By Anthony Esolen, The Catholic Thing - Pope Francis recently said, in one of his disquieting comments that sound contemptuous for the Church he is charged to love, that her teachings on sex are “still in diapers.” My mind turns to Christian poets who have written about the love of man and woman, and the moral dangers that beset it, from the troubadours and the Arthurian romancers of the twelfth century, to such modern Catholic authors as Mauriac, Claudel, Greene, Waugh, Böll, Percy, and Francis’ own predecessor, John Paul II.
