A recent edition of The Spectator carried an article by Dan Hitchens in which he quoted the Cambridge historian Richard Rex as saying that there have been three great crises in the history of the Church. The first was over the nature of God (all those fights about Christology in the early Church), the second over the nature of the Church herself (all those Protestant splits during the sixteenth century) and now, a battle over the nature of man (all those fights about what we may or may not do with our bodies).
