Pentecostalism: A 20th Century Explosion

It began with a whisper but ended in a roar. In the early 1900s, a spiritual movement exploded across America and quickly swept the globe. With spontaneous worship, ecstatic utterances, and bold claims of miracles, Pentecostalism upended the religious landscape and challenged long-established church norms.

What made it so powerful? What made it so controversial?

Was this the long-awaited outpouring of the Holy Spirit—or an emotional wildfire fueled by desperation and excess?

In this article, True Jesus Way will explore the rise of Pentecostalism in the 20th century: its roots, key events, global impact, doctrinal distinctives, and the spiritual questions it continues to raise for the Church today.

📜 The Story of Pentecostalism — From Obscurity to Global Movement

The Seedbed: 19th Century Holiness and Revivalism

Pentecostalism didn’t come from nowhere. Its roots stretch back to the Holiness movement of the 1800s, which itself was birthed in the aftermath of the Second Great Awakening. Influenced by Methodism, Holiness preachers like Phoebe Palmer and Charles Finney emphasized entire sanctification—a second experience after salvation that purified believers and empowered them for holy living.

At the same time, waves of revivalism across North America and Europe were stirring spiritual hunger, while fresh missionary zeal inspired believers to expect a new move of God. Some began reading Acts 2 literally—believing that speaking in tongues, healings, and miracles weren’t just for the early church but should be normative for all Christians.

The Flashpoint: Azusa Street Revival (1906–1909)

The spark that lit the fire came from an unlikely source: a one-eyed Black preacher named William J. Seymour.

After studying under Charles Parham—who taught that speaking in tongues was the initial evidence of Spirit baptism—Seymour moved to Los Angeles in 1906. What began as a small prayer meeting on Bonnie Brae Street soon moved to a humble building on 312 Azusa Street, and revival erupted.

Eyewitnesses described intense scenes: people speaking in tongues, falling under the power of the Spirit, being healed, and crying out in repentance. The atmosphere was interracial, Spirit-led, and unstructured. No celebrity pastors. No denominational credentials. Just prayer, praise, and power.

Visitors came from around the world—and took the fire home with them.

Spreading Like Fire: Pentecostal Missions and Denominations

Within a few decades, Pentecostalism had become a global movement.

Major denominations were founded to organize the growth:

• Assemblies of God (1914) – now the largest Pentecostal denomination globally
• Church of God in Christ (COGIC) – rooted in Black Holiness traditions
• Foursquare Church (1923) – founded by Aimee Semple McPherson, blending healing, media, and evangelism
• Pentecostal Holiness Church – emerged from Methodist and Holiness roots

Missionaries went out boldly, believing tongues were not only spiritual but literal languages that would empower them to preach to foreign nations without learning the local dialect. While this proved inaccurate, it showed how intensely Pentecostals believed God was restoring apostolic power to the modern church.

Renewal and Expansion: The Charismatic Movement

In the 1960s and 70s, Pentecostal-style experiences began entering mainline Protestant and Roman Catholic churches. This wave became known as the Charismatic Movement.

Unlike classical Pentecostals, Charismatics didn’t always leave their denominations. They stayed—and brought with them tongues, healings, and prophecies. Catholic Charismatics emphasized prayer groups and praise gatherings, blending Pentecostal spirituality with sacramental theology.

Meanwhile, the Third Wave of the Spirit (coined by C. Peter Wagner in the 1980s) emphasized healing, prophecy, and deliverance without necessarily emphasizing tongues as the initial evidence.

All these waves shared a belief: The Holy Spirit is active, personal, and powerful today—just as in Acts.

📖 Spiritual and Doctrinal Discernment

What Truths Did Pentecostalism Revive?

