The Keystone at Chartres

Marie-Claire was seven years old the first time her grandfather took her inside Chartres Cathedral. She remembers tilting her head back until her neck ached, staring up into the ribbed vaults soaring a hundred and twenty feet above the nave floor. "How does it stay up?" she whispered. Her grandfather, a retired stonemason, knelt beside her and pointed to the center of the nearest arch. "You see that stone at the very top? That is the keystone. Every other stone in the arch pushes against it. Take it away, and the whole ceiling falls. Leave it in place, and all that weight becomes strength."

Decades later, Marie-Claire would tell her own grandchildren that she never read Colossians 1:15-17 the same way again. Paul declares that Christ is the image of the invisible God — the One in whom all things were created and in whom all things hold together. Every molecule, every galaxy, every human heartbeat presses against Him the way those limestone blocks press against the keystone at Chartres. He does not merely decorate the structure. He bears the full weight of it. Remove Him, and creation has no center, no coherence, no reason to stand. But because He is before all things — before the first star burned, before the first breath was drawn — the whole universe finds its shape and its strength in Him alone.
