"In Jesus' Name" tells the story of the third stream of Pentecostalism, which emerged during the formative years of the Pentecostal Revival. This is the first comprehensive study of the origins, history and theology of Oneness Pentecostalism, the heterodox movement expelled from the Assemblies of God in 1916 for its rejection of the doctrine of the Trinity and insistence on water baptism in the name of the Lord Jesus Christ.

Reed traces the movement, now estimated at 14 million world wide, to its Pietist and Evangelical roots. Its distinctive doctrine is a radical trajectory of a christocentric reaction that had already begun in early Pentecostalism. Reed's study shows the inadequacy of the label of heresy in light of its thoroughgoing Pentecostal identity and theology of the Name of God.
