While Vatican II marked a great change in the Church, it also emphasized tradition and continuity. Here are some precepts of the great council that are often overlooked.
From “The Constitution on the Sacred Liturgy” Sacrosanctum Concilium, 4 December, 1963.
Article 36. (1) The use of the Latin language, with due respect to particular law, is to be preserved in the Latin rites. (2) But since the use of the vernacular, whether in the Mass, the administration of the sacraments, or in other parts of the liturgy, may frequently be of great advantage to the people, a wider use may be made of it, especially in readings, directives and in some prayers and chants. Regulations governing this will be given separately in subsequent chapters. (emphasis added)
Article 112. The musical tradition of the universal Church is a treasure of inestimable value, greater even than that of any other art. The main reason for this pre-eminence is that, as a combination of sacred music and words, it forms a necessary or integral part of the solemn liturgy.
Article 116. The Church recognizes Gregorian chant as being specially suited to the Roman liturgy. Therefore, other things being equal, it should be given pride of place in liturgical services.
Article 120. The pipe organ is to be held in high esteem in the Latin Church, for it is the traditional musical instrument, the sound of which can add a wonderful splendor to the Church’s ceremonies and powerfully lifts up men’s minds to God and higher things.
