There always seems to be a bit of confusion around this week’s Solemnity. Despite falling in the middle of Advent, December 8 is not a celebration of the conception of Jesus—which would have meant a remarkably brief pregnancy—but of Mary.
Still, even if we remember whose life it is we’re celebrating, that doesn’t clear up every mystery about the Immaculate Conception. I must confess that for most of my life even though I knew we had to go to church on December 8, I wasn’t exactly sure why. It had something to do with one of those Marian dogmas, I knew, but most Catholics tiptoe around those nowadays for fear of offending the Protestants. And even though I, being a somewhat contrarian lad, was prepared to pick Mary over the Protestants, I really had no idea why.
Even today, while I know a bit more about theology, I still have to admit to finding this particular Mystery particularly mysterious. Among the writing I’ve found shedding light on the subject is an excellent essay titled “The Immaculate Conception” by the British Thomist, Herbert McCabe, OP.
