SACRAMENTUM CARITATIS

Well it's finally out: SACRAMENTUM CARITATIS the Post-Synodal Exhortation on the Eucharist. Not much Earth shaking here, but a wonderful teaching document. While your on the Vatican site take a look at Redemptionis Sacramentum the document from the Congregation for Divine Worship. Combined with the General Instruction of the Roman Missal (GIRM) these documents clearly define how the Liturgy should be said and, just as important, how it should not be said.
If you're a catechist, youth minister or lay minister serving in the liturgy in any capacity you should be familiar with all of these documents.
Things you might not know:

1. While it requires an indult to say the Tridentine Mass, the Mass celebrated in Latin from the pre-Vatican II 1962 Missal, a priest can choose to say the so called Novus Ordo in Latin without getting permission from anyone. As a matter of fact, at international gatherings, except for the scriptural readings, the homily and the prayer of the faithful, which may be said in the vernacular, it is preferred that the Mass be celebrated in Latin. The excepted parts are the same parts that would always be said in English should your parish priest choose to celebrate the Mass in Latin.
2. Active participation is a matter of disposition, not of exterior manifestation. One can be in active participation by being attentive to the liturgy and approaching the Eucharist in the proper state grace.
3. Not all music is appropriate for Liturgy. Conversely liturgical music need not be limited to organ, chant and polyphony. That being said, those three musical forms enjoy a special place in liturgical music and should not be excluded in favor of other styles.
4. Individual reconciliation is preferable to general absolution, which is permitted in only a small number of specific circumstances. Local priests have a duty to make reconciliation available to the faithful.

In this regard, it is important that the confessionals in our churches should be clearly visible expressions of the importance of this sacrament. I ask pastors to be vigilant with regard to the celebration of the sacrament of Reconciliation...
SACRAMENTUM CARITATIS 21.

The entire document is well written and seems to have taken much of its content from the fifty proposals submitted by the Synod of Bishops to the Pope, a clear case of the Magisterium of the Church.
