This essay examines pressures and theological developments regarding sexuality and birth control within Anglicanism, as represented by statements from Lambeth Conferences and in discussions in the Church of England during the early to mid twentieth century, and notes some of the changes in ‘official’ position within US churches and especially The Episcopal Church. It offers comparison with the developments in moral theology within the Roman Catholic Church after 1930 and asks if, and by what means, the two Communions may come to agree on the specific issue of contraception.
