Via Young Hegelian is this article in the Guardian. While I think it overreaches, it's still very interesting. A snippet:
Nicene Christianity is the religion of Christmas and Easter, the celebration of a Jesus who is either too young or too much in agony to shock us with his revolutionary rhetoric. The adult Christ who calls his followers to renounce wealth, power and violence is passed over in favour of the gurgling baby and the screaming victim. As such, Nicene Christianity is easily conscripted into a religion of convenience, with believers worshipping a gagged and glorified saviour who has nothing to say about how we use our money or whether or not we go to war.....
[T]he Nicene religion of the baby and the cross gives us Christianity without the politics. The Posh and Becks nativity scene is the perfect tableau into which to place this Nicene baby, for like the much-lauded celebrity, this Christ is there to be gazed upon and adored - but not to be heard or heeded.
