The Emergence of Pentecostalism in Wales: A Historical, Theological Evaluation of the Early Development of the Assemblies of God Denomination in South East Wales British Pentecostalism is linked to the Azusa Street Revival in Los Angeles through T. B. Barratt and Anglican vicar Alexander A. Boddy at Sunderland. Boddy's experience and subsequent ministry set the foundation in Britain for the rise of the Apostolic Church, the Elim Church and the Assemblies of God. Each of these Pentecostal denominations had their roots in Wales. Following the Welsh Revival of 1904-05 some (enthused by their experience) sought a deeper relationship with God; and this search ultimately led them to Pentecostalism. A group of eager believers emerged around the town of Crosskeys in South East Wales. By 1912 they had established the Crosskeys Full Gospel Mission, which soon became a centre for Pentecostal activity. The central role of the Crosskeys group is seen in the development of the Assemblies of God in Wales and Monmouthshire denomination which was in existence by 1921. The Crosskeys based group had been in correspondence with the American Assemblies of God (AG) regarding joining that denomination as an official presbytery. It was this action that caused a group of like-minded English Pentecostals to pursue the establishment of the Assemblies of God in Great Britain and Ireland in 1924. This British denomination incorporated some thirty-eight Welsh Pentecostal assemblies. This book considers some of the important theological, political and social influences which shaped the brand of Pentecostalism that emerged in South East Wales in the early twentieth century--a movement which was to have a wide ranging influence on subsequent Pentecostal history far beyond the borders of Wales.
