Ven. Pius XII : " It is, therefore, desirable, Venerable Brethren, that all the faithful should be aware that to participate in the eucharistic sacrifice is their chief duty and supreme dignity, and that not in an inert and negligent fashion, giving way to distractions and day-dreaming, but with such earnestness and concentration that they may be united as closely as possible with the High Priest, according to the Apostle, "Let this mind be in you which was also in Christ Jesus."[80] And together with Him and through Him let them make their oblation, and in union with Him let them offer up themselves."

80. It is, therefore, desirable, Venerable Brethren, that all the faithful should be aware that to participate in the eucharistic sacrifice is their chief duty and supreme dignity, and that not in an inert and negligent fashion, giving way to distractions and day-dreaming, but with such earnestness and concentration that they may be united as closely as possible with the High Priest, according to the Apostle, "Let this mind be in you which was also in Christ Jesus."[80] And together with Him and through Him let them make their oblation, and in union with Him let them offer up themselves.

81. It is quite true that Christ is a priest; but He is a priest not for Himself but for us, when in the name of the whole human race He offers our prayers and religious homage to the eternal Father; He is also a victim and for us since He substitutes Himself for sinful man. Now the exhortation of the Apostle, "Let this mind be in you which was also in Christ Jesus," requires that all Christians should possess, as far as is humanly possible, the same dispositions as those which the divine Redeemer had when He offered Himself in sacrifice: that is to say, they should in a humble attitude of mind, pay adoration, honor, praise and thanksgiving to the supreme majesty of God. Moreover, it means that they must assume to some extent the character of a victim, that they deny themselves as the Gospel commands, that freely and of their own accord they do penance and that each detests and satisfies for his sins. It means, in a word, that we must all undergo with Christ a mystical death on the cross so that we can apply to ourselves the words of St. Paul, "With Christ I am nailed to the cross."[81]

82. The fact, however, that the faithful participate in the eucharistic sacrifice does not mean that they also are endowed with priestly power. It is very necessary that you make this quite clear to your flocks.

83. For there are today, Venerable Brethren, those who, approximating to errors long since condemned[82] teach that in the New Testament by the word "priesthood" is meant only that priesthood which applies to all who have been baptized; and hold that the command by which Christ gave power to His apostles at the Last Supper to do what He Himself had done, applies directly to the entire Christian Church, and that thence, and thence only, arises the hierarchical priesthood. Hence they assert that the people are possessed of a true priestly power, while the priest only acts in virtue of an office committed to him by the community. Wherefore, they look on the eucharistic sacrifice as a "concelebration," in the literal meaning of that term, and consider it more fitting that priests should "concelebrate" with the people present than that they should offer the sacrifice privately when the people are absent.

84. It is superfluous to explain how captious errors of this sort completely contradict the truths which we have just stated above, when treating of the place of the priest in the Mystical Body of Jesus Christ. But we deem it necessary to recall that the priest acts for the people only because he represents Jesus Christ, who is Head of all His members and offers Himself in their stead. Hence, he goes to the altar as the minister of Christ, inferior to Christ but superior to the people.[83] The people, on the other hand, since they in no sense represent the divine Redeemer and are not mediator between themselves and God, can in no way possess the sacerdotal power.

85. All this has the certitude of faith. However, it must also be said that the faithful do offer the divine Victim, though in a different sense.

86. This has already been stated in the clearest terms by some of Our predecessors and some Doctors of the Church. "Not only," says Innocent III of immortal memory, "do the priests offer the sacrifice, but also all the faithful: for what the priest does personally by virtue of his ministry, the faithful do collectively by virtue of their intention."[84] We are happy to recall one of St. Robert Bellarmine's many statements on this subject. "The sacrifice," he says "is principally offered in the person of Christ. Thus the oblation that follows the consecration is a sort of attestation that the whole Church consents in the oblation made by Christ, and offers it along with Him."[85]

87. Moreover, the rites and prayers of the eucharistic sacrifice signify and show no less clearly that the oblation of the Victim is made by the priests in company with the people. For not only does the sacred minister, after the oblation of the bread and wine when he turns to the people, say the significant prayer: "Pray brethren, that my sacrifice and yours may be acceptable to God the Father Almighty;"[86] but also the prayers by which the divine Victim is offered to God are generally expressed in the plural number: and in these it is indicated more than once that the people also participate in this august sacrifice inasmuch as they offer the same. The following words, for example, are used: "For whom we offer, or who offer up to Thee . . . We therefore beseech thee, O Lord, to be appeased and to receive this offering of our bounded duty, as also of thy whole household. . . We thy servants, as also thy whole people . . . do offer unto thy most excellent majesty, of thine own gifts bestowed upon us, a pure victim, a holy victim, a spotless victim."[87]

88. Nor is it to be wondered at, that the faithful should be raised to this dignity. By the waters of baptism, as by common right, Christians are made members of the Mystical Body of Christ the Priest, and by the "character" which is imprinted on their souls, they are appointed to give worship to God. Thus they participate, according to their condition, in the priesthood of Christ.

