Jimmy Akin has an update regarding the uses of modified Agnus Dei in the liturgy. He now has the bulletin from the USCCB himself and he posted (bolding is his):
This alteration is effective immediately, and affects all existing and future musical settings of the Lamb of God.
The relevant paragraph [of the bishops' document Sing to the Lord: Music in Divine Worship] now reads (new text in underline):
188. The supplicatory chant Agnus Dei accompanies the Fraction Rite. It is, “asa rule, sung by the choir or cantor with the congregation responding; or it is, at least, recited aloud. This invocation accompanies the fraction and, for this reason, may be repeated as many times as necessary until the rite has reached its conclusion, the last time ending woth the word dona nobis pacem (grant us peace)” (GIRM, no. 83). The Agnus Dei should not be prolonged unnecessarily (see GIRM, no. 83) nor may other texts be added to this chant.
In other liturgical news Rorate Caeli has a letter from the CDW in response to a question from the Philippines.
“The liturgical law of the Roman Rite does not foresee the use of dance or drama within the Sacred Liturgy, unless particular legislation has been enacted by the Bishops’ Conference and confirmed by the Holy See. Any other practice is to be considered an abuse.”
Hey another step to reducing the leotardation of the liturgy.
