Casti connubii (Latin: "of chaste wedlock")[1] is a papal encyclical promulgated by Pope Pius XI on 31 December 1930 in response to the Lambeth Conference of the Anglican Communion. It stressed the sanctity of marriage, prohibited Catholics from using any form of artificial birth control, and reaffirmed the prohibition on abortion. It also explained the authority of church doctrine on moral matters, and advocated that civil governments follow the lead of the church in this area.
