Catholic philosopher and historian Garry Wills argues that revision, not conservatism, is the historical norm of the Roman Catholic Church.Catholic theological responses to the sexual abuse crisis are split into two main camps: the traditionalist, which claims that a return to pre-Vatican II values will purge the Church of its "modern" problems, and the revisionist, which sees the crisis as symptomatic of deeper institutional ills and calls for further loosening and modernization of canon law. Wills is a leading figure in the latter camp.
