It must have been in the spring of 2018, because that was the last time I was in Paris. I had been invited to give a talk; my hotel was near the Church of Saint-Sulpice, which I had never visited before. And in that immense cathedral my heart began to pound, because walking beneath those vaulted ceilings, and past the candles, and still-life scenes of mortification, and other citizens waiting to take communion in what felt like the most public way possible, I felt what I was meant to feel in that eighteenth-century edifice: the smallness of man, and the large invincibility of God.
