In 1968, the Methodist and Evangelical United Brethren (EUB) churches merged to form The United Methodist Church.  More than forty years later, many United Methodists know very little about the history, doctrine, and polity of the EUB. To be sure, there are vestiges of the EUB, most notably the Confession of Faith, in the United Methodist Book of Discipline, but there is much more to be profitably explored. For example, the EUB represents a strand of German Pietism that developed an emphasis on the work of the Holy Spirit in the life of the church that, with the exception of Wesley, Fletcher and the early Methodists, was unparalleled in the history of Protestantism. This book makes accessible to clergy and laity alike the considerable riches of the EUB tradition with a view toward the renewal of United Methodism today.
