Tiết 1. Thừa Tác Viên Bí Tích Thánh Thể (Điều 900-911)

§1 The only minister who, in the person of Christ, can bring into being the sacrament of the Eucharist, is a validly ordained priest.
§2 Any priest who is not debarred by canon law may lawfully celebrate the Eucharist, provided the provisions of the following canons are observed.

A priest is entitled to offer Mass for anyone, living or dead.

Unless the benefit of Christ’s faithful requires or suggests otherwise, priests may concelebrate the Eucharist; they are, however, fully entitled to celebrate the Eucharist individually, but not while a celebration is taking place in the same church or oratory.

A priest is to be permitted to celebrate the Eucharist, even if he is not known to the rector of the church, provided either that he presents commendatory letters, not more than a year old, from his own Ordinary or Superior, or that it can be prudently judged that he is not debarred from celebrating.

Remembering always that in the mystery of the eucharistic Sacrifice the work of redemption is continually being carried out, priests are to celebrate frequently. Indeed, daily celebration is earnestly recommended, because, even if it should not be possible to have the faithful present, it is an action of Christ and of the Church in which priests fulfil their principal role.

§1 Apart from those cases in which the law allows him to celebrate or concelebrate the Eucharist a number of times on the same day, a priest may not celebrate more than once a day.
§2 If there is a scarcity of priests, the local Ordinary may for a good reason allow priests to celebrate twice in one day or even, if pastoral need requires it, three times on Sundays or holydays of obligation.

A priest may not celebrate the eucharistic Sacrifice without the participation of at least one of the faithful, unless there is a good and reasonable cause for doing so.

In the celebration of the Eucharist, deacons and lay persons are not permitted to say the prayers, especially the eucharistic prayer, nor to perform the actions which are proper to the celebrating priest.

Catholic priests are forbidden to concelebrate the Eucharist with priests or ministers of Churches or ecclesial communities which are not in full communion with the Catholic Church.

A priest is not to omit dutifully to prepare himself by prayer before the celebration of the Eucharist, nor afterwards to omit to make thanksgiving to God.

§1 The ordinary minister of holy communion is a Bishop, a priest or a deacon.
§2 The extraordinary minister of holy communion is an acolyte, or another of Christ’s faithful deputed in accordance with can. 230
§3. [Extraordinary ministers of Holy Communion may not exercise their function if ordinary ministers are present and are not impeded: see Authentic Interpretation of canon 910
§2, 1.VI.1988]

§1 The duty and right to bring the blessed Eucharist to the sick as Viaticum belongs to the parish priest, to assistant priests, to chaplains and, in respect of all who are in the house, to the community Superior in clerical religious institutes or societies of apostolic life.
§2 In a case of necessity, or with the permission at least presumed of the parish priest, chaplain or Superior, who must subsequently be notified, any priest or other minister of holy communion must do this.
