No, the Brotherhood is not a mystic. The Brothers Movement began in the late1820s, and it is a Christian reform movement in Ireland and Britain, with Damien, Muller and Anthony groves as its main representatives. They put special emphasis on obeying the words of the Bible, giving up formal organizations, and having no general assembly, branches, priests or laymen. All believers call each other "brothers" and "sisters". Outsiders call them Plymouth Brethren according to their characteristics.
