All That Is In God (Paperback)

James Dolezal
Reformation Heritage Books


Unknown to many, increasing numbers of conservative evangelicals are denying basic tenets of classical Christian teaching about God, with departures occurring even among those of the Calvinistic persuasion. James E. Dolezal’s All That Is in God provides an exposition of the historic Christian position while engaging with these contemporary deviations. His convincing critique of the newer position he styles “theistic mutualism” is philosophically robust, systematically nuanced, and biblically based. It demonstrates the need to maintain the traditional viewpoint, particularly on divine simplicity, and spotlights the unfortunate implications for other important Christian doctrines—such as divine eternality and the Trinity—if it were to be abandoned. Arguing carefully and cogently that “all that is in God is God Himself,” the work is sure to stimulate debate on the issue in years to come.

“This is a significant book on a topic that could hardly be more important. What we believe about the nature of God matters, and we dare not risk having an underdeveloped or sub-biblical understanding of such a central Christian concern. To put it as plainly as possible: I want every one of our students to read this book and to reflect deeply on its teachings, since what Dolezal seeks to explain is nothing less than the historic doctrine of the Christian church.”

—Jonathan L. Master, Professor of Theology and Dean of the School of Divinity, Cairn University

“All That Is in God: Evangelical Theology and the Challenge of Classical Christian Theism offers an exceptionally clear, concise, and compelling presentation of what, until recently, catholic Christians have believed and confessed regarding the being and perfection of the triune God. It also offers incisive analysis of much contemporary evangelical teaching about God, concluding that both conservative and progressive ‘theistic mutualists’ share common assumptions and fallacies regarding the being and activity of God. I know of no other contemporary book that makes both of these contributions together in one place, and certainly not with the degree of clarity, charity, and persuasiveness that Dolezal’s book exhibits. A worthy book that deserves a wide readership!”

—Scott R. Swain, President and James Woodrow Hassell Professor of Systematic Theology, Reformed Theological Seminary in Orlando


“The road to doctrinal decline is not a steep cliff but a gradual descent. Before we realize it, we have altered or abandoned long-cherished beliefs and doctrine. James Dolezal sounds the alarm on the important but forgotten doctrine of divine simplicity. He calls the church back to its traditional understanding and creedal affirmations not because he fears change, but because they are biblical. This book is well worth the time to read, digest, and reinvigorate our understanding of the simplicity of God.”

—J. V. Fesko, Professor of Systematic and Historical Theology, Westminster Seminary California
