32. All of this shows how distressing and irregular is the situation of a Christian community which, despite having sufficient numbers and variety of faithful to form a parish, does not have a priest to lead it. Parishes are communities of the baptized who express and affirm their identity above all through the celebration of the Eucharistic Sacrifice. But this requires the presence of a presbyter, who alone is qualified to offer the Eucharist in persona Christi. When a community lacks a priest, attempts are rightly made somehow to remedy the situation so that it can continue its Sunday celebrations, and those religious and laity who lead their brothers and sisters in prayer exercise in a praiseworthy way the common priesthood of all the faithful based on the grace of Baptism. But such solutions must be considered merely temporary, while the community awaits a priest.
33. When, due to the scarcity of priests, non-ordained members of the faithful are entrusted with a share in the pastoral care of a parish, they should bear in mind that – as the Second Vatican Council teaches – “no Christian community can be built up unless it has its basis and centre in the celebration of the most Holy Eucharist”.66 They have a responsibility, therefore, to keep alive in the community a genuine “hunger” for the Eucharist, so that no opportunity for the celebration of Mass will ever be missed, also taking advantage of the occasional presence of a priest who is not impeded by Church law from celebrating Mass.
