To begin this post, I would simply like to quote a section from Christopher Green’s book Doxological Theology in which he examines Karl Barth’s formulation of the doctrine of divine providence in strict accordance with the inner theo-logic of the Apostles’ Creed (after which I will conclude with a few comments of my own):
It is germane to Barth’s doctrine of providence that he should argue that the first article of the creed must be read in the light of the second, and so he states this criterion for his doctrine in a number of key places in III/3…
In the second article of the creed one finds the true meaning of the first, that God the Father of Jesus Christ is the “Almighty.” This correction of the creed is the “climax of the whole doctrine of creation.” For Barth, the previous generations that recited the creed in full should have, so to speak, “known better” than to accept a philosophical version of simplicity, as the second article puts Christ’s face on the first. This makes the God of providence, that is, the God of the first article, identifiable as noncapricious. Barth consistently argues in 1949 that, despite the creed, the God of Western theology on the whole is unfortunately a philosophical monad, “the absolute, the general, the digit 1.” In this volume, he states that the most common cause for this dogmatic distortion is confusion between divine unity and simplicity. The default Western position on simplicity, he says, is grounded in an analogia entis which contrasts God with the world by identifying him as a philosophically “simple” being. Barth often raises this complaint about the Western view, which is implicit in his critique of J. P. Sartre, whose concept of man, he says, is a displaced version of the generic god of the West:
It is as man that man assumes the functions of deity, and in spite of the strangeness of his form is clotted with the attributes of at least the conventional Western conception of God, existing of and by and for himself, constituting his own beginning and end as absolute actuality without potentiality, unique, omnipotent, and certainly omniscient […] All that is lacking is the slightest trace of the biblical concept of God. [CD III/3, pp.342-343]
It is the Apostles’ Creed that points to God’s election in Jesus Christ in its summary of the whole of Scripture, safeguarding the God of providence as the triune God. According to Barth, the doctrine is commonly obscured when God’s power as “Father” is abstracted from his revealed work in Christ. Thus, the God who reveals himself in an undivided way is slighted, severing the One who is the Son from his constitutive relation with the Father. Against this, Barth states at the beginning and end of his writing the Church Dogmatics that “the theological rule with respect to the Trinity [… is] opera trinitatis ad extra sunt indivisa.” For Barth, his commitment to the unity of the triune God means an approach to divine providence will not be grounded in a metaphysical concept of the simple. Rather, he apprehends the work appropriated to the second person of the Trinity (i.e., election, reconciliation) as a context for understanding the variegated unity of the triune Subject who acts providentially. It is not hard to see, then, why Barth chides his opponents in III/3 for not “deducing” providence from the doctrine of the Trinity. As Barth sees it, his predecessors lost the programmatic role that should be played by the triunity of God because they failed to understand the doctrine of predestination in the context of the person and work of Christ. This is the purpose of the second article of the creed, which should have been sufficient for pointing to the centrality of Christ, and consequently, to the triunity of God. It is in the second article that the hidden God becomes manifest.
What I find immensely helpful about this is the way in which Barth, via Green, uncovers the fundamental “theo-logic” (i.e. the unique logic that accords with the way of God’s self-revelation in Christ) that underlies the various affirmations of the Apostles’ (and one could say the same of the Nicene-Constantinopolitan) Creed. This underlying theo-logic is signalled in the very first words of the Creed that recognize God as “Father” before identifying him as “Creator”. This is highly significant in that it gives a distinctly trinitarian and christological shape to the Creed’s reading of Scripture. The Creed interprets the “God” who “in the beginning…created the heavens and the earth” (Gen. 1:1) not as, in Green’s words, a “philosophical monad” but rather as God already existing as the Father of the Lord Jesus Christ. On this basis, Barth rightly discerns that a proper understanding of the Creed, and through it a proper interpretation of the biblical witness, is that the first article – that affirms God as Creator and Sustainer of creation – must be read strictly in accordance with the second article concerning the person and work of Jesus Christ. Another way of saying this would be that the Creed affirms the trinitarian election of Jesus Christ – the divine determination to not be the Father of the Son and the Son of the Father through the Spirit apart from enlarging that communion to include, through the incarnation of the Son, human creatures in the overflow of the triune life, love, and light – as the beginning of all the ways and works of God.
Thus, if we are to remain (apart from compelling reasons not to do so) faithful to the universal consent of the early church, set forth in the Creed, regarding the essential content of the Christian faith, we must learn, as Barth did, a rigorously Christ-centered hermeneutic that does justice to the election of Christ as the ground, means, and goal of all that Scripture teaches. In relation to the doctrine of providence, this means that we do not merely have a God as Creator who rules over creation and governs it according to his will, but a triune God who relates to his creation and exercises his providence over it primarily as loving and gracious Father who orders all things by his Spirit towards their intended summation in Christ (Eph. 1:10). To know this is to rest secure, as question 26 of the Heidelberg Catechism states:
That the eternal Father of our Lord Jesus Christ, who out of nothing created heaven and earth and everything in them, who still upholds and rules them by his eternal counsel and providence, is my God and Father because of Christ the Son. I trust God so much that I do not doubt he will provide whatever I need for body and soul, and will turn to my good whatever adversity he sends upon me in this sad world. God is able to do this because he is almighty God and desires to do this because he is a faithful Father.
