For the most part, the mission of the Brethren was aimed at nominal or otherwise cultural Christians who made up much of organized Christianity. As one friendly observer noted of Darby in 1835, “He says he feels his office principally lies in urging believers to walk worthy of their high and holy calling.”6 The Brethren, like so many like-minded dissenter groups, were passionate to revive existing Christians as much as to make new converts.
