The “Living Immutability” of God
Trinity and History in the Theology of Isaak A. Dorner
How does the doctrine of divine immutability square with the revealed vitality of God? This is the question that Lutheran mediating theologian, Isaak A. Dorner, put forth in his three-part essay for the Jahrbücher für deutsche Theologie, “On the Proper Conception of the Doctrine of God’s Immutability, with Special Reference to the Reciprocal Relation between God’s Suprahistorical and Historical Life” (1856–58). I begin with Dorner’s immutability essay as a way to frame the central problem of this study. The problem derives from a modified version of the question above on bridging divine immutability with God’s revealed vitality as well as, mutatis mutandis, reconciling God’s unchangeability with the living character of God’s being. I ask: How does the eternal nature of the Trinity square with the revealed vitality of God? Specifically, how does the triunity of God’s being ground and enable God’s living relation to history? The scope of these questions will include treatments of Trinity’s significance for examining divine presence, the movement of God in time, the relation between divine transcendence and immanence, and the formulation (and reformulation) of divine attributes, such as divine immutability.
This chapter, however, presents more than a mere overview of Dorner’s immutability essay that frames the basic problem of this study. My way to this problem comes through a critical engagement with the role of Trinity in Dorner’s immutability essay. I argue that Dorner applies the trinitarian understanding of God more consistently to the latter of the two problems posed above; that is, he constructively applies Trinity to the problem of reconciling immutability and the vitality of God’s being. This opens up a dynamic ontology for understanding how God relates to history through God’s triunity. But Dorner does not similarly employ Trinity for the other problem of reconciling immutability with the revealed being of God in history. The meaning of Trinity for the history that God lives with others is largely left unsaid. This lacuna in Dorner’s application of a trinitarian ontology to the God-world relation marks a gap that I attempt to fill out in subsequent chapters through engagements with the other central figures of this work. Furthermore, Dorner’s essay plays a significant role when we turn to Karl Barth’s trinitarian theology in chapter 2. While the immutability essay garnered little attention in the theological scene of Dorner’s time, it was given something of a historical lifeline shortly before the middle of the twentieth century when Barth noted his indebtedness to the work in his doctrine of God from Church Dogmatics II/1. In chapter 2 I use Dorner’s essay for two purposes: first, as a key point of comparison in the critical assessment of how Barth’s trinitarian theology construes God’s living relation to history; and second, to demonstrate the importance of election for a concept of immutability that includes both God’s eternal vitality and being in time.
Dorner’s constructive proposal centers on his concept of God’s ethical being in part III of the essay. In order to understand both how Dorner arrives at this notion as well as the underlying problems he identifies in the doctrine of immutability, and the role Trinity plays in fixing them, it is important to consider the immutability essay more broadly. In section 1 of this chapter I lay out Dorner’s objection to the classical understanding of immutability. Next I unpack Dorner’s initial use of trinitarian doctrine to conceive of the liveliness that underlies God’s immutability, giving specific attention to the way Dorner relates this concept to God’s involvement in creation. I then turn to Dorner’s trinitarian understanding of God’s ethical immutability. Section 2 of this chapter concludes with a critical analysis of Dorner’s account that derives the central problem of this study by recasting Dorner’s task in the immutability essay along more robustly trinitarian lines.

1.1: The Context of the Immutability Essay
Dorner’s immutability essay is occasioned by the kenotic controversy of the mid-nineteenth century. In part I of the essay Dorner assesses this controversy. The debate, mainly between Lutheran and Reformed theologians, laid claim to the concept of the communicatio idiomatum or the communication of properties that belong to the distinct natures (human and divine) of Christ’s person. A key Lutheran figure in the debate, Gottfried Thomasius, advanced the idea that the incarnation of the Logos entails not only the non-use but the actual divestment of certain divine attributes. The Logos surrenders the relative divine attributes, or those that pertain to the divine essence in the being and activity of God ad extra (e.g., omnipotence, omnipresence) and not the necessary attributes of God such as divine love and wisdom.
Dorner is severely critical of Thomasius’ Christology. Thomasius wants a conceivable account of the unity of divinity and humanity in Christ’s person. But to achieve this by way of a self-divestment of the Logos’ divine attributes, Dorner argues, comes at the expense of one of the very things that Thomasius wishes to uphold within the unity of Christ’s person: his deity or divine nature. Consequently, “it is not the immanent eternal Son of God, but only another, naturally subordinate ‘great man’ that becomes incarnate.” Moreover, Dorner takes issue with a problem that he finds endemic to the kenotic project of his contemporaries as a whole. On one hand, they dwell on a “fixed unity” between the Logos and humanity that begins at the outset of the Son’s incarnation; on the other, this unity is conceived as a goal to be attained over the course of Christ’s life. The kenoticists therefore assume an idea of divine immutability, in this case, one that dictates the terms of Christ’s personal development in time, which they otherwise oppose. Dorner’s dissatisfaction with the kenotic project is, however, only mildly telling of his larger aims. His constructive proposal around divine immutability becomes more clear through his foray into the doctrine of God in part II of the essay.
