Characteristics
The Plymouth Brethren are generally dispensational, pre-tribulational, premillennial in their theology and have much in common with other conservative evangelical Christian groups. They believe in the "Eternal Security" of the true Bible-believing Christian with each believer being subject to "grace" and not "law". In Open Brethren meetings each local assembly is independent and autonomous, so the characteristics of each may differ to a greater or lesser degree, which makes it difficult to describe distinctive characteristics. Exclusive Brethren meetings are more affiliated to one another, but characterising their meetings is made difficult because over the years they have split many times into many divisions.
Essentially, therefore, the Brethren have no central hierarchy to dictate a statement of faith, and even local assemblies tend not to give tacit adherence to any of the historic "Creeds" and "Confessions of Faith" such as are found in many Protestant denominations. This is not because they are opposed to the central sentiments and doctrines expressed in such formulations but rather because they hold the Bible as their sole authority in regard to matters of doctrine and practice. Like many non-conformist churches, Brethren observe only the two ordinances of Baptism and Communion.
Their notable differences from other Christian groups lie in a number of doctrinal beliefs that affect the practice of their gatherings and behaviour. These differences can be summarised as follows:
