Sarah Dunant sees a new crisis in the Catholic church as a result of unchanged policy over divorce, homosexuality, celibacy and the role of women.

"Men may truly believe in God but for most of them chastity is too big an ask and if enforced leads, at worst, to abuse and at best to a clergy and hierarchy ignorant of, and often unsympathetic to, the problems of being human. From there it's but a skip and a jump to the role of women and their exclusion from the heart of the church."
