Some atheist friends of mine keep saying this Pope faces a daunting challenge not faced over most of the 2000 years since a hastily assembled collection of short stories made it onto the bestseller list: the march of science. There was a time when the church could just impose rules and people knew they had to live by them because heaven or hell awaited. They knew this to be true because there were no alternative narratives. Sure, there were competing sects but these said pretty much the same kinds of things: god is in charge, do what we tell you he says. In the last 100 years, science has looked at the cosmos and found no god; it has looked back to the beginning of time and found no god; it has considered the building blocks of matter and found no god; and it has considered the formation of life and found no god. It is almost as though there is no god. The harder the church makes it to be a Christian the greater the incentive to accept what science is saying: that god is how people understood the world before people understood the world.
But I prefer to think otherwise.
