I was reading Cornelius van der Kooi’s and Gijsbert van den Brink’s recently released Systematic Theology: Christian Dogmatics: An Introduction. I am really enjoying it. Just as they are getting into a Doctrine of God, with particular focus on God as Trinity, they say this in regard to attempting to do theology as if Karl Barth had never come on the scene:
In our opinion it is impossible (as [John] Frame proposed) to go back to a pre-Barthian nonchristological understanding of the doctrine of God. The Christian concept of God is not generally theistic in nature, with a specifically Christian appendix coming only at the end. From the very start it is determined and colored by the one who was “in the bosom of the Father” and has made him known (John 1:18). In John’s eschatological vision we discover at the center of God’s throne “a Lamb standing as though it had been slain”—a picture of the crucified and risen Christ (Rev 5:6). He is the image of God (Col 1:15), which will apparently determine our view of God in eternity. We should not try to think about God apart from him.
I could not agree more. This is why I have been so drawn to Karl Barth (and Thomas Torrance); what he did was attempt to do theology as if theology could only be done as if Christology happened first. We are Christians after all, and we therefore are to read the Bible and know God in and through Jesus Christ. This something I picked up years prior to coming across Barth, i.e. the idea that the Bible is all about Jesus (cf. John 5.39). This is why I have such a hard time attempting to think theologically alongside so many of my comrades of today in a way that wants to pretend like Karl Barth was never on the scene in a seriously revolutionary way for the theological endeavor; for the church of Jesus Christ in these last days.
As we can see, Kooi and Brink have John Frame in mind as an example of someone who wants to try and do theology as if Karl Barth’s Christ concentrated approach never existed, but there is someone even more contemporary than that (although she fully recognizes the significance of Barth, she just disagrees with his Christological approach). I am referring to Katherine Sonderegger; here is something I wrote about her in review of her ST for the journal Cultural Encounters:
Katherine Sonderegger in the preface to her Systematic Theology, Volume One, The Doctrine of God makes her disdain for the turn to the Trinity for thinking God very clear; she writes: “Perhaps nothing so marks out the modern in systematic theology as the aversion to the scholastic treatise, De Deo Uno. (p. xiv) She believes the Trinity, because of Karl Barth primarily, has taken such pride of place as to crowd out the prime reality that Christian theology first and foremost, when it comes to a theology proper, is a monotheistic faith. She regrets the impact that so called Trinitarian theology has had upon the reality of God’s Oneness; she writes of the De Deo Uno vis-à-vis De Deo Trino, “It belongs not to the preface but rather the body of the dogmatic work to lay out the broad movement in present day dogmatics that has pressed the treatise De Deo Trino to the fore; indeed, it crowds out and supplants the exposition of the One God.” (p. xiv)
If you read her ST in full, it becomes clear that she thinks Barth has gone awry by so focusing on Christology and/or the Trinity as the preamble, as it were, to developing a theological doctrine of God, that she thinks God’s singularity (his “Oneness”) is lost. But again, in agreement with Kooi and Brink, and against Sonderegger, in this instance, as Christians we do not think God in generically theocentric terms, but instead from His Self Revelation in Jesus Christ; in and from the particularity and scandalous reality of the ‘hidden God’ (Deus absconditus) as the ‘revealed God’ (Deus Revelatus) in Jesus Christ. We are Christians not philosophers, per se, after all.
What I am registering in this post is nothing new for me, of course; but I actually believe that what Barth has done has global impact, or it should! As Christians we are ‘people of the Book,’ as such we follow the “narrativity” of Holy Scripture as our ‘lamp’ for introduction to God in Christ. This is what Barth was all about, he simply wanted to follow the Reformed Scripture principle, and because he did his theologizing has been labeled by some as ‘narrative theology’ (Robert Jenson being a student of Barth who has run with that style of theologizing). The approach, in this way, is more hermeneutical than it is metaphysical; it does not deny or ignore the metaphysical, but it reorients things in such a way that the economy of God’s life in salvation history, which has always already found its telos (‘purpose’) in Christ, grounds how Christians should approach God through and through. It prefers to be naïve when it comes to philosophical theology, and instead focuses on biblical theology.
It is more than ironic to me that those in the conservative Reformed and evangelical world (which I myself inhabit) critique Barth as if they are the one’s following the Bible, and Barth was either a heretic, or at least severely heterodox. It is ironic to me that those who claim to follow sola scriptura by the letter want to diminish Barth as a biblical theologian when in fact Barth was the one who was attempting to stick most closely to the text of Scripture, and engage as little as possible with medieval substance metaphysics; i.e. the metaphysics that grounds the theologizing of the conservative Reformed and evangelical types of today. Who is genuinely more biblical in their theologizing than Karl Barth? For my money: no one!
