Reply to Objection 7: The breaking of the host denotes three things: first, the rending of Christ's body, which took place in the Passion; secondly, the distinction of His mystical body according to its various states; and thirdly, the distribution of the graces which flow from Christ's Passion, as Dionysius observes (Eccl. Hier. iii). Hence this breaking does not imply severance in Christ.
Reply to Objection 8: As Pope Sergius says, and it is to be found in the Decretals (De Consecr., dist. ii), "the Lord's body is threefold; the part offered and put into the chalice signifies Christ's risen body," namely, Christ Himself, and the Blessed Virgin, and the other saints, if there be any, who are already in glory with their bodies. "The part consumed denotes those still walking upon earth," because while living upon earth they are united together by this sacrament; and are bruised by the passions, just as the bread eaten is bruised by the teeth. "The part reserved on the altar till the close of the mass, is His body hidden in the sepulchre, because the bodies of the saints will be in their graves until the end of the world": though their souls are either in purgatory, or in heaven. However, this rite of reserving one part on the altar till the close of the mass is no longer observed, on account of the danger; nevertheless, the same meaning of the parts continues, which some persons have expressed in verse, thus:
"The host being rent---
What is dipped, means the blest;
What is dry, means the living;
What is kept, those at rest."
Others, however, say that the part put into the chalice denotes those still living in this world. while the part kept outside the chalice denotes those fully blessed both in soul and body; while the part consumed means the others.
Reply to Objection 9: Two things can be signified by the chalice: first, the Passion itself, which is represented in this sacrament, and according to this, by the part put into the chalice are denoted those who are still sharers of Christ's sufferings; secondly, the enjoyment of the Blessed can be signified, which is likewise foreshadowed in this sacrament; and therefore those whose bodies are already in full beatitude, are denoted by the part put into the chalice. And it is to be observed that the part put into the chalice ought not to be given to the people to supplement the communion, because Christ gave dipped bread only to Judas the betrayer.
Reply to Objection 10: Wine, by reason of its humidity, is capable of washing, consequently it is received in order to rinse the mouth after receiving this sacrament, lest any particles remain: and this belongs to reverence for the sacrament. Hence (Extra, De Celebratione missae, chap. Ex parte), it is said: "The priest should always cleanse his mouth with wine after receiving the entire sacrament of Eucharist: except when he has to celebrate another mass on the same day, lest from taking the ablution-wine he be prevented from celebrating again"; and it is for the same reason that wine is poured over the fingers with which he had touched the body of Christ.
Reply to Objection 11: The truth ought to be conformable with the figure, in some respect: namely, because a part of the host consecrated, of which the priest and ministers or even the people communicate, ought not to be reserved until the day following. Hence, as is laid down (De Consecr., dist. ii), Pope Clement I ordered that "as many hosts are to be offered on the altar as shall suffice for the people; should any be left over, they are not to be reserved until the morrow, but let the clergy carefully consume them with fear and trembling." Nevertheless, since this sacrament is to be received daily, whereas the Paschal Lamb was not, it is therefore necessary for other hosts to be reserved for the sick. Hence we read in the same distinction: "Let the priest always have the Eucharist ready, so that, when anyone fall sick, he may take Communion to him at once, lest he die without it."
Reply to Objection 12: Several persons ought to be present at the solemn celebration of the mass. Hence Pope Soter says (De Consecr., dist. 1): "It has also been ordained, that no priest is to presume to celebrate solemn mass, unless two others be present answering him, while he himself makes the third; because when he says in the plural, 'The Lord be with you,' and again in the Secrets, 'Pray ye for me,' it is most becoming that they should answer his greeting." Hence it is for the sake of greater solemnity that we find it decreed (De Consecr. dist. 1) that a bishop is to solemnize mass with several assistants. Nevertheless, in private masses it suffices to have one server, who takes the place of the whole Catholic people, on whose behalf he makes answer in the plural to the priest.
Whether the defects occurring during the celebration of this sacrament can be sufficiently met by observing the Church's statutes?
Objection 1: It seems that the defects occurring during the celebration of this sacrament cannot be sufficiently met by observing the statutes of the Church. For it sometimes happens that before or after the consecration the priest dies or goes mad, or is hindered by some other infirmity from receiving the sacrament and completing the mass. Consequently it seems impossible to observe the Church's statute, whereby the priest consecrating must communicate of his own sacrifice.
Objection 2: Further, it sometimes happens that, before the consecration, the priest remembers that he has eaten or drunk something, or that he is in mortal sin, or under excommunication, which he did not remember previously. Therefore, in such a dilemma a man must necessarily commit mortal sin by acting against the Church's statute, whether he receives or not.