89. In every age of the Church's history, the mind of man, enlightened by faith, has aimed at the greatest possible knowledge of things divine. It is fitting, then, that the Christian people should also desire to know in what sense they are said in the canon of the Mass to offer up the sacrifice. To satisfy such a pious desire, then, We shall here explain the matter briefly and concisely.

90. First of all the more extrinsic explanations are these: it frequently happens that the faithful assisting at Mass join their prayers alternately with those of the priest, and someTimes New Roman - a more frequent occurrence in ancient Times New Roman - they offer to the ministers at the altar bread and wine to be changed into the body and blood of Christ, and, finally, by their alms they get the priest to offer the divine victim for their intentions.

91. But there is also a more profound reason why all Christians, especially those who are present at Mass, are said to offer the sacrifice.

92. In this most important subject it is necessary, in order to avoid giving rise to a dangerous error, that we define the exact meaning of the word "offer." The unbloody immolation at the words of consecration, when Christ is made present upon the altar in the state of a victim, is performed by the priest and by him alone, as the representative of Christ and not as the representative of the faithful. But it is because the priest places the divine victim upon the altar that he offers it to God the Father as an oblation for the glory of the Blessed Trinity and for the good of the whole Church. Now the faithful participate in the oblation, understood in this limited sense, after their own fashion and in a twofold manner, namely, because they not only offer the sacrifice by the hands of the priest, but also, to a certain extent, in union with him. It is by reason of this participation that the offering made by the people is also included in liturgical worship.

93. Now it is clear that the faithful offer the sacrifice by the hands of the priest from the fact that the minister at the altar, in offering a sacrifice in the name of all His members, represents Christ, the Head of the Mystical Body. Hence the whole Church can rightly be said to offer up the victim through Christ. But the conclusion that the people offer the sacrifice with the priest himself is not based on the fact that, being members of the Church no less than the priest himself, they perform a visible liturgical rite; for this is the privilege only of the minister who has been divinely appointed to this office: rather it is based on the fact that the people unite their hearts in praise, impetration, expiation and thanksgiving with prayers or intention of the priest, even of the High Priest himself, so that in the one and same offering of the victim and according to a visible sacerdotal rite, they may be presented to God the Father. It is obviously necessary that the external sacrificial rite should, of its very nature, signify the internal worship of the heart. Now the sacrifice of the New Law signifies that supreme worship by which the principal Offerer himself, who is Christ, and, in union with Him and through Him, all the members of the Mystical Body pay God the honor and reverence that are due to Him.

94. We are very pleased to learn that this teaching, thanks to a more intense study of the liturgy on the part of many, especially in recent years, has been given full recognition. We must, however, deeply deplore certain exaggerations and over-statements which are not in agreement with the true teaching of the Church.

95. Some in fact disapprove altogether of those Masses which are offered privately and without any congregation, on the ground that they are a departure from the ancient way of offering the sacrifice; moreover, there are some who assert that priests cannot offer Mass at different altars at the same time, because, by doing so, they separate the community of the faithful and imperil its unity; while some go so far as to hold that the people must confirm and ratify the sacrifice if it is to have its proper force and value.

96. They are mistaken in appealing in this matter to the social character of the eucharistic sacrifice, for as often as a priest repeats what the divine Redeemer did at the Last Supper, the sacrifice is really completed. Moreover, this sacrifice, necessarily and of its very nature, has always and everywhere the character of a public and social act, inasmuch as he who offers it acts in the name of Christ and of the faithful, whose Head is the divine Redeemer, and he offers it to God for the holy Catholic Church, and for the living and the dead.[88] This is undoubtedly so, whether the faithful are present - as we desire and commend them to be in great numbers and with devotion - or are not present, since it is in no wise required that the people ratify what the sacred minister has done.

97. Still, though it is clear from what We have said that the Mass is offered in the name of Christ and of the Church and that it is not robbed of its social effects though it be celebrated by a priest without a server, nonetheless, on account of the dignity of such an august mystery, it is our earnest desire - as Mother Church has always commanded - that no priest should say Mass unless a server is at hand to answer the prayers, as canon 813 prescribes.
