How does God’s unchanging nature impact the salvation of his people?

While divine immutability enjoyed a broad affirmation through much of Christian theological antiquity, it has fallen on harder times in modernity. Seen as a holdover from overly philosophical theology, divine immutability has often been characterized as rendering God static and incapable of having meaningful relationships with his creation.


This book aims to swim upstream from this claim and demonstrate that divine immutability does not handicap soteriology but is a necessary and vital component of God’s economy of redemption as triune changelessness protects and promotes the redemption of God’s creatures. By anchoring the economy of redemption in divine immutability, we see the benefit of rooting all of God’s economic work in the immanent life of God.

This book aims to be a work of dogmatic theology and therefore will arrive at this thesis by way of exegetical, historical, and philosophical theology. In harmony, these fields will interact with varying deviations and denials of divine immutability and ultimately conclude that a classical articulation of God’s changelessness does most justice to the economy of redemption.

About Ronni Kurtz

Ronni Kurtz (PhD, Midwestern Baptist Theological Seminary) is an Assistant Professor of Theology at Cedarville University. He is also the author of ‘Fruitful Theology: How the Life of the Mind Leads to the Life of the Soul’.



Traditionally, from the time of the Church Fathers, the immutability of God was universally held.  In the twentieth century, many philosophers and theologians rejected this doctrine.  Rather, they argued that God must be conceived as mutable and passible. However, presently there is a theological resurgence defending and promoting God’s immutability – both among Catholic and Protestant theologians.  Ronnie Kurtz is one of those theologians who admirably represents this retrieval.  He creatively and insightfully argues that the biblical, historical and theological traditions rightly profess God’s immutability.  Far from be a hindrance, divine immutability is the sine qua non for humankind’s salvation.  Thus, Kurtz makes a profound contribution to the Christian theological and philosophical tradition.

This careful work is a shining example of an encouraging trend.  A rising generation of evangelical scholars has rediscovered the primary sources of our common catholic heritage.  Not only liberals but some influential evangelical theologians have rejected key aspects of God’s immutability, often misunderstanding even the definition, exegetical basis and historical development.  This is a terrific articulation of what Christians mean when they affirm the words of Malachi 3:6: ‘For I the LORD do not change…’  And, as Ronni Kurtz points out well, this unchangeable nature and purpose is good news for us: ‘…Therefore, O Israel, you are not consumed.’
