In The Full Gospel in Zion, Alan J. Clark explores the dynamic history of Pentecostalism in Utah. Although the story of Pentecostalism now spans the globe, there is no previous study of its growth and development among the mountains and valleys of the Beehive State. This book recovers and reveals the identities of the earliest Pentecostal pioneers across the state and places the founding churches within the historical narrative of Utah religion in the twentieth and early twenty-first centuries.

Utah Pentecostals faced difficulties establishing churches and congregations in a region dominated by a Latter-day Saint majority. Pentecostals found that they shared surprising similarities in belief but faced unexpected obstacles in evangelism, as Latter-day Saints did not respond as other Christians did to the Pentecostal message. Clark draws from interviews conducted with church leaders and congregants and from the rich documentary record to show Utah Pentecostals' perseverance in creating a strong foothold in Utah. His work offers a new look at the diversity and richness of Utah's religious history.
