Chicago Cardinal Francis George makes a secularization argument by suggesting it is more difficult for people today to have faith:
Cardinal George acknowledged the pope is concerned about faith, and added that all the cardinals are concerned as well. This will be utmost in their minds when they deliberate in Rome…
“The larger question: Is there now such a sea change in Western culture that people can’t believe; that they aren’t open to belief?” he asked. “That therefore you have to be your own god in a way. ‘You have to do just what you want to do in the way that you want to do it. You have to follow your own dream.’
“Well, it’s important to follow God’s dream.
“So we could say maybe (some) people have lost the gift of faith because we’ve created a society where people can’t believe. It’s impossible — well, not impossible, never impossible, but very difficult — to believe because it goes against the grain to say, ‘I surrender my life.’ Maybe it’s why marriage is in such difficulty because when you’re married that’s what you do. You surrender your life to a woman or a man, a husband, a wife. Well, faith means you surrender your life to God.”
George is suggesting social conditions, “we’ve created a society,” make it more difficult to have faith. He doesn’t suggest exactly why this is. Sociologists and others have made arguments over the years for why this has happened: new technologies, demonstrable progress as well as believing in its capabilities, new ways of thinking (from the Enlightenment on) that favor reason and science, the development of the welfare state that takes care of basic human needs, two world wars, and more.
It would be interesting to hear how the Catholic cardinals discuss this topic as they pick a new pope. On one hand, there are over 1 billion Catholics in the world. On the other hand, Catholics and other Christians have been challenged for decades on the relevance of faith and what position it should play in civil society.
