First, Notre-Dame is, in many ways, one of the key repositories of Western Civilization (which is largely CHRISTIAN civilization). It not only held great works of art, but it was, even for the most secular, a significant cultural element. But perhaps the most important reason it matters--besides it's meaning to Christianity, per se--is simply that IT MATTERS TO THE PEOPLE OF EARTH.Yes, it took a great burning to cause an increasingly secularized world to turn teary eyes toward that great cathedral and realize just how much it meant to them. It is perhaps something like a once-beloved great-uncle who received few calls and visits, but upon nearing death, his relatives realize just how much they will lose by losing him.Something similar happened on 9/11, I think, though it was more dramatic, especially in terms of deaths. It might be that this would be a wondrous opportunity for believers to reach out to secularized, non-religious Frenchmen and call them back to what, in their souls, they now see as something that is priceless.One day, if the Lord tarries, the last church may be closed or burn to the ground. It might be only then that people realize that the sweet Voice that was calling to them, wooing them, has gone silent.
