“How does an angel get it wrong?” Rev. John D. Corbett asked during his lecture to students and faculty on January 27 at Christendom College. Rev. Corbett’s talk, entitled “The Angelic Doctor and the Lord of the Angels,” was the annual St. Thomas Aquinas Lecture, which discussed the nature of angels and how such high beings could have fallen from God’s grace. A moral theologian currently teaching at the Pontifical Faculty of the Immaculate Conception, Rev. Corbett explained that the fall of the angels is “a bit of a theological conundrum.”
