Pope John Paul II lamented sizable communities who might otherwise have a priest, but don’t. No solutions were forthcoming here, though. Nothing about bishops reassigning clergy from the central see to parishes in need.
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.
The sacramental incompleteness of these celebrations should above all inspire the whole community to pray with greater fervor that the Lord will send laborers into his harvest (cf. Mt 9:38). It should also be an incentive to mobilize all the resources needed for an adequate pastoral promotion of vocations, without yielding to the temptation to seek solutions which lower the moral and formative standards demanded of candidates for the priesthood.
Communities like these–and I have served them–wonder about the motivation for this fervent prayer. Anyone generated in a small parish will move away for training, and be assigned elsewhere.
The comment about the priority for standards is well-taken.
