20 (Providing equitable remuneration for priests.) As those dedicated to the service of God and the fulfillment of the office entrusted to them, priests deserve to receive an equitable remuneration, because "the laborer is worthy of his hire," (Lk 10:7) and "the Lord directed that those who preach the Gospel should have their living from the Gospel" (1 Cor 9:14). Wherefore, insofar as an equitable remuneration of the priests would not be provided otherwise, the faithful themselves-that is, those in whose behalf the priest labors-are truly obliged to see to it that they can provide what help is necessary for the honorable and worthy life of the priests. The bishops, however, should admonish the faithful concerning this obligation of theirs. And they should see to if whether each individual for his own diocese or, more aptly, several together for their common territory-that norms are established according to which suitable support is rightly provided for those who do fulfill or have fulfilled a special office in the service of the People of God. The remuneration received by each one, in accord with his office and the conditions of time and place, should be fundamentally the same for all in the same circumstances and befitting his station. Moreover, those who have dedicated themselves to the service of the priesthood, by reason of the remuneration they receive, should not only be able to honorably provide for themselves but also themselves be provided with some means of helping the needy. For the ministry to the poor has always been held in great honor in the Church from its beginnings. Furthermore, this remuneration should be such that it will permit priests each year to take a suitable and sufficient vacation, something which indeed the bishops should see that their priests are able to have. Special importance ought to be given to the office fulfilled by sacred ministers. Therefore the so-called system of benefices should be relinquished or at least so reformed that the place of the benefits, or the right to revenue from the endowment attached to an office, would be held as secondary, and the first place in law would be given to the ecclesiastical office itself. From this it should be understood that whatever office is conferred in a stable manner is to be exercised for a spiritual purpose.
