 As described by Wilson and Lippy, in general aside from the progress, or otherwise, of local and national unity efforts, Christadelphians in North America continue to regard members of other fellowships as "brethren" and inside the larger denominational circle.Locating the Unamended Christadelphians within larger Christendom is not an easy endeavor.According to the "Encyclopedia of American Religions" the Unamended Christadelphians are members of the Baptist tradition of Christian denominations, based on their historical split with the Campbelites (Church of Christ / Disciples of Christ).
