"If evangelical and fundamentalist ways of thinking differ on both content and practice, evangelical theology differs from classical protestant orthodoxy more on method. Evangelicalism tends to use the principle of ‘’sola scriptura’’ more radically than the Protestant traditions out of which it grew. That is, when it subscribes to the doctrines of the great creeds of the church (yet some evangelicals and their theologians don’t crying “No creed but the Bible!”), they do so not because the creeds teach the doctrines but because they believe the doctrines have biblical support. Evangelical theologians are not always averse to reading the great fathers and mothers of the church (such as Macrina, Catherine of Siena, Teresa of Avila, and now Mother Teresa) or to learn from the historic confessions, but they typically insist that they do so with critical care. They want to reserve the right to use Scripture as a trump card over tradition when they see conflict between the two. Others, such as “post-conservative” Roger Olson, say they want to be open to further light breaking out from the Word that might compel either a reshaping of doctrine or new doctrine entirely. Evangelical theologians say they reject liberalism’s faith in human experience as a final norm for truth and morality. Against the homogenizing tendency of liberal theology, which would postulate an underlying religiosity common to all faiths evangelical theology emphasizes the particularity of Christian revelation and the uniqueness of Christian spirituality. While liberals place a premium on person autonomy and appeal to internal norms (conscience and religious experience), evangelicals have usually stressed human responsibility to God who has given us external norms in Jesus Christ and Scripture."
