While tracing the rich historical development of the Reformed doctrine of the covenant, Geerhardus Vos zooms out to scan the big picture and asks, “To what, then, does one attribute the fact that from the beginning this concept of the covenant appears so much in the foreground of Reformed theology?” Vos’ answer? Christian cosmology demands the covenant.
As the Reformers turned to the Scriptures during the Protestant Reformation, Vos argues that they found there a hermeneutical key which unlocked the majesties of Christian doctrine and unified the Christian worldview:
This root idea which served as the key to unlock the rich treasuries of the Scriptures was the preeminence of God’s glory in the consideration of all that has been created. . . . God does not exist because of man, but man because of God. This is what is written at the entrance of the temple of Reformed theology.
(Quotes from Redemptive History and Biblical Interpretation: The Shorter Writings of Geerhardus Vos, ed. Richard Gaffin, pp. 241–42)
The glory of God provided the context for all of Reformation theology. Just as the beginning of a story sets the idealogical landscape for everything else within that story, so the context established by Christian cosmology–a cosmology of the triune, personal God creating the cosmos for his own glory–sets the stage for all of Christian theology and philosophy. (Compare the opening lines of these two short stories: (a) In a galaxy far, far away. . .; (b) Last Thursday evening at Starbucks…. The beginning sets the stage for all that follows in terms of characterization, plot development, etc.)
From this doorpost of the temple of Reformed theology, Vos draws out the following necessary deductions:
- All of man’s work has to rest on an antecedent work of God;
- In all of his works man has to show forth God’s image and be a means for the revelation of God’s virtues;
- The latter should not occur unconsciously or passively, but the revelation of God’s virtues must proceed by way of understanding and will and by way of the conscious life, and actively come to external expression. ((Redemptive History, 242.))
From Vos’ perspective, out of these basic cosmological demands flows the doctrine of the covenant: “We hope to show how this threefold demand has been reckoned with precisely in the doctrine of the covenant.” (To follow Vos along as he explains how this is so, tolle lege–take up and read!)
Those of us daring to humbly dawn the banner of “Reformed” would do well to remember the doorpost of the temple of Reformed theology–the glory of God. And those of us seeking to taste of the rich covenantal marrow of the Scriptures would do well to remember that Christianity’s cosmology drives, yea demands, its covenant theology.
