Pentecostalism is one of the most dynamic forces in twentieth-century Christianity. From fast-growing denominations such as the Assemblies of God to popular television ministries such as "The 700 Club," the fruits of Pentecostalism can be seen throughout modern Christian life.
In this landmark study, Donald Dayton explains how Pentecostalism grew out of Methodism and the nineteenth-century holiness revivals. He finds evidence of Wesleyan teaching in the classic writings of many Pentecostal leaders. He shows how Pentecostalism is rooted in the Wesleyan theological tradition, rather than being a contrived system of modern revivalistic ides. Martin E. Marty says in his foreword that Pentecostals "have no choice, it is clear from this book, but to see that there were . . . roots to the growth they reaped." He calls "Theological Roots of Pentecostalism" "a very important statement . . . one without which subsequent commentators on Pentecostalism are not likely to give intelligent accounts."

The Wesleyan tradition of the 18th century and its related movements has had a global impact that has often been understated and underestimated. Charles Yrigoyen, Jr. presents a diverse collection of essays that document the Wesleyan traditions from founder John Wesley's preaching across Great Britain to his followers' spread of Methodist views throughout Latin America, Asia, Africa, Australia, and Europe. Through a series of essays, The Global Impact of the Wesleyan Traditions and Their Related Movements documents the influence of Methodist missionaries on peoples and religions throughout the world. The text is divided into three parts: Part I includes four essays about basic missiological and methodological issues; Part II includes 15 essays that illuminate the global impact of the Wesleyan traditions and related movements on topics such as independent churches in Africa and the Hwa Nan College in China; and Part III describes the resources for researching and extending the global impact of traditions of Wesley's works, such as the Obras de Wesley (the Spanish version of Wesley's works) and the valuable collection of Wesleyana and Methodistica materials at the John Rylands University Library in Manchester, Great Britain. Diverse in scope, The Global Impact of the Wesleyan Traditions and Their Related Movements is a comprehensive volume for religious scholars and historians interested in the Wesleyan traditions.
