Pentecostalism

Lore & Background

Holiness Pentecostalism emerged in the early 20th century among adherents of the Wesleyan-Holiness movement, energized by Christian revivalism and expectation of the Second Coming of Christ. Along with William J. Seymour, a Wesleyan-Holiness preacher, he taught that this was the third work of grace—though this terminology is more characteristic of Holiness Pentecostalism, and Seymour in particular did not always emphasize three works of grace in the same way.

Reader's Guide

Since the 1960s, Pentecostalism has increasingly gained acceptance from other Christian traditions, and its beliefs concerning the baptism of the Holy Spirit and spiritual gifts have been embraced by non-Pentecostal Christians in Protestant and Catholic churches through the Charismatic movement. The movement is believed to be the fastest-growing religious movement in the world, and its early history included interracial worship that defied social and cultural norms of racial segregation, though North American Pentecostalism would later divide into white and African-American branches.

Did You Know?

• The term Pentecostal is derived from Pentecost, an event described in Acts 2:1–4.
• Pentecostalism is divided into Holiness Pentecostals, who affirm three definite works of grace, and Finished Work Pentecostals, which include trinitarian and non-trinitarian branches.

Theological DNA & Wesleyan Roots

Pentecostalism's theological architecture was assembled from several streams of late-nineteenth-century evangelical revivalism in the United States and Britain. Its deepest roots lie in the Wesleyan-Holiness and Higher Life movements, where leaders such as Dwight L. Moody and R. A. Torrey began preaching that every believer could receive a distinct empowering experience from the Holy Spirit. The Keswick and Higher Life circles already held that all spiritual gifts continued into the modern church, a conviction that proved essential groundwork. Albert Benjamin Simpson's Christian and Missionary Alliance, founded in 1887, shaped early Pentecostal structures—particularly what would become the Assemblies of God—while John Alexander Dowie's Christian Catholic Apostolic Church (1896) and Edward Irving's Catholic Apostolic Church (c. 1831) contributed further charismatic and healing emphases. When isolated groups across the country began reporting tongues-speaking and divine healing, the Holiness Pentecostal movement supplied the missing theological framework, adapting a modified form of Wesleyan soteriology to explain what these Christians were experiencing. The result was a distinctive identity: biblical inerrancy, the necessity of being born again, and a two-track baptism—water and Spirit—that together unlock what adherents call a Spirit-filled, empowered life.

The Topeka Spark & Azusa Street

The movement's catalytic moment arrived in a small spiritual school near Topeka, Kansas. Charles Fox Parham, a Methodist-raised holiness evangelist passionate about divine healing, opened Bethel Bible School in 1900 and began teaching that speaking in tongues was the scriptural proof that a believer had received the baptism with the Holy Spirit. On the night of January 1, 1901, after a watch-night service, his students prayed and reported receiving that baptism with tongues as evidence. Parham himself experienced it shortly afterward and wove it into every sermon. He interpreted the phenomenon as genuine xenoglossia, reasoning that missionaries would no longer need years of foreign-language study. He closed the Topeka school and spent four years touring Kansas and Missouri, teaching that Spirit baptism was a third work of grace following conversion and sanctification—sanctification cleansing the believer, Spirit baptism empowering them for service. William J. Seymour, a Wesleyan-Holiness preacher, carried this theology to Los Angeles, where his three-year Azusa Street Revival became the movement's global launchpad. Visitors returned to their home congregations or felt summoned to the mission field, and virtually every Pentecostal denomination today traces its lineage back to that Los Angeles street.

The Great Fracture & Denominational Mosaic

Despite its shared emphasis on Spirit baptism, Pentecostalism has never operated under a single governing body. The movement now encompasses more than seven hundred Christian denominations alongside countless independent churches, all highly decentralized with no central authority, though many maintain affiliation through the Pentecostal World Fellowship. This structural plurality mirrors deep theological fractures that emerged almost immediately. Early disputes centered on the doctrine of entire sanctification, and later on the nature of the Holy Trinity. The result is a three-way division. Holiness Pentecostals, rooted in the Wesleyan tradition, affirm three definite works of grace—conversion, sanctification, and Spirit baptism. Finished Work Pentecostals, who see sanctification and Spirit baptism as a single event, split further into trinitarian and non-trinitarian branches. The non-trinitarian stream gave rise to Oneness Pentecostalism, which holds a distinct Christological position. This mosaic means that two Pentecostals sitting in adjacent pews may worship in the same charismatic style yet disagree on the very structure of the Godhead. The term "Pentecostal" itself, drawn from the Acts 2 account of the Holy Spirit descending on the Apostles in Jerusalem during the Feast of Weeks, unites the movement more by narrative memory than by institutional cohesion.

From Niche to Global Phenomenon

What began as a small cluster of holiness believers in Kansas and Los Angeles has become, by most estimates, the fastest-growing religious movement on earth. Classical Pentecostalism alone now counts over 279 million adherents worldwide, with particularly vigorous expansion across the Global South and Third World nations. The growth trajectory accelerated dramatically after the 1960s, when Pentecostal convictions about the baptism of the Holy Spirit and the ongoing operation of spiritual gifts began crossing traditional denominational boundaries. Protestant and Catholic Christians outside the Pentecostal fold adopted these beliefs through the broader Charismatic movement. When classical Pentecostals and Charismatics are tallied together, the combined figure exceeds 644 million people. Early Pentecostals themselves understood their experience as a latter-day restoration of the apostolic power described in Acts, and historians such as Cecil M. Robeck Jr. and Edith L. Blumhofer have traced the movement's emergence to the radical evangelical revival currents of the late nineteenth century in both the United States and Great Britain. The trajectory from a single Bible school in Topeka to a global phenomenon spanning seven hundred denominations remains one of the most remarkable stories in modern religious history.
