Essentially, anything that poses as the Gospel or its equivelent is simply unbelief. The Gospel stands completely on its own and needs nothing but the cross/resurrection of Jesus Christ to substantiate it. Only the Gospel is gospel…and everything else…is something other.
“Any cultural or political agenda embellished with such authority is a manifestation of “works righteousness” and ipso facto an act of apostasy. This theological proposition, over and beyond all prudential moral judgments, “hits” in all directions of the ideological spectrum; it “hits” the center as much as the left or the right. “Different gospels” lurk all across the spectrum. No value or institutional system, past or present or future, is to be identified with the gospel. The mission of the church is not to legitimate any status quo or any putative alteration of the status quo. The “okay world” of bourgeois America stands under judgment, in the light of the gospel, as does every other human society. Democracy or capitalism or the particular family arrangements of middle-class culture are not to be identified with the Christian life, and neither is any alternative political, economic, or cultural system. The vocation of the church is to proclaim the gospel, not to defend the American way of life, not to “build socialism,” not even to “build a just society” – because, quite apart from the fact that we don’t really know what this is, all our notions of justice are fallible and finally marred by sin. The “works righteousness” in all these “different gospels” lies precisely in the insinuation that, if only we do this or refrain from doing that, we will be saved, “justified.” But, as Paul tells us, “by works of the law shall no one be justified.” [Berger, “Different Gospels: The Social Sources of Apostasy,” Erasmus Lecture, January 22, 1987]”
