The Plymouth Brethren are a conservative, low church, nonconformist, Evangelical Christian movement whose history can be traced to Dublin, Ireland in the late 1820s, originating from Anglicanism. Among other beliefs, the group emphasizes sola scriptura, the belief that the Bible is the supreme authority for church doctrine and practice over and above "the [mere] tradition of men" (Mark 7:8). Brethren generally see themselves, not as a denomination, but as a network (or even as a collection of overlapping networks) of like-minded independent churches. (The Brethren would generally prefer that their gatherings be referred to as "assemblies," rather than "churches" but, in the interests of simplicity, this article uses both terms interchangeably.)
