Lumen Gentium: Dogmatic Constitution on the Church

Lumen Gentium, the Dogmatic Constitution on the Church, is one of the principal documents of the Second Vatican Council. This dogmatic constitution was promulgated by Pope Paul VI on 21 November 1964, following approval by the assembled bishops by a vote of 2,151 to 5. As is customary with significant Roman Catholic Church documents, it is known by its first words, "Lumen gentium", Latin for "Light of the Nations".
