Traditional religion is the mainstream, but it is not the only form in which religion appears today. There is also liberal religion. One can hardly speak of liberal Islam, as liberalism is essentially a nonexistent force in the Muslim world. But there are liberal Jews, whose Jewishness seems largely a matter of historical memory and cultural habits. Here in the West, there are lots of liberal Christians. Some of them have assumed a kind of reverse mission: instead of being the church’s missionaries to the world, they have become the world’s missionaries to the church. They devote their moral energies to trying to make the church more democratic, to assure equal rights for women, to legitimize homosexual marriage, and so on. A small but influential segment of liberal Christianity rejects all the central doctrines of Christianity. H. Richard Niebuhr famously summed up their credo: “A God without wrath brought men without sin into a kingdom without judgment through the ministrations of a Christ without a cross.”3

I have met liberal Christians who are good and sincere people. But their version of Christianity is retreating, in two senses. Liberal Christians are distinguished by how much intellectual and moral ground they concede to the adversaries of Christianity. “Granted, no rational person today can believe in miracles, but …” “True, the Old Testament God seems a mighty vengeful fellow, but….” “Admittedly religion is responsible for most of the conflict and oppression in history, but….”

This yes-but Christianity in full intellectual withdrawal, and it is also becoming less relevant. The liberal churches are losing members in droves. Once these churches welcomed one in six Americans; now they see one in thirty. In 1960 the Presbyterianchurch had 4.2 million members; now it has 2.4 million. The Episcopal church had 3.4 million; now it has 2.3 million. The United Church of Christ had 2.2 million; now it has 1.3 million!’ Traditional Christians who remain within liberal churches become increasingly alienated. Some have become so disgusted that they have put themselves under the authority of more traditional clerics based in countries like Nigeria, Ghana, and the Ivory Coast.

Unfortunately the central themes of some of the liberal churches have become indistinguishable from those of the American Civil Liberties Union, the National Organization for Women, and the homosexual rights movement. Why listen to Episcopal bishop John Shelby Spong drone on when you can get the same message and much more interesting visuals at San Francisco’s gay pride parade? The traditional churches, not the liberal churches, are growing in America. In 1960, for example, the churches affiliated with the Southern Baptist Convention had 8.7 million members. Now they have 16.4 million.5

The growth of traditional religion and the decline of liberal religion pose a serious problem for a conventional way of understanding religious trends. This is the way of secularization: the idea that as an inevitable result of science, reason, progress, and modernization, the West will continue to grow more secular, followed by the rest of the world. The more confident exponents of secularization believe, as Peter Berger puts it, that “eventually Iranian mullahs, Pentecostal preachers, and Tibetan lamas will all think and act like professors of literature at American universities.”6
