18 For this reason therefore the Jews were seeking all the more to kill Him, because He not only was breaking the Sabbath, but also was calling God His own Father, making Himself equal with God.
After writing bloggy theology for so many years you start to wonder who you are writing for. Personally, I have always really written for myself in an attempt to articulate unarticulated thoughts racing around in my head. Writing helps to provide a semblance to my thoughts, and thus blogging turns out to be a great outlet in an attempt to bring order where there is only disorder (in my head) in regard to the various themes and theological loci running wild in my personal universe.
The previous paragraph was simply a notation of how I often feel when I write a blog post. I usually (as you know) just reflect on whatever I’m reading at the moment. Often I refer to theological antidotes that require some sort of theological context in order for the antidote to be seen as an actual need. But because of space limitations (because of this medium) I don’t have the time or space to problematize things to the point that my posts come with the sort of gravitas they actually do have in their particular contexts. This said: this post has to do with Jesus’ deity and its significance towards understanding who God is, and how it is that we come to know who God is. I’m not really sure these sorts of issues press upon the evangelical psyche in North America these days. I’m not really sure doctrinal matters matter anymore; that the average evangelical really gets how significant sound doctrine is. I’m not sure evangelicals really grasp that they are supposed to care about sound theological reflection; I’m pretty sure most evangelicals don’t even realize that there is such a thing as sound theological reflection, or that they’ve even heard of such grammar. For the average evangelical the deity of Christ is a given, but because of the lacuna of doctrinal teaching in the churches I’m almost positive that even this ‘given’ is no longer understood as such (that is if you asked the average evangelical to explain why the deity of Christ matters in regard to salvation and other important things).
In an attempt to help assuage some of the evangelical absence, when it comes to being mindful of the most important doctrinal matter we could imagine, I wanted to offer a quote from Karl Barth (most evangelicals, these days, don’t even realize that they should be “afraid” of Barth) with reference to the significance of the deity of Jesus Christ and how that relates to his humanity. You will note in this quote that Barth is addressing some ancient Christological heresies, namely ebionitism and docetism, respectively. Barth is pressing home what is noted in John 5.18 (etc.), and grounding the Son’s relationship to the Father as the basis for appreciating the type of Revelation that occurs in the Son become human. Of note, at least by implication (in my mind), is the way Barth understands deity; you will see that it is necessarily trinitarian, and thus not a philosophical concept of the Divine reality. Here I am pressing against a methodological turn that has developed in the history of theologizing; viz. the way Christians have deployed philosophical imagination towards conceiving God (or not). I’d suggest, stringently, that we not rely on philosophical imagination as the primary means by which we think Godness, but instead rely upon God’s special Revelation of Himself in Jesus Christ as sufficient for imagining the verities of who God is. Barth writes:
Jesus is Lord—this is how we think we must understand the New Testament statement in concert with the ancient Church—because He has it from God whom He calls His Father to be the Lord, because with this Father of His, as the Son of this Father, as “the eternal Father’s only child,” He is the Lord—an “is “ which we deny if we are unable to affirm it with those who first uttered it, yet which cannot be deduced, or proved, or discussed, but can only be affirmed in an analytic proposition as the beginning of all thinking about it. In distinction from the assertion of the divinisation of a man or the humanisation of a divine idea, the statement about Christ’s deity is to be understood in the sense that Christ reveals His Father. But this Father of His is God. He who reveals Him, then, reveals God. But who can reveal God except God Himself? Neither a man that has been raised up nor an idea that has come down can do it. These are both creatures. Now the Christ who reveals the Father is also a creature and His work is a creaturely work. But if He were only a creature He could not reveal God, for the creature certainly cannot take God’s place and work in His place. If He reveals God, then irrespective of His creaturehood He Himself has to be God. And since this is a case of either/or. He has to be full and true God without reduction or limitation, without more or less. Any such restriction would not merely weaken His deity; it would deny it. To confess Him as the revelation of His Father is to confess Him as essentially equal in deity with this Father of His.
Barth is making an unusually syllogistic case for the deity of Christ; typically it is more paradoxical (or dialectical sounding). But what stands out is the way Barth ties the deity of Christ to the Father-Son relationship. If the Father is God, and the Father is indeed the Father, then this implies a Son; if the Son is the Son of the Father, then like the Father the Son is equally God. This seems rather straightforward reasoning, except for the fact that we are thinking a primordial reality that stands behind and not after how we think Father-Son (or offspring) relations. What comes through most sharply is that only God can reveal God; as such it is significant to understand just what is taking place in the Incarnation. It isn’t a projection of God into the world; it isn’t a projection of the world into God; it is God revealing Godself in the eternal Son as the express image of the relation He has always had as the Son of the Father by the communion-ing of the Holy Spirit.
I have never ever heard such verities referred to from the pulpits of evangelical churches. I have heard such pulpits wax eloquent about how they believe that the Son is both God and Man; but I have never heard that explicated with depth from evangelical pulpits. The most I’ve heard from evangelical pulpits, in this regard, is when they have a special speaker come and offer a primer on how to engage with Jehovah’s Witnesses and Mormons; but that is not what we are doing in this post with Barth. Christians need to understand the majesty of the God with whom they have to do. They need to have their minds blown by the concrete realization that their salvation and very breath is contingent upon the grace that God is and has become for them in His entrance into the fallen humanity of fallen humanity and from thence redeeming life anew in resurrection splendor. But evangelicals really have no time for this; at least most of the pastors don’t. If anything, evangelical pastors, if they are being tempted to think more deeply, are being shanghaied by the ‘retrieval’ movement wherein philosophy not Revelation serves as the bases by which they think they must think deeply about God.
