THE MINISTER OF THE MOST HOLY EUCHARIST
Can. 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.
Can. 901 A priest is free to apply the Mass for anyone, living or dead.
Can. 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.
Can. 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.
Can. 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.
Can. 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.

Can. 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.
Can. 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.
Can. 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.
Can. 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.
Can. 910 §1. The ordinary minister of holy communion is a bishop, presbyter, or deacon.
§2. The extraordinary minister of holy communion is an acolyte or another member of the Christian faithful designated according to the norm of ⇒ can. 230, §3.
Can. 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
