I think that the concept of religion has evolved a lot between the 20th and the 21st century, also thanks to Ecumenism and to Interfaith Discussion (and to RF..lol)
But one wonders: why is atheism on the rise, especially in Europe? I think it's because people have realized that religions are nothing but a "cultural product".
I am also convinced that the term religion comes from Latin res legere...that is, to cultivate a sort of ritualism. The real religion is the personal one, the one you create by yourself by understanding the world. And I think that being atheists help you understand your path,
So I think it's better to be atheists...rather than exploring religions randomly...because they won't give you the answers you seek. Also...I think that changing religion every five seconds vilifies people's spirituality.
The problem, in my view, is not that faith isn't a valuable asset in the arsenal of human adaptivity and psychological health, but that Christianity so often fails to have grown up to the moral and intellectual maturity of educated people today.
We all need story and ritual to help us find the meaning in our life. These are tools for connecting our subjective experience of the world with its objective character. Churches, so often, have read the story literally and not, as another poster here has said, as a means toward creating a space in which "true" knowledge can be born and grown. I would say that that true knowledge is of the individual's value and place in a world out of which he/she has arisen and back into which he/she will be returned.
Jesus fought hard to wake up his fellow Jews with teachings and stories which re-awoke their moral turpitude. He didn't really depart from the beliefs of the Jews of his time, only the bureaucratic systematization of those beliefs. I takes but a moment to open your heart and feel again the reason why we have rules and practices and to be open to changing those with the time.
So as the modern child grows up in a world more diverse and more open than the narrow-minded literalists who cling to rules and their consequences would like to consider, it is no wonder that people look in askance at those who should know better.
Today we can contemplate the mystery of our existence better by experiencing science fiction stories than be reading the long ago written stories of the Bible...they take the latest that science has to offer, carve out a space where the potential of humanity has yet to explore, and lead us through some of those possibilities that we need to know about so that we can look into the future and back at the past with a sense that we can come through and make the world and ourselves better than we were before.
As a Christian I find this to be an utter shame but I look to some of our science fiction franchises for glimpses into the mystery of life and our place in it not just for my personal experience of spiritual truth but as examples that today's inspired authors should use to "continue the story" of the relationship between God and His people.
