What they are saying about this book... "Dr. Callen has written with an insight and sensitivity that very few could have brought to this assignment. We are in his debt." --Arlo F. Newell, Editor Emeritus, Warner Press "I judge that this writing will do for the present generation of the Church of God movement what Russell R. Byrum's Christian Theology (1925) did for an earlier one." -- James Earl Massey, Dean, Anderson School of Theology "This outstanding work furnishes pastors, ministerial students, and inquiring laypersons with a substantive resource for the next decades." -- Robert H. Reardon, President Emeritus, Anderson University "This author has a keen understanding of the significant ideas being discussed among today's Christian thinkers. The book not only makes Church of God readers more aware of their own heritage, but also helps them see how their beliefs compare and contrast with those of other traditions." --J. Harvey Gossard, Historian, Winebrenner Seminary "Here is a book that will be helpful to the Church of God movement, to Wesleyan and Anabaptist groups, and to the broader church." -- Howard A. Snyder, Professor, United Theological Seminary - from Amzon
