Sacrosanctum Concilium

Fr. Gonzales has a good list of parts of the Vatican II document, Sacrosanctum Concilium, that modernists and liberals need to read:

2. In virtue of power conceded by the law, the regulation of the liturgy within certain defined limits belongs also to various kinds of competent territorial bodies of bishops legitimately established....3. Therefore, no other person, even if he be a priest, may add, remove, or change anything in the liturgy on his own authority.

36.1. Particular law remaining in force, the use of the Latin language is to be preserved in the Latin rites.

54....steps should be taken so that the faithful may also be able to say or to sing together in Latin those parts of the Ordinary of the Mass which pertain to them.

115....Composers and singers, especially boys, must also be given a genuine liturgical training.

116. 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.

120. In the Latin Church the pipe organ is to be held in high esteem, for it is the traditional musical instrument which adds a wonderful splendor to the Church's ceremonies and powerfully lifts up man's mind to God and to higher things.

121. The texts intended to be sung must always be in conformity with Catholic doctrine; indeed they should be drawn chiefly from Holy Scripture and from liturgical sources.

124....Let bishops carefully remove from the house of God and from other sacred places those works of artists which are repugnant to faith, morals, and Christian piety, and which offend true religious sense either by depraved forms or by lack of artistic worth, mediocrity and pretense.
