Yesterday my wife and daughter and I visited Chartres Cathedral, just outside of Paris. The Cathedral is perhaps the world’s greatest surviving example of medieval Gothic architecture, primarily because it remains much the way it was in the 13th century, including having the original stained glass windows, which are nothing short of stunning!
These amazing works of art (and indeed, the Cathedral itself is a masterpiece), incredibly survived not only the French Revolution but WWII as well, despite all odds. The story of how the Cathedral survived WWII is especially fascinating.
When Allied Forces decided to bomb the cathedral on the suspicion that it might be occupied by German troops, an American colonel by the name of Welborn Griffith challenged the order, and volunteered instead to cross the front lines and investigate to see if Germans were actually holed up in the church. His request was approved, and after making his way to the cathedral, he discovered indeed that there were no Germans. As a result, Chartres Cathedral was saved from total destruction. Unfortunately, Griffith was killed a few days later in the fighting to liberate the town of Chartres.
Commonly, parallels are drawn between the great churches of Europe and the decline of Christianity there, and the general tendency is to criticize Catholicism for having built enduring buildings but no lasting churches.
Our trip to Chartres though had a different effect on me. Instead, what I saw in this magnificent Cathedral is rather a symbol of the survivability of the Church. God, working through frail and imperfect human agents, like Colonel Griffith, will ensure the survival of His Church. After all, He promised as much when He said the gates of hell shall not prevail against it (Matt. 16:18).
And so as we walked around Chartres, taking in its incredible beauty and history, I found myself reminded that the Church will survive the moral decline of western cultures and the propensity of men for war. It will survive terrorism and it will survive revolutions. And most incredibly, it will even survive the theological differences among its members.
