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.

The doctrine of divine simplicity has long played a crucial role in Western Christianity’s understanding of God. It claimed that by denying that God is composed of parts Christians are able to account for his absolute self-sufficiency and his ultimate sufficiency as the absolute Creator of the world. If God were a composite being then something other than the Godhead itself would be required to explain or account for God. If this were the case then God would not be most absolute and would not be able to adequately know or account for himself without reference to something other than himself. This book develops these arguments by examining the implications of divine simplicity for God’s existence, attributes, knowledge, and will. Along the way there is extensive interaction with older writers, such as Thomas Aquinas and the Reformed scholastics, as well as more recent philosophers and theologians.
