“Pneumatology: Exploring the Work of the Spirit” was the title of a November 2004 symposium sponsored by the John Templeton Foundation. The conference participants offered a range of perspectives on issues related to Pentecostal spirituality

The Azusa Street Centennial was the major Pentecostal anniversary observance and was held April 25-29, 2006, in Los Angeles. It featured a raft of famous Pentecostals, led by T.D. Jakes, Paula White, Benny Hinn and Kenneth Copeland.

In October 2006, the Pew Forum on Religion & Public Life released a 10-country survey on Pentecostals and charismatics (whom it together calls “renewalists”), covering issues of practice and belief. It found that one in four Christians are part of these movements. Read the executive summary, which links to the 233-page PDF report.

A 2002 poll indicated 86 percent of Pentecostals said religion was “very” important in their lives, and 88 percent said they believed religion could solve all or most of the major problems facing the country.
