Christian Denominations
Three streams of the modern church — where each began, the turning points that shaped it, and how it's practiced today.
Pentecostalism
Pentecostalism is a dynamic Protestant Christian movement that started in the 1900s.
Timeline of Trinitarian Pentecostalism
1901: The modern movement starts in Topeka, Kansas, under Charles Fox Parham.Who was Charles Fox Parham?
1906: The Azusa Street Revival begins in Los Angeles, led by William J. Seymour, cementing core Pentecostal experiences like speaking in tongues.Who was William J. Seymour?
1913: At a camp meeting in Arroyo Seco, California, minister R.E. McAlister preaches a sermon on baptism in the name of Jesus. His message sparks a new non-Trinitarian ("Jesus Only") teaching — though McAlister himself remains Trinitarian.Who was R.E. McAlister?
1914: The Assemblies of God is founded in Hot Springs, Arkansas, by churches and ministers organizing to maintain traditional Trinitarian doctrine and cooperative missions. Up to this point, all Pentecostals were Trinitarian.
1916: The Assemblies of God formally adopts a strict Trinitarian statement of faith, causing non-Trinitarian ministers to officially separate into what becomes Oneness Pentecostalism
Today: Unlike older traditions that trace their roots to the early church fathers, Pentecostalism is a distinctly modern movement — born in the early 1900s and carried forward by innovators who emphasized a fresh, direct experience of the Holy Spirit rather than historic liturgy or apostolic succession.
