I think that it's highly likely that the Christian God represents a sort of idealised Roman Emperor. After all it was Emperor Constantine (reigned 306 - 337) who adopted Christianity as the official religion of the Roman Empire. It's probable that, by Constantine's day, the empire was getting too big and difficult to control. Then Constantine went and compounded his problem by moving his capital to the shores of the Bosporus on the eastern fringe of the empire (presumably, a typical rich and powerful man's vanity project). Then he - or more likely his brilliant advisers - came up with the idea of using religion as a means of social control. They searched around and discovered an obscure middle eastern cult called Christianity - which, hitherto, they had been persecuting. They realised that this religion had all the elements that they were looking for: it was monotheistic (one God = one Emperor), and contained a lot of a rather peculiar bullshit about 'sin' and 'sacrifice'. The Christian God was wise, all-powerful and all-seeing (which Constantine probably wished that he was) and all of the sin-n-sacrifice stuff served to keep the population on the 'back-foot' and more focussed on the fates of their immortal souls than they were on rebellion.
So I suspect that Christians are still, in effect, submitting to the will of Constantine! Well, lads, you can stop now - he's been dead for 1678 years!
