Haha, this atheist got 30 out of 32 too. And one of them was the one about transubstantiation, which I feel dumb I missed; I was raised orthodox and always get mixed up about who thinks transubstantiation is literal and who thinks it's symbolic. I feel like most people who are missing that question aren't missing it because they can't remember whether Rome & Constantinople split over that in addition to all their other disagreements :D
