Lumen Gentium, the Dogmatic Constitution on the Church, is one of the principal documents of the Second Vatican Council. The Constitution was promulgated by Pope Paul VI on November 21, 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".
