I just picked up Emil Brunner’s The Christian Doctrine of God, which is his volume one in a series of Christian Dogmatics he has written. While he and I won’t see eye to eye on everything, he’s somebody I can learn from; so expect to hear more from him if you read my blog.
As Brunner starts his Christian Dogmatics out, he of course gives explanation of what Dogmatics actually are. In his giving he offers some profound explication; profound, at least from my perspective, because he explains what in fact Christian Dogmatics represent. His explanation resonates deeply with me, and should help you all to understand where I am coming from as well; i.e. when you read my blog you should know that I am really never attempting to engage in apologetics, but instead always in the work of Christian Dogmatics. Here is what Brunner writes in this regard:
The intellectual enterprise which bears the traditional title of “dogmatics” takes place within the Christian Church. It is this that distinguishes it from similar intellectual undertakings, especially within the sphere of philosophy, as that is usually understood. Our immediate concern is not to ask whether this particular undertaking is legitimate, useful, or necessary. The first thing we have to say about it is that it is closely connected with the existence of the Christian Church, and that it arises only in this sphere. We study dogmatics as members of the Church, with the consciousness that we have a commission from the Church, and a service to render to the Church, due to a compulsion which can only arise within the Church. Historically and actually, the Church exists before dogmatics. The fact that the Christian Faith and the Christian Church exist, precedes the existence, the possibility, and the necessity for dogmatics. Thus if dogmatics is anything at all, it is a function of the Church.
It cannot, however, be taken for granted that there is, or should be, a science of dogmatics within the Christian Church; but if we reverse the question, from the standpoint of dogmatics it is obvious that we would never dream of asking whether there ought to be a Church, or a Christian Faith, or whether the Christian Faith and the Christian Church have any right to exist at all, or whether they are either true or necessary? Where this question does arise—and in days like ours it must be raised—it is not the duty of dogmatics to given the answer. This is a question for apologetics or “eristics”. But dogmatics presupposes the Christian Faith and the Christian Church not only as a fact bu as the possibility of its own existence. From the standpoint of the Church, however, it is right to put the question of the possibility of, and the necessity for, dogmatics.
Thomas F. Torrance briefly describes Christian Dogmatics this way:
Christian Dogmatics – the church’s orderly understanding of scripture and articulation of doctrine in the light of Christ and their coherence in him.
What should be clear from Brunner’s longer explanation, and T.F. Torrance’s shorter one is that Christian Dogmatics is the work of Christians done within the community of the witness of the church of Jesus Christ; as it is pressed up against the reality of its Subject, the living God who is Triune—the ‘God who has spoken’ (Deus dixit).
I am afraid all too many have confused the work of apologetics or “eristics” with the work of Christian Dogmatics; and if they haven’t then they have unfortunately carried over the tools and methods used by apologists, and imported those into the work of Christian Dogmatics. The work of an apologist is largely the work of a philosopher; the work of a Christian Dogmatician is the work of a Christian thinker who self-consciously is working under the pressures of God’s Self-revelation in Jesus Christ. The Christian Dogmatician is not trying to “prove” God’s existence, so he/she can then talk about God; no. The Christian Dogmatician, by definition has already repented and come under the reality of the Christian God in Christ in and through the witness of the church. This is the work I am doing here at the blog; I engage in Christian dogmatic thinking.
One more point of clarification: I do not think a Christian apologist, in the work they do, actually “proves” the existence of the living God; what they do, if anything, is “prove” a god-concept. What the apologist or Christian philosopher should avoid is the conflation of their work with that of the Christian dogmatician; they are definitionally different. What has happened though, unfortunately, is that often this is exactly what happens; over-zealous Christian philosophers and apologists import the concept of god they have “proven” into Christian Dogmatics, and think they are the same God, they aren’t!
In regard to Brunner, one thing that you will notice in his definition of Christian Dogmatics is an emphasis on the Church; he offers a very ecclesiocentric approach to things. I fully appreciate his description of Christian Dogmatics, but I want to be more radical and less neo-orthodox than that; I think the reality that ought to ‘control’ Christian Dogmatics is not the church, but Jesus Christ as the rule. Barth and Brunner have a famous disagreement where Barth gives Brunner a loud Nein when it comes to the possibility of natural theology. Brunner affirms a qualified understanding of natural theology, while as we know Barth famously rejects it. I think we are already getting a bit of a whiff of this difference even early on in Brunner; his emphasis on the church, I think, is a corollary of his commitment to a qualified notion of a natural theology.
