What does it mean to be "theo-centric"? It's a fine aim - it's the only aim really for Christians. But here are some things to think about when someone urges us to be God-centred...
First we should ask: Which God are we talking about?
The person who cries 'God-centred' the loudest is not necessarily the most biblical. (Nor is the person who cries 'biblical', but that's another story). The absolutely key question is what kind of God is central to our thinking. And that question is not resolved in the slightest by saying He's central. In fact to say that 'God' is central to our theology is basically a tautology.
As Simone Weil says:
"No human being escapes the necessity of conceiving some good outside himself towards which his thought turns in a movement of desire, supplication, and hope. Consequently, the only choice is between worshipping the true God or an idol."
We're all God-centred. The question is, which God?
I have little patience for theologians or bloggers who claim a superiority because they are 'God-centred'. Often it's accompanied by the accusation that their opponent is 'Man-centred'. (And one of these days I'll write a post about how they're both wrong - we should be 'God-Man (i.e. Christ)-centred'). But really, in Simone Weil's sense, we're all 'God'-centred. What we really have to do is sort out who this God is who is central to our thinking.
But let's note well: the fact that our theology should be (and, in a sense, always is!) utterly consumed by and radically focussed upon God, in no sense tells you whether God Himself is consumed by and focussed upon Himself. Those are two entirely separate questions.
One is about our theological method, the other is about the 'theos' who, of necessity, stands at the centre of it.
Of course we should have our hearts and minds fixed on the living God, and of course if we fixed our ultimate affections elsewhere that would be idolatry. Ok, great. What bemuses me is the claim that God Himself must fix His affections on Himself lest He be an idolater too. Do you see how theo-centrism as a theological method gets confused with theo-centrism as a doctrine of God? And that gets confused with theo-centrism as God's doctrine of God!
More dangerously, do you see how such a method is in fact anthropocentric? It's an argument that says 'We would be idolaters to set our affections on lesser beings, so God must be an idolater if He did that.' It's a theology from below. And yet I find it on the lips of the very people who want to accuse all around them of man-centredness.
So let's be clear - everyone is already God-centred in their theology. The real issue is what kind of God we're talking about. And the question of theo-centric method does not at all settle the question of God's own being. While we must be theo-centric, we have to admit that God Himself is higher than the 'musts' that apply to us. The theologian who says God "must" love Himself higher than the creature has actually followed a logic that is less than God-centred.
We do not by nature know the kind of being that God is. And we cannot reason it out from the basis of how we find life as creatures. To tell a person that 'God' must be at the centre of their thinking will not tell them anything really. God cannot be assumed from the outset, He must be revealed.
The fact that all the gods of human religion are self-centred means nothing. The fact that we are called to be 'God-centred' means nothing for God's own life and being. It neither means that God should be centred on us, nor on Himself. The question of His own being is the key question and it can only be resolved as God reveals Himself.
