Jennifer Smith is Associate Professor of English, Coordinator of Digital Humanities, and Associate Director of the Center for Faith and Learning at Pepperdine University. She is a noted medievalist, and also a 2022-2023 sabbatical fellow at the Benson Center. We discuss the life and legacy of the fifteenth-century English bishop Reginald Peacock, who was defrocked and exiled for heresy-i.e. canceled-for questioning the infallibility of the church and advocating the authority of reason.
