This book focuses on the transformative journey of Methodism and tackles a profound question: How did a radical revival movement evolve into an established mainstream Church? With a global family of around eighty million, Methodism and its Holiness offshoots have come a long way since their origins as a fervent revival within the Church of England in the late 1730s. Once perceived as controversial and charismatic, early Methodists, led by John and Charles Wesley, preached salvation to unruly crowds, often facing fierce opposition. Despite its turbulent beginnings, the Wesleys skilfully kept the movement anchored to its Anglican roots, preventing it from fracturing entirely. This allowed Methodism to evolve into an established church while maintaining its distinct identity. The volume delves into the enduring legacy of early Methodism, exploring its theological influences and developments over time. With its identity wrapped up in dual focus on mission and holiness, Methodism's impact on global Christianity is profound. From the Holiness movement to the rise of Pentecostalism, its early radical and charismatic practices still resonate in the Church today. Featuring essays from leading Wesleyan scholars, this book is valuable for anyone interested in the dynamic history and lasting influence of the Methodist tradition.
