I have been reading up on third-world theologies recently. One thing that I soon perceived is that third-world theologies are the illegitimate offsprings of liberal theology. The cry for "contextual theologies" often comes from those who find that so-called "traditional" Western theologies are meaningless to the inhabitants of the Third World, and thus the desire to recontextualize the Christian message for their respective cultures.
It is not surprising that people in the Third World find so-called "traditional" Western theologies meaningless for them. Liberalism in all its forms (traditional liberalism, Neo-Orthodoxy etc) are basically Western philosophies that are not grounded in the truth of God's Word. It is not surprising that Third World cultures do not find Hegel, Kierkegaard, Schleiermacher, von Harneck, Ritschl, Barth, Bultmann and others like them relevant.
Sadly, these Third World theologians have jumped from the frying pan into the fire. Having abandoned Liberalism, the "theologies" they advocate have the appearance of relevance while being just as spiritually helpful as the liberalisms they have rejected. A more "holistic" theology that uses concepts meaningful to native folk religions and worldviews can seem more relevant, yet it is just as helpful for the people as Western liberalism has been for Europeans, who have been leaving the faith in droves (as seen in the dying churches of Europe).
Only the Gospel (which has been rejected by mainstream Western theologies since the Enlightenment) is totally relevant for ALL cultures. Only the Gospel is universally relevant. In their rejection of the bankrupt liberalisms, the Third World theologians are only continuing version 2 of the Liberal project. Such theologies are as nourishing as stones to the people, and ultimately cannot save them from the wrath of the Holy God who has revealed His universal message of salvation in the Scriptures.
