"At this . . . altar let innocence be in honor, let pride be sacrificed, anger slain, impurity and every evil desire laid low, let the sacrifice of chastity be offered in place of doves and instead of the young pigeons the sacrifice of innocence." While we stand before the altar, then, it is our duty so to transform our hearts, that every trace of sin may be completely blotted out, while whatever promotes supernatural life through Christ may be zealously fostered and strengthened even to the extent that, in union with the immaculate Victim, we become a victim acceptable to the eternal Father."
ENCYCLICAL OF POPE PIUS XII
ON THE SACRED LITURGY
98. In order that the oblation by which the faithful offer the divine Victim in this sacrifice to the heavenly Father may have its full effect, it is necessary that the people add something else, namely, the offering of themselves as a victim.
99. This offering in fact is not confined merely to the liturgical sacrifice. For the Prince of the Apostles wishes us, as living stones built upon Christ, the cornerstone, to be able as "a holy priesthood, to offer up spiritual sacrifices, acceptable to God by Jesus Christ." St. Paul the Apostle addresses the following words of exhortation to Christians, without distinction of time, "I beseech you therefore, . . . that you present your bodies, a living sacrifice, holy, pleasing unto God, your reasonable service." But at that time especially when the faithful take part in the liturgical service with such piety and recollection that it can truly be said of them: "whose faith and devotion is known to Thee," it is then, with the High Priest and through Him they offer themselves as a spiritual sacrifice, that each one's faith ought to become more ready to work through charity, his piety more real and fervent, and each one should consecrate himself to the furthering of the divine glory, desiring to become as like as possible to Christ in His most grievous sufferings.
100. This we are also taught by those exhortations which the Bishop, in the Church's name, addresses to priests on the day of their ordination, "Understand what you do, imitate what you handle, and since you celebrate the mystery of the Lord's death, take good care to mortify your members with their vices and concupiscences." In almost the same manner the sacred books of the liturgy advise Christians who come to Mass to participate in the sacrifice: "At this . . . altar let innocence be in honor, let pride be sacrificed, anger slain, impurity and every evil desire laid low, let the sacrifice of chastity be offered in place of doves and instead of the young pigeons the sacrifice of innocence." While we stand before the altar, then, it is our duty so to transform our hearts, that every trace of sin may be completely blotted out, while whatever promotes supernatural life through Christ may be zealously fostered and strengthened even to the extent that, in union with the immaculate Victim, we become a victim acceptable to the eternal Father.
101. The prescriptions in fact of the sacred liturgy aim, by every means at their disposal, at helping the Church to bring about this most holy purpose in the most suitable manner possible. This is the object not only of readings, homilies and other sermons given by priests, as also the whole cycle of mysteries which are proposed for our commemoration in the course of the year, but it is also the purpose of vestments, of sacred rites and their external splendor. All these things aim at "enhancing the majesty of this great Sacrifice, and raising the minds of the faithful by means of these visible signs of religion and piety, to the contemplation of the sublime truths contained in this sacrifice."
102. All the elements of the liturgy, then, would have us reproduce in our hearts the likeness of the divine Redeemer through the mystery of the cross, according to the words of the Apostle of the Gentiles, "With Christ I am nailed to the cross. I live, now not I, but Christ liveth in me." Thus we become a victim, as it were, along with Christ to increase the glory of the eternal Father.
103. Let this, then, be the intention and aspiration of the faithful, when they offer up the divine Victim in the Mass. For if, as St. Augustine writes, our mystery is enacted on the Lord's table, that is Christ our Lord Himself, who is the Head and symbol of that union through which we are the body of Christ and members of His Body; if St. Robert Bellarmine teaches, according to the mind of the Doctor of Hippo, that in the sacrifice of the altar there is signified the general sacrifice by which the whole Mystical Body of Christ, that is, all the city of redeemed, is offered up to God through Christ, the High Priest: nothing can be conceived more just or fitting than that all of us in union with our Head, who suffered for our sake, should also sacrifice ourselves to the eternal Father. For in the sacrament of the altar, as the same St. Augustine has it, the Church is made to see that in what she offers she herself is offered.
104. Let the faithful, therefore, consider to what a high dignity they are raised by the sacrament of baptism. They should not think it enough to participate in the eucharistic sacrifice with that general intention which befits members of Christ and children of the Church, but let them further, in keeping with the spirit of the sacred liturgy, be most closely united with the High Priest and His earthly minister, at the time the consecration of the divine Victim is enacted, and at that time especially when those solemn words are pronounced, "By Him and with Him and in Him is to Thee, God the Father almighty, in the unity of the Holy Ghost, all honor and glory for ever and ever"; to these words in fact the people answer, "Amen." Nor should Christians forget to offer themselves, their cares, their sorrows, their distress and their necessities in union with their divine Savior upon the cross.
