The fourth reason for reservation is in order that the faithful may receive Communion on a Sunday or other Holy Day in the absence of the
priest in the frame of an appropriate service, a need that emerged with the fall in the number of
vocations.
Catholic Church In the
Catholic Church, the main document that rules this celebration is the
Directory for Sunday Celebrations in the Absence of a Priest issued by the
Congregation for Divine Worship and the Discipline of the Sacraments on June 2, 1988. This celebration is never called
Mass, because it lacks the consecration of the
Eucharist. When it is possible this celebration is led by a
deacon (who wears his own vestment), otherwise it is led by an appointed layperson, who acts as one among equals, in the way followed in the
Liturgy of the Hours when not presided over by an ordained minister and who sits outside the sanctuary. The structure of the celebration is the following: • Introductory rites: similar in aim and structure to the
Introductory rites of the Mass, though the greeting, "The Lord be with you" is reserved to the priest or deacon; another format is used when a layperson presides at the service (the word "celebrant" should only be used for an ordained priest when he is officiating at Mass); • Liturgy of the Word: similar in aim and structure to the
Liturgy of the Word of the Mass. The readings are the same as in the Mass of the day. The
homily can be given only by the deacon, if present, otherwise the layperson might read a homily previously prepared by a priest; • Thanksgiving: a
hymn,
psalm, or
litany in which the faithful praise the glory and mercy of God. It shall not to be similar to the thanksgiving of the
Eucharistic prayers. • Communion rites: the ritual of the
Roman Ritual for
Communion outside Mass shall be used. For Communion, if at all possible, hosts consecrated that same Sunday in a Mass celebrated elsewhere is used, otherwise the reserved hosts are used; • Concluding rites: similar in aim and structure to the ones in the Mass. The
Directory for Sunday Celebrations in the Absence of a Priest remarks many times the need to use prayers, wordings, and gestures different from those used in the Mass, in order to avoid confusion.
Lutheran Churches In the
Lutheran view, the sacraments belong to the entirety of the Church, rather than to an institutional hierarchy. As such in rare cases, lay celebrations of the Eucharist are authorized when no priest is available:
Anglican Communion In the
Anglican Communion a similar problem has resulted in the
General Synod of the
Church of England authorising a service of Communion by Extension. Because of the traditional hostility to reservation, apart from the requirement that the Communion continues to be celebrated 'regularly' in each parish church, the instruction is that "the consecrated bread and wine be brought to the church from the celebration of Holy Communion in a seemly and dignified manner" implying that the service will have taken place in another church but on the same day. Moreover, "[e]xplicit permission must be obtained from the bishop for the use of this rite. This permission should relate to specific pastoral circumstances, thus emphasizing the exceptional nature of this ministry." ==Eastern Christian==
