With a story set in the fifteenth century featuring oppressed Christians, it is impossible to avoid talking about the Roman Catholic Church. In fact, they were the ones doing the oppressing. In a sense, it would be easy for me to paint the Catholic Church as pure evil—the persecutors of God’s people, the Mary-worshipers, the harlot of Babylon. But Heretics of Piedmont would be very edgy, boring, and frankly, a bad novel if I went down that road.
