The basic premise of the Tolkien/supernatural mini cor is to reintroduce into the hearts of secular society the idea that the supernatural is not contradictory to philosophy or logic: it's about the reality of Jesus who loves us. Yes, John Harvard was Oxford educated, but so was Tolkien, and he was a daily communicant who called the Eucharist his greatest love. So as Peter Kreeft would recommend, put Tolkien in dialogue with the "debater of this age."