Objection 3: Further, it sometimes happens that a fly or a spider, or some other poisonous creature falls into the chalice after the consecration. Or even that the priest comes to know that poison has been put in by some evilly disposed person in order to kill him. Now in this instance, if he takes it, he appears to sin by killing himself, or by tempting God: also in like manner if he does not take it, he sins by acting against the Church's statute. Consequently, he seems to be perplexed, and under necessity of sinning, which is not becoming.
Objection 4: Further, it sometimes happens from the server's want of heed that water is not added to the chalice, or even the wine overlooked, and that the priest discovers this. Therefore he seems to be perplexed likewise in this case, whether he receives the body without the blood, thus making the sacrifice to be incomplete, or whether he receives neither the body nor the blood.
Objection 5: Further, it sometimes happens that the priest cannot remember having said the words of consecration, or other words which are uttered in the celebration of this sacrament. In this case he seems to sin, whether he repeats the words over the same matter, which words possibly he has said before, or whether he uses bread and wine which are not consecrated, as if they were consecrated.
Objection 6: Further, it sometimes comes to pass owing to the cold that the host will slip from the priest's hands into the chalice, either before or after the breaking. In this case then the priest will not be able to comply with the Church's rite, either as to the breaking, or else as to this, that only a third part is put into the chalice.
Objection 7: Further, sometimes, too, it happens, owing to the priest's want of care, that Christ's blood is spilled, or that he vomits the sacrament received, or that the consecrated hosts are kept so long that they become corrupt, or that they are nibbled by mice, or lost in any manner whatsoever; in which cases it does not seem possible for due reverence to be shown towards this sacrament, as the Church's ordinances require. It does not seem then that such defects or dangers can be met by keeping to the Church's statutes.
On the contrary, Just as God does not command an impossibility, so neither does the Church.
I answer that, Dangers or defects happening to this sacrament can be met in two ways: first, by preventing any such mishaps from occurring: secondly, by dealing with them in such a way, that what may have happened amiss is put right, either by employing a remedy, or at least by repentance on his part who has acted negligently regarding this sacrament.
Reply to Objection 1: If the priest be stricken by death or grave sickness before the consecration of our Lord's body and blood, there is no need for it to be completed by another. But if this happens after the consecration is begun, for instance, when the body has been consecrated and before the consecration of the blood, or even after both have been consecrated, then the celebration of the mass ought to be finished by someone else. Hence, as is laid down (Decretal vii, q. 1), we read the following decree of the (Seventh) Council of Toledo: "We consider it to be fitting that when the sacred mysteries are consecrated by priests during the time of mass, if any sickness supervenes, in consequence of which they cannot finish the mystery begun, let it be free for the bishop or another priest to finish the consecration of the office thus begun. For nothing else is suitable for completing the mysteries commenced, unless the consecration be completed either by the priest who began it, or by the one who follows him: because they cannot be completed except they be performed in perfect order. For since we are all one in Christ, the change of persons makes no difference, since unity of faith insures the happy issue of the mystery. Yet let not the course we propose for cases of natural debility, be presumptuously abused: and let no minister or priest presume ever to leave the Divine offices unfinished, unless he be absolutely prevented from continuing. If anyone shall have rashly presumed to do so, he will incur sentence of excommunication."
Reply to Objection 2: Where difficulty arises, the less dangerous course should always be followed. But the greatest danger regarding this sacrament lies in whatever may prevent its completion, because this is a heinous sacrilege; while that danger is of less account which regards the condition of the receiver. Consequently, if after the consecration has been begun the priest remembers that he has eaten or drunk anything, he ought nevertheless to complete the sacrifice and receive the sacrament. Likewise, if he recalls a sin committed, he ought to make an act of contrition, with the firm purpose of confessing and making satisfaction for it: and thus he will not receive the sacrament unworthily, but with profit. The same applies if he calls to mind that he is under some excommunication; for he ought to make the resolution of humbly seeking absolution; and so he will receive absolution from the invisible High Priest Jesus Christ for his act of completing the Divine mysteries.
But if he calls to mind any of the above facts previous to the consecration, I should deem it safer for him to interrupt the mass begun, especially if he has broken his fast, or is under excommunication, unless grave scandal were to be feared.
Reply to Objection 3: If a fly or a spider falls into the chalice before consecration, or if it be discovered that the wine is poisoned, it ought to be poured out, and after purifying the chalice, fresh wine should be served for consecration. But if anything of the sort happen after the consecration, the insect should be caught carefully and washed thoroughly, then burned, and the "ablution," together with the ashes, thrown into the sacrarium. If it be discovered that the wine has been poisoned, the priest should neither receive it nor administer it to others on any account, lest the life-giving chalice become one of death, but it ought to be kept in a suitable vessel with the relics: and in order that the sacrament may not remain incomplete, he ought to put other wine into the chalice, resume the mass from the consecration of the blood, and complete the sacrifice.
