Plymouth Brethren

The Plymouth Brethren or Assemblies of Brethren are a low church and Nonconformist Christian movement, the history of which can be traced back to Dublin, Ireland, in the mid to late 1820s, where it originated from Anglicanism.

The group emphasizes nuda scriptura, the belief that the Bible is the only authority for church doctrine and practice. They also emphasize the priesthood of all believers, rejecting any formal clergy and instead having Elders as leadership and performing services. Brethren also have simple worship services centered on the Lord's Supper.

The movement is split into two main branches: the Open Brethren, who maintain more flexible engagement with wider society, and the Exclusive Brethren, who focus more on the separation from worldly influences.

Plymouth Brethren generally see themselves as a network of like-minded free churches, not as a Christian denomination.
