Professor McCullough is the General Editor of the new Oxford Edition of the Sermons of John Donne. His lecture will offer some introductory reflections on this new presentation of Donne's greatest prose works, and on the sermons' claims to the attention of both literary scholars and ecclesiastical historians. It will then turn in more detail to Donne's sermons preached at christenings - a body of work long neglected but containing vital evidence of his sacramental theology, and of his responses to Calvinist and Roman Catholic thought.
