Introduction to the Mass
From the General Instruction for the Roman Missal
- The celebration of Mass, as the action of Christ and of the People of God arrayed hierarchically, is the center of the whole of Christian life for the Church both universal and local, as well as for each of the faithful individually. For in it is found the high point both of the action by which God sanctifies the world in Christ and of the worship that the human race offers to the Father, adoring him through Christ, the Son of God, in the Holy Spirit. In it, moreover, during the course of the year, the mysteries of redemption are celebrated so as to be in some way made present. As to the other sacred actions and all the activities of the Christian life, these are bound up with it, flow from it, and are ordered to it.
- It is, therefore, of the greatest importance that the celebration of the Mass or the Lord’s Supper be so ordered that the sacred ministers and the faithful taking part in it, according to the state proper to each, may draw from it more abundantly those fruits, to obtain which, Christ the Lord instituted the Eucharistic Sacrifice of his Body and Blood and entrusted it as the memorial of his Passion and Resurrection to the Church, his beloved Bride.
- This will fittingly come about if, with due regard for the nature and other circumstances of each liturgical assembly, the entire celebration is arranged in such a way that it leads to a conscious, active, and full participation of the faithful, namely in body and in mind, a participation fervent with faith, hope, and charity, of the sort which is desired by the Church and which is required by the very nature of the celebration and to which the Christian people have a right and duty in virtue of their Baptism.
