Evangelicalism
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. Confessional evangelicals are represented by conservative Presbyterian churches (emphasizing the Westminster Confession), certain Baptist churches that emphasize historic Baptist confessions such as the Second London Confession, evangelical Anglicans who emphasize the Thirty-Nine Articles (such as in the Anglican Diocese of Sydney, Australia), and some confessional Lutherans with pietistic convictions.
Evangelism
Throughout most of its history, Christianity has been spread evangelistically, though the extent of evangelism has varied significantly between Christian communities, and denominations. Evangelism, apologetics and apostolic ministry often go hand in hand. An ἀπόστολος ("apostolos") is literally "one who is ordered forth" and refers to the missionary calling of being ordered forth into the world by the initiation of God. An example of an interplay between Evangelism and Apologetics can be seen in the US when upon door to door Evangelism the prospect is an unbeliever and challenges the Evangelist wherein the Evangelist then follows into the role of the Apologist in defense of their faith with the hope that Evangelism may be restarted. Since missionaries often travel to areas or people groups where Jesus is not yet known, they frequently take on an evangelistic role. But the apostolic or missionary calling is not necessarily the same (and it is a misnomer and misinterpretation to equate them), as there are many who serve in missionary, church planting, and ministry development roles who have an apostolic calling or serve in an apostolic role but whose primary duty is not evangelism.
