How did the Holiness movement influence the origins of Pentecostalism?

The Holiness movement was a foundational precursor to Pentecostalism, providing both a theological framework and a model for religious experience that early Pentecostals adapted and expanded.1

The Holiness movement emphasized a "second work of grace" following conversion, known as sanctification, which was intended to remove the desire to sin. Early Pentecostal leaders, such as Charles Fox Parham and William Seymour, emerged directly from this tradition. They built upon the Holiness belief in a second blessing by teaching that the baptism of the Holy Spirit was a subsequent, distinct experience evidenced by speaking in tongues.21

Furthermore, the Holiness movement influenced Pentecostalism through:
* Faith Healing: Practices borrowed from Holiness groups, such as the Christian and Missionary Alliance, became a hallmark of the Pentecostal movement.1
* Spiritual Needs: Both movements sought to satisfy the emotional and spiritual desires of people who felt alienated by the formal, middle-class nature of mainstream Protestantism.1
* Evangelical Zeal: The Holiness movement’s focus on revivalism and "heart religion" provided the momentum for the early Pentecostal mission to revive a perceived cold and formalistic church.1
