Vanguard Professor Ed Rybarczyk Has New Book Published

Dr. Ed Rybarczyk ‘85, an associate professor of systematic theology who specializes in Eastern Orthodox theology and Pentecostal-Charismatic history, has just released his new book entitled The Spirit Unfettered: Protestant Views of the Holy Spirit.

The book explores a comparison of Protestant views on the Holy Spirit with Roman Catholic and Eastern Orthodox models, while also delving into the important theologians and figures in Protestant tradition, including Martin Luther, the Anabaptists, John Wesley, Friedrich Schleiermacher, Abraham Kuyper, Karl Barth, Jurgen Moltmann, Wolfhart Pannenberg, Clark Pinnock and Michael Welker.

“This book shows how theologians have responded to and interacted with the philosophical changes attributed to the Holy Spirit throughout five hundred years. It is written for undergraduates and lay people to show them how theology impacts the faith and the Christian life of billions of people,” says Rybarczyk.

Rybarczyk, who is also an ordained Assemblies of God minister and a graduate of Fuller Seminary, has published one other book, Beyond Salvation: Eastern Orthodoxy and Classical Pentecostalism on Becoming Like Christ, a book that won the annual Pneuma Award in 2005. Along with Dr. Eric Patterson, Rybarczk also co-edited the book The Future of the Pentecostal Movement in the United States.
