchical structures. In 2007, there were about 359,000 adult Quakers worldwide. In 2012, there were 377,055 adult Quakers, with 52% in Africa.
