Still, it seems to me that order is not wholly insignificant. Schleiermacher saved the doctrine of the Trinity for the end, and that is revealing. More recently I've been reading volume 3 of Bavinck's Reformed Dogmatics, and I think it is somewhat significant that he begins his soteriology with a chapter on covenant before moving on to the Person of Christ. It seems to me that this formal order affects the material content. Salvation is a matter of a legal structure, and the importance of Christ is that he makes the legal structure work. I think that is skewed away from the content of the biblical witness. It is striking as well that the covenant idea is read back, in this stream of Reformed theology, into the Trinitarian foundation of the economy, something which I think ought to make us all uncomfortable.
So, without making too much of it, I think the order of theological presentation can matter.
