CHAPTER I : THE CELEBRATION OF THE EUCHARIST

Can. 899 §1 The celebration of the Eucharist is an action of Christ himself and of the Church. In it Christ the Lord, through the ministry of the priest, offers himself, substantially present under the appearances of bread and wine, to God the Father, and gives himself as spiritual nourishment to the faithful who are associated with him in his offering.

§2 In the eucharistic assembly the people of God are called together under the presidency of the Bishop or of a priest authorised by him, who acts in the person of Christ. All the faithful present, whether clerics or lay people, unite to participate in their own way, according to their various orders and liturgical roles.

§3 The eucharistic celebration is to be so ordered that all the participants derive from it the many fruits for which Christ the Lord instituted the eucharistic Sacrifice.
