Canon 899. §1. The eucharistic celebration is the action of Christ himself and the Church. In it, Christ the Lord, through the ministry of the priest, offers himself, substantially present under the species of bread and wine, to God the Father and gives himself as spiritual food to the faithful united with his offering.
§2. In the eucharistic gathering the people of God are called together with the bishop or, under his authority, a presbyter presiding and acting in the person of Christ. All the faithful who are present, whether clerics or laity, unite together by participating in their own way according to the diversity of orders and liturgical functions.
§3. The eucharistic celebration is to be organized in such a way that all those participating receive from it the many fruits for which Christ the Lord instituted the eucharistic sacrifice.
Canon 900. §1. The minister who is able to confect the sacrament of the Eucharist in the person of Christ is a validly ordained priest alone.
§2. A priest not impeded by canon law celebrates the Eucharist licitly; the provisions of the following canons are to be observed.
Canon 901. A priest is free to apply the Mass for anyone, living or dead.
Canon 902. Unless the welfare of the Christian faithful requires or suggests otherwise, priests can concelebrate the Eucharist. They are completely free to celebrate the Eucharist individually, however, but not while a concelebration is taking place in the same church or oratory.
Canon 903. A priest is to be permitted to celebrate even if the rector of the church does not know him, provided that either he presents a letter of introduction from his ordinary or superior, issued at least within the year, or it can be judged prudently that he is not impeded from celebrating.
Canon 904. Remembering always that in the mystery of the eucharistic sacrifice the work of redemption is exercised continually, priests are to celebrate frequently; indeed, daily celebration is recommended earnestly since, even if the faithful cannot be present, it is the act of Christ and the Church in which priests fulfill their principal function.
Canon 905. §1. A priest is not permitted to celebrate the Eucharist more than once a day except in cases where the law permits him to celebrate or concelebrate more than once on the same day.
§2. If there is a shortage of priests, the local ordinary can allow priests to celebrate twice a day for a just cause, or if pastoral necessity requires it, even three times on Sundays and holy days of obligation.
Canon 906. Except for a just and reasonable cause, a priest is not to celebrate the eucharistic sacrifice without the participation of at least some member of the faithful.
Canon 907. In the eucharistic celebration deacons and lay persons are not permitted to offer prayers, especially the eucharistic prayer, or to perform actions which are proper to the celebrating priest.
Canon 908. Catholic priests are forbidden to concelebrate the Eucharist with priests or ministers of Churches or ecclesial communities which do not have full communion with the Catholic Church.
Canon 909. A priest is not to neglect to prepare himself properly through prayer for the celebration of the eucharistic sacrifice and to offer thanks to God at its completion.

Canon 911. §1. The pastor, parochial vicars, chaplains, and, with regard to all those dwelling in the house, the superior of a community in clerical religious institutes and societies of apostolic life have the duty and right of bringing the Most Holy Eucharist as Viaticum to the sick.
§2. In the case of necessity or with at least the presumed permission of the pastor, chaplain, or superior, who must be notified afterwards, any priest or other minister of holy communion must do this.
Canon 912. Any baptized person not prohibited by law can and must be admitted to holy communion.
Canon 913. §1. The administration of the Most Holy Eucharist to children requires that they have sufficient knowledge and careful preparation so that they understand the mystery of Christ according to their capacity and are able to receive the body of Christ with faith and devotion.
Canon 914. It is primarily the duty of parents and those who take the place of parents, as well as the duty of pastors, to take care that children who have reached the use of reason are prepared properly and, after they have made sacramental confession, are refreshed with this divine food as soon as possible. It is for the pastor to exercise vigilance so that children who have not attained the use of reason or whom he judges are not sufficiently disposed do not approach holy communion.
Canon 915. Those who have been excommunicated or interdicted after the imposition or declaration of the penalty and others obstinately persevering in manifest grave sin are not to be admitted to holy communion.
Canon 916. A person who is conscious of grave sin is not to celebrate Mass or receive the body of the Lord without previous sacramental confession unless there is a grave reason and there is no opportunity to confess; in this case the person is to remember the obligation to make an act of perfect contrition which includes the resolution of confessing as soon as possible.
Canon 917. A person who has already received the Most Holy Eucharist can receive it a second time on the same day only within the eucharistic celebration in which the person participates, without prejudice to the prescript of can. 921, §2.
Canon 918. It is highly recommended that the faithful receive holy communion during the eucharistic celebration itself. It is to be administered outside the Mass, however, to those who request it for a just cause, with the liturgical rites being observed.
Canon 919. §1. A person who is to receive the Most Holy Eucharist is to abstain for at least one hour before holy communion from any food and drink, except for only water and medicine.
