This book explores the polarizing and divisive views of patriotism and pacifism as they impacted upon the early Pentecostal movement in Britain at the time of the Great War (1914-1918) and in the years immediately following. A critique is offered on the different views of two leading characters within early British Pentecostalism.Alexander Alfred Boddy (1854-1930), was the acknowledged father of early Pentecostalism in Britain. He was an ordained, long-serving, Anglican minister. Boddy published and edited a popular Pentecostal newsletter, Confidence, from 1908 through to 1926. Boddy was a patriot, and his patriotism is assessed through a study of aspects of his life, ministry, and writing.Arthur Sydney Booth-Clibborn (1855-1939), was the son-in-law of William Booth, the founder of the Salvation Army. Booth-Clibborn was a prominent figure in the Salvation Army in Europe and later within early Pentecostalism. He was a lifelong pacifist and wrote an important book on the subject, Blood Against Blood. Booth-Clibborn's Christian pacifism is examined through aspects of his life, ministry, and writing.The opposing views of Boddy and Booth-Clibborn are critiqued and act as a catalyst for the discussion that underpins this book. Their legacy is also assessed.
