Modernity has abandoned the household gods, not because we have rejected the idolatry as all Christians must, but because we have rejected the very idea of the household. We no longer worship Vesta, but have only turned away from her because our homes no longer have any hearths. Now we worship Motor Oil. If our rejection of the old idols were Christian repentance, God would bless it, but what is actually happening is that we are sinking below the level of the ancient pagans. But when we turn to Christ in truth, we find that He has ordained every day of marriage as a proclamation of his covenant with the church. A man who embraces what is expected of him will find a good wife and a welcoming hearth. He who loves his wife loves himself.

In al-Qaeda we see a terrorist grouping with, in many ways, a medieval ideology, employing today's technology to great advantage. It works in a thoroughly modern way, virtual, amorphous, franchised and unbounded by geography. It has recruited people from all over the world. It understands the power of images, both in its campaign of terror and in its recruitment and proselytising material. It skillfully exploits the instant communications and social networking of the IT age.
