I think one very annoying feature of many of the present group of cheerleaders for atheism is the idea that somehow if we get rid of religion as a society we will simply all become cheerful humanists, and take all of what we put into God and put it instead into ourselves, thus being so much the better off.
In fact, I think that while atheism in itself is not a threat to the future of civilization, I think that a belief in what I will call the secular paradise is perhaps the most destructive idea that we can have, and will bring down civilization if people who believe in it have enough political power. The Christian heaven is not of this world, and it can't be achieved by the exercise of political power, although Christians have, throughout history, attempted to use political power for what they have taken to be divine purposes. The results have typically left black marks on the history of Christendom. Nevertheless, if Christianity is true, there are limits on what we humans can do to bring in the Kingdom of God. Religious belief, for many of us, needs to be a choice, and God is ultimately in control, not us. But the secular paradise is to be achieved my man and his own efforts. The end is noble, and it thus justifies whatever means we might use to get there. It is the combination of atheism and belief in the secular paradise that leads to the kinds of horrors we saw from the Communists.
I do not know whether the author of this essay is an atheist, but it is entitled "Where are all the honest atheists."
