Chapter 2 (The Mass): the Eucharist is both the sacrifice of Christ's body and blood and a paschal banquet. In addition to repeating the need for simplification of the rites and active participation, the chapter decrees that certain practices that had disappeared (such as the prayer of the faithful, concelebration, and communion under both kinds for the laity) are to be restored under certain conditions, and that the homily should be a commentary on the Scripture readings. Chapter 3 (Sacraments): the rite of each sacrament is to be simplified in order to make its meaning clear; the catechumenate is to be restored for adult baptism; the link between confirmation and baptism is to be made clear; the sacrament then called extreme unction is to become a sacrament for those who are seriously ill (anointing of the sick) and not just of those who are on the point of death; funerals are to focus on the hope of the resurrection and not on mourning, and local cultural practices may be included in the celebration of some sacraments such as weddings.
