Without using the word, we were acknowledging that in such a context, we are multi-faith. When people of different faiths are found together, in a conference, neighborhood, or nation, they are best described as multi-faith, representing different faiths.
Worldwide trends indicate that multi-faith is both a current reality and our future. The number of people who claim adherence to the major world religions is growing. German philosopher Friedrich Nietzsche and other post-Enlightenment thinkers predicted the death of God and the decline of religious belief over 100 years ago, but their predictions were premature. In fact, secular thinking has long embraced the idea that religion was the socio-political problem, not so much the solution.
If anything, "God is dead" has been replaced with "God is back." Economists John Micklethwait and Adrian Wooldridge, an atheist and a Roman Catholic, wrote a fascinating book in 2008 with that title. In it they noted that while statistics about religious observance are notoriously untrustworthy, most surveys seem to indicate that the global drift toward secularism has halted. Quite a few surveys show religious belief to be on the rise. They reference one source that says that "the proportion of people attached to the world's four largest religions—Christianity, Islam, Buddhism, and Hinduism—rose from 67 percent in 1900 to 73 percent in 2005, and may reach 80 percent by 2025."
