Worldwide, the Pentecostal movement has proven to be “from above.” It is taken for granted that Pentecostal organizations around the world are integrated into their respective Evangelical Alliances and are an accepted part of evangelical Christianity.

According to research, more than 85% of all missionary and evangelistic projects and activities worldwide today can be traced in some way back to the Pentecostal revival that began 100 years ago in Los Angeles. Where would Christianity be today if that revival had not taken place?

The most dynamic movements and breakthroughs in evangelical Christianity today come from the Pentecostal or charismatic tradition, as do the largest and fastest-growing congregations. If this growth continues, within a few years one in every 10 people in the world will be a Pentecostal or charismatic Christian. Currently, there are already well over 600 million (9% of the world’s population).

On June 18, 1996, a “Declaration of Trust” was signed between the German Evangelical Alliance and the Federation of Free Pentecostal Churches. This “Kassel Declaration”—which, interestingly, was drafted in Kassel—welcomes Pentecostal-charismatic groups into the local Alliances.

In early 2009, nearly 100 years after the Berlin Declaration, the Gnadauer Association and the Mühlheim Association issued a joint statement. Both associations view themselves, by virtue of the Berlin Declaration and the Mühlheim Declaration, “in a special way” as “successors to the individuals who were involved and held responsibility at that time.”
