Following the vote in favour of birth control at the 1930 Lambeth Conference, the Church of England became the first major Christian denomination explicitly to condone the use of birth control. This paper argues that the bishop of Winchester, Theodore Woods, was the previously unheralded principal actor responsible for reversing the position of the Church. Woods was convinced that the Church needed to ‘modernise’ its position in order to secure a receptive audience for its higher-ordered teachings on marriage, sex and especially procreation.
