The constitution on the Sacred Liturgy Sacrosanctum Concilium was solemnly promulgated by His Holiness Pope Paul VI on 4 December 1963. It is surprisingly full of good things. “The use of the Latin language is to be preserved in the Latin rites” (Article 36.1); “The Church acknowledges Gregorian chant as specially suited to the Roman liturgy; therefore other things being equal, it should be given pride of place in liturgical services” (Article 115); “Ordinaries must be very careful to see that sacred furnishings and works of value are not disposed of or dispersed; for they are the ornaments of the house of God.”(Article 126).
