 In the words of Albert Mohler, president of the Southern Baptist Theological Seminary, confessional evangelicalism refers to "that movement of Christian believers who seek a constant convictional continuity with the theological formulas of the Protestant Reformation".While approving of the evangelical distinctions proposed by Bebbington, confessional evangelicals believe that authentic evangelicalism requires more concrete definition in order to protect the movement from theological liberalism and from heresy.According to confessional evangelicals, subscription to the ecumenical creeds and to the Reformation-era confessions of faith (such as the confessions of the Reformed churches) provides such protection.
