According to a Vatican source, the commission will approve a proposal and a plan for liturgical reform, which will be made public in the Apostolic Exhortation that the Holy Father will tentatively issue in October.
The Vatican source said that the exhortation would include an invitation to greater use of Latin in the daily prayer of the Church and in the Masswith the exception of the Liturgy of the Wordas well as in large public and international Masses.
The document would also encourage a greater use of Gregorian chant and classical polyphonic music; the gradual elimination of the use of songs whose music or lyrics are secular in origin, as well as the elimination of instruments that are inadequate for liturgical use, such as the electric guitar or drums, although it is not likely that specific instruments will be mentioned.
Lastly, the Pope is expected to call for more decorum and liturgical sobriety in the celebration of the Eucharist, excluding dance and, as much as possible, applause.
