Quoting Umberto Eco:
It is the role of religion to provide that justification. Religions are systems of belief that enable human beings to justify their existence and which reconcile us to death. We in Europe have faced a fading of organised religion in recent years. Faith in the Christian churches has been declining.
The ideologies such as communism that promised to supplant religion have failed in spectacular and very public fashion. So we're all still looking for something that will reconcile each of us to the inevitability of our own death.
G K Chesterton is often credited with observing: "When a man ceases to believe in God, he doesn't believe in nothing. He believes in anything." Whoever said it - he was right. We are supposed to live in a sceptical age. In fact, we live in an age of outrageous credulity.
The "death of God", or at least the dying of the Christian God, has been accompanied by the birth of a plethora of new idols. They have multiplied like bacteria on the corpse of the Christian Church -- from strange pagan cults and sects to the silly, sub-Christian superstitions of The Da Vinci Code.
