The relationship between Barth, liberalism, and fundamentalism goes far beyond the issue of inerrancy, however. From Barth's perspective, liberalism, as understood in the sense of the 19th century with Friedrich Schleiermacher and Hegel as its leading exponents and not necessarily expressed in any particular political ideology, is the divinization of human thinking. This, to him, inevitably leads one or more philosophical concepts to become the false God, thus attempting to block the true voice of the living God. This, in turn, leads to the captivity of theology by human ideology. In Barth's theology, he emphasizes again and again that human concepts of any kind, breadth or narrowness quite beside the point, can never be considered as identical to God's revelation. In this aspect, Scripture is also written human language, which bears witness to the self-revelation of God in Jesus Christ. Scripture cannot be considered as identical to God's self-revelation, which is properly only Jesus Christ. However, in his freedom and love, God truly reveals himself through human language and concepts, with a view toward their necessity in reaching fallen humanity. Thus Barth claims that Christ is truly presented in Scripture and the preaching of the church, echoing a stand expressed in his native Swiss Reformed Church's Helvetic Confession of the 16th century.
