Barth Conference: Islam and paganism

Having recognised that many of the positions I have come to are very consonant with things that Barth seems to have said, it was interesting to come across an blogged account of a recent conference on Barth:Via Crucis: 2009 Barth Conference: Day 1
Doubly interesting to read this intriguing comment on Islam and Christian faith articulated by Scott Jones: "Barth saw National Socialism as a 'new Islam,' a false ideology led by a false messiah (Hitler). The compelling question, it seems, is why Barth would have seen this connection between Islam and National Socialism as such an obvious one to make. Why does he see Islam as more akin to paganism than to Judaism and Christianity?
After a bit of discussion of Islam's emphasis on revelation vis-a-vis a text (the Koran), the point was made that 'nothing separates Islam and Christianity so radically as the different ways they say the same thing: that there is one God' (CD II/1, 449). There is in Islam a lack of a coming or a becoming of God. This is a point worthy of further exploration, particularly in Christian-Muslim relations."
Absolutely, though I don't think that latter is a new point; what is ponder-worthy is the kinship Barth sees between Islam and paganism (or should that be with a P?). No doubt a shocking thought for many Muslims and others. Nevertheless, I think we need to counterbalance the Abrahamic faiths lumping-together with a recognition that there is an 'odd-one-out' and it is Islam. However, I remain to be convinced the becomingness of God is the differentiator. Certainly since Maimonides (interestingly, writing in an Islamic context), Judaism has tending to understand 'ehad' more like the Islamic 'tawhid' ... and probably for polemic reasons to some degree (but I'm writing beyond my secure competence here, happy to be corrected and further informed). And I would be interested to know, too, what understanding of 'pagan' is being worked with here. The hint is that it would be Aryan revival ideology rather than the more cuddly neo-paganism of earth-centred spirituality in the post 60's west.
