Regarding episcopal conferences, the document states that "all liturgical norms that a conference of bishops will have established for its territory in accordance with the law are to be submitted to the Congregation for Divine Worship and the Discipline of the Sacraments for the 'recognitio', without which they lack any binding force."
Chapter II is entitled "The Participation of the Lay Christian Faithful in the Eucharistic Celebration" and notes that “the community that gathers for the celebration of the Eucharist absolutely requires an ordained Priest, who presides over it so that it may truly be a eucharistic convocation.
On the question of altar servers, it states that "it is altogether laudable to maintain the noble custom by which boys or youths, customarily termed servers, provide service of the altar after the manner of acolytes, and receive catechesis regarding their function in accordance with their power of comprehension”.
Chapter III, "The Proper Celebration of the Mass," highlights "The Matter of the Most Holy Eucharist" and emphasizes that “the bread used in the celebration of the Most Holy Eucharistic Sacrifice must be unleavened, purely of wheat, and recently made”. Regarding the wine, it states that it “must be natural, from the fruit of the grape, pure and incorrupt, not mixed with other substances." In the same chapter, the instruction says that the proclamation of the Eucharistic Prayer, is proper to the Priest, who must not vary at will the texts of the Sacred Liturgy that they are charged to pronounce.
The instruction states that a homily is given by a priest, occasionally by a concelebrating priest or deacon "but never by a lay person", and also “the priest may give the sign of peace to the ministers but always remains within the sanctuary, so as not to disturb the celebration."
This Chapter concludes that “it is strictly to be considered an abuse to introduce into the celebration of Holy Mass elements that are contrary to the prescriptions of the liturgical books and taken from the rites of other religions."
Chapter IV, "Holy Communion," includes Dispositions for the Reception of Holy Communion. It states that “anyone who is conscious of grave sin should not celebrate or receive the Body of the Lord without prior sacramental confession, except for grave reason when the possibility of confession is lacking; in this case he will remember that he is bound by the obligation of making an act of perfect contrition, which includes the intention to confess as soon as possible."
Concerning the reception of communion, the document notes the right of all the faithful to receive it in the mouth or by hand. In this latter case, it notes that “special care should be taken to ensure that the host is consumed by the communicant in the presence of the minister, so that no one goes away carrying the Eucharistic species in his hand." Also, regarding intinction, "the communicant must not be permitted to intinct the host himself in the chalice, nor to receive the intincted host in the hand."
