The role of celibacy differs cross-culturally among religious traditions, with some insisting on it and others prohibiting it. Obligatory celibacy for Catholic priests in the West was introduced in 1130, yet in other traditions, such as Islam, marriage for their spiritual leaders is positively encouraged and celibacy, whilst not forbidden, is seen as second class. Is celibacy an essential requirement for real closeness to God or not? And given that it's basis is essentially cultural rather than theological, should celibacy be optional across religions?

Joining Ernie Rea to discuss celibacy across religions are Professor Carl Olsen, Prof of Religious Studies at Allegheny College, Pennsylvania, and Editor of the book, Celibacy and Religious Traditions; Dr Helen Costigane SHCJ, member of the Society of the Holy Child Jesus, who teaches Canon Law and Christian Ethics at Heythrop College, University of London, and Sheikh Michael Mumisa, Islamic scholar at the University of Cambridge.
