David's book Moral Minority: The Evangelical Lefts in an Age of Conservatism is reviewed in this weekend's New York Times Sunday Book Review. Here is a taste of Molly Worthen's review:
So why did the evangelical left seem to dissolve into irrelevance? Swartz argues that evangelicals’ mass enlistment in the conservative Republicanism of the “culture wars” was not the inevitable consequence of doctrine or history: Jesus did not leave behind a clear party platform. But while members of the Christian right set aside doctrinal differences to rally around a shared cultural agenda, the left fell victim to internal identity politics and theological disputes. Black and female evangelicals argued that the left’s leadership was too white and too male. Anabaptists who emphasized nonviolence clashed with Reformed evangelicals who had ambitious plans to transform American culture. Meanwhile, secular liberals, eager to make abortion rights a nonnegotiable plank of the Democratic platform, drove anti-abortion Christians into the arms of savvy Republicans.
Progressive evangelicals tried to halt this migration: “The energy of the pro-life movement must be removed from the ideological agenda of the New Right,” Wallis warned in 1980. As conservatives transformed the fight against abortion from a “Catholic issue” into the defining battle of the culture wars, Wallis and others countered with another idea borrowed from Catholics, the “consistent life ethic” opposing poverty, war and the death penalty as well as abortion. Yet left-wing evangelicals’ measured arguments were no match for cries that abortion is murder and family values are under siege. It seems they were not so mainstream after all: efforts at fund-raising fell flat, and by the mid-’80s half of the subscriptions to Wallis’s magazine, Sojourners, went to Catholics.