1. The Active Ministry of the Holy Spirit
   Pentecostalism reminded the Church that the Holy Spirit is not a doctrine but a living Person. His gifts, power, and presence were not just for the first century.
2. Expectancy and Bold Faith
   Pentecostals prayed like they believed God would answer—because they did. Faith wasn’t theory; it was action. This birthed healing ministries, bold missionary ventures, and passionate worship.
3. Unity Across Boundaries
   Early Azusa Street worshippers defied race, class, and gender norms. While later divisions occurred, the revival initially modeled a powerful expression of unity in Christ through the Spirit.
4. Prayer-Centered Spirituality
   Pentecostalism emphasized tarrying, fervent intercession, and Spirit-led worship. These were not “add-ons” to faith—they were core.

What Errors and Excesses Emerged?

1. Overemphasis on Emotional Experience
   While emotion isn’t evil, equating spiritual maturity with ecstatic experience has led many into confusion, burnout, or deception.
2. The “Initial Evidence” Doctrine
   Teaching that tongues are the only valid sign of Spirit baptism can lead to spiritual elitism or discouragement for believers who’ve never spoken in tongues.
3. Prosperity Gospel and Word of Faith
   Some Pentecostal offshoots began teaching that faith guarantees wealth and health. This distorted biblical suffering, replacing the cross with consumer comfort.
4. Unbiblical Prophecies and Abuse of Gifts
   Without proper testing (1 Thessalonians 5:21), self-appointed prophets have led many astray. Miracles were sometimes staged or exaggerated, undermining credibility and holiness.
5. Authoritarian Leadership
   In some contexts, “anointed” leaders claimed unquestionable authority—leading to manipulation, financial scandals, or cult-like environments.

Biblical discernment is essential. The Spirit never contradicts Scripture. True spiritual fire sanctifies—it doesn’t sensationalize.

🔄 Lasting Impact on the Church Today

Pentecostalism is no longer a fringe movement—it’s mainstream.

• Today, more than 600 million people identify as Pentecostal or Charismatic, making it the fastest-growing segment of global Christianity.
• Pentecostal churches are especially growing in Africa, Latin America, and Asia, often in poor or persecuted contexts where the power of God is not just desired—it’s desperately needed.
• Worship styles, music, prayer patterns, and preaching styles across denominations have been shaped by Pentecostal influence—even among non-Charismatics.

Yet tensions remain:

• Can emotional expression be balanced with theological depth?
• Can we seek signs without demanding them?
• Can we embrace the Spirit’s gifts without replacing Scripture?

🪞 What Should We Learn — or Repent Of?

1. Recover Dependence on the Spirit
   Too many churches today operate in human strength, strategy, and branding. Pentecostalism calls us back to the Upper Room—to wait, pray, and receive.
2. Pursue Holiness, Not Hype
   The Spirit is holy. Emotionalism, manipulation, and celebrity culture must be renounced. What began in purity can be hijacked by pride.
3. Test All Things
   Not every “tongue,” “prophecy,” or “miracle” is from God. We are called to discern, not despise, the gifts (1 Cor. 14:29; 1 John 4:1).
4. Celebrate the Global Body
   Pentecostalism is a reminder that the Church is not American, European, or white. The Spirit is moving in house churches in China, revivals in Nigeria, and prayer gatherings in Brazil.
5. Don’t Neglect the Word
   Spirit and Word must go hand in hand. Fire without form leads to wildfire. Form without fire leads to dryness. We need both.

📣 Why This Still Matters: Walking Forward in Truth and Power

The story of Pentecostalism is not just about the 20th century—it’s about the Church’s ongoing relationship with the Holy Spirit.

If Jesus is still Lord, and His Word is still true, then His Spirit is still moving.

But how we receive Him—and respond to Him—makes all the difference.

We must hunger for more of God while remaining anchored in His Word. We must celebrate what the Spirit is doing globally, while guarding against excess and error. We must be a people of truth and fire, of Scripture and Spirit, of Christ-centered love and supernatural power.

Let us not quench the Spirit. But let us also not grieve Him.

The Pentecostal explosion shook the Church. Will we let it sanctify us—or simply sensationalize us?

The choice is ours.
