What is the future of religion? People frequently ask me this question, and I always want to respond like Dr. McCoy in Star Trek: "I'm a historian, not a fortune teller." 

As a historian, I am convinced that there is little more foolhardy than trying to anticipate the future course of religion. Who, after all, would have predicted that the ancient Hebrews could escape slavery in Egypt? That a Jewish carpenter's son would become one of the greatest religious figures in human history? That an Arab orphan would receive a revelation of Allah's true word? Indeed, libraries are full of books confidently predicting the future of religion, from the writings of the Apostle Paul who thought that Jesus would return in his generation to the much-ballyhooed "death of God" in the mid-1960s.

Although certain aspects of religion lend themselves to sociological, cultural, philosophical, psychological, and economic analyses, religion is ultimately about faith -- the human response to the divine is one of the most mysterious of human activities. Religious history is composed of unexpected events, unanticipated motivations, and unlikely characters, making it about as easy to predict as falling in love. Indeed, professional futurologists do not forecast what is coming; instead, they develop maps of potential futures that people might create. As the writer of Ecclesiastes reminds, "Since no man knows the future, who can tell him what is to come?"

Despite the obvious pitfalls of this endeavor, few topics are as lively right now in religious circles as the future. Everyone from denominational leaders to political leaders wish to "see" the religious horizon. There seem to be two camps emerging around the question; one predicts a bull market of faith, the other is claiming a religious collapse. The first group points to the exponential rise of religion in the global south and the growth of fundamentalism of all sorts as evidence of increasing spiritual vitality; the second cites the development of new forms of atheism, agnosticism, and post-theism as well as growing numbers of people who consider themselves unaffiliated to support their contention that religion is eroding (or should be) and is being displaced by either unbelief or vague spirituality. Indeed, the competition between these interpretations is intense, leading to much confusion in religious institutions and denominations as well as in popular culture, the media, and politics as to the current state and future prospects of faith.

Some commentators combine the two views. Religion is growing outside the West while it is declining in West. Although I have never heard this said, I think that this interpretation is an updated version of an old thesis, one proposed in 1972 by Dean M. Kelley's book Why Conservative Churches Are Growing, in which (among other things) the author argues that "strict" or "demanding" religions succeed where more liberal, open, and tolerant faiths fail. However, as even conservative denominations are struggling with significant numerical declines, there is now evidence in United States that contradicts Kelley's oft-repeated thesis.
