Sacrosanctum Concilium

Sacrosanctum Concilium, the Constitution on the Sacred Liturgy, is one of the constitutions of the Second Vatican Council. It was approved by the assembled bishops by a vote of 2,147 to 4 and promulgated by Pope Paul VI on 4 December 1963.[1] The main aim was to revise the traditional liturgical texts and rituals to reflect more fully fundamental principles, and be more pastorally effective in the changed conditions of the times, clarifying not only the role of ordained ministers but the modalities of appropriate participation of lay faithful in the Catholic Church's liturgy, especially that of the Roman Rite. The title is taken from the opening lines of the document and means "this Sacred Council".
