Summa Th. III EN Qu.80 a.7

Whether the seminal loss that occurs during sleep hinders anyone from receiving this sacrament?



Objection: 1. It seems that seminal loss does not hinder anyone from receiving the body of Christ: because no one is prevented from receiving the body of Christ except on account of sin. But seminal loss happens without sin: for Augustine says (Gn ad lit. xii) that "the same image that comes into the mind of a speaker may present itself to the mind of the sleeper, so that the latter be unable to distinguish the image from the reality, and is moved carnally and with the result that usually follows such motions; and there is as little sin in this as there is in speaking and therefore thinking about such things." Consequently these motions do not prevent one from receiving this sacrament.
2. Further, Gregory says in a Letter to Augustine, Bishop of the English (Regist. xi): "Those who pay the debt of marriage not from lust, but from desire to have children, should be left to their own judgment, as to whether they should enter the church and receive the mystery of our Lord's body, after such intercourse: because they ought not to be forbidden from receiving it, since they have passed through the fire unscorched."From this it is evident that seminal loss even of one awake, if it be without sin, is no hindrance to receiving the body of Christ. Consequently, much less is it in the case of one asleep.
3. Further, these movements of the flesh seem to bring with them only bodily uncleanness. But there are other bodily defilements which according to the Law forbade entrance into the holy places, yet which under the New Law do not prevent receiving this sacrament: as, for instance, in the case of a woman after child-birth, or in her periods, or suffering from issue of blood, as Gregory writes to Augustine, Bishop of the English (Regist. xi). Therefore it seems that neither do these movements of the flesh hinder a man from receiving this sacrament.
4. Further, venial sin is no hindrance to receiving the sacrament, nor is mortal sin after repentance. But even supposing that seminal loss arises from some foregoing sin, whether of intemperance, or of bad thoughts, for the most part such sin is venial; and if occasionally it be mortal, a man may repent of it by morning and confess it. Consequently, it seems that he ought not to be prevented from receiving this sacrament.
5. Further, a sin against the Fifth Commandment is greater than a sin against the Sixth. But if a man dream that he has broken the Fifth or Seventh or any other Commandment, he is not on that account debarred from receiving this sacrament. Therefore it seems that much less should he be debarred through defilement resulting from a dream against the Sixth Commandment.

On the contrary It is written (Lv 15,16): "The man from whom the seed of copulation goeth out . . . shall be unclean until evening." But for the unclean there is no approaching to the sacraments. Therefore, it seems that owing to such defilement of the flesh a man is debarred from taking this which is the greatest of the sacraments.
I answer that There are two things to be weighed regarding the aforesaid movements: one on account of which they necessarily prevent a man from receiving this sacrament; the other, on account of which they do so, not of necessity, but from a sense of propriety.Mortal sin alone necessarily prevents anyone from partaking of this sacrament: and although these movements during sleep, considered in themselves, cannot be a mortal sin, nevertheless, owing to their cause, they have mortal sin connected with them; which cause, therefore, must be investigated. Sometimes they are due to an external spiritual cause, viz. the deception of the demons, who can stir up phantasms, as was stated in the I 111,3, through the apparition of which, these movements occasionally follow. Sometimes they are due to an internal spiritual cause, such as previous thoughts. At other times they arise from some internal corporeal cause, as from abundance or weakness of nature, or even from surfeit of meat or drink. Now every one of these three causes can be without sin at all, or else with venial sin, or with mortal sin. If it be without sin, or with venial sin, it does not necessarily prevent the receiving of this sacrament, so as to make a man guilty of the body and blood of the Lord: but should it be with mortal sin, it prevents it of necessity.For such illusions on the part of demons sometimes come from one's not striving to receive fervently; and this can be either a mortal or a venial sin. At other times it is due to malice alone on the part of the demons who wish to keep men from receiving this sacrament. So we read in the Conferences of the Fathers (Cassian, Collat. xxii) that when a certain one always suffered thus on those feast-days on which he had to receive Communion, his superiors, discovering that there was no fault on his part, ruled that he was not to refrain from communicating on that account, and the demoniacal illusion ceased.In like fashion previous evil thoughts can sometimes be without any sin whatever, as when one has to think of such things on account of lecturing or debating; and if it be done without concupiscence and delectation, the thoughts will not be unclean but honest; and yet defilement can come of such thoughts, as is clear from the authority of Augustine (Objection [1]). At other times such thoughts come of concupiscence and delectation, and should there be consent, it will be a mortal sin: otherwise it will be a venial sin.In the same way too the corporeal cause can be without sin, as when it arises from bodily debility, and hence some individuals suffer seminal loss without sin even in their wakeful hours; or it can come from the abundance of nature: for, just as blood can flow without sin, so also can the semen which is superfluity of the blood, according to the Philosopher (De Gener. Animal. i). But occasionally it is with sin, as when it is due to excess of food or drink. And this also can be either venial or mortal sin; although more frequently the sin is mortal in the case of evil thoughts on account of the proneness to consent, rather than in the case of consumption of food and drink. Hence Gregory, writing to Augustine, Bishop of the English (Regist. xi), says that one ought to refrain from Communion when this arises from evil thoughts, but not when it arises from excess of food or drink, especially if necessity call for Communion. So, then, one must judge from its cause whether such bodily defilement of necessity hinders the receiving of this sacrament.At the same time a sense of decency forbids Communion on two accounts. The first of these is always verified, viz. the bodily defilement, with which, out of reverence for the sacrament, it is unbecoming to approach the altar (and hence those who wish to touch any sacred object, wash their hands): except perchance such uncleanness be perpetual or of long standing, such as leprosy or issue of blood, or anything else of the kind. The other reason is the mental distraction which follows after the aforesaid movements, especially when they take place with unclean imaginings. Now this obstacle, which arises from a sense of decency, can be set aside owing to any necessity, as Gregory says (Regist. xi): "As when perchance either a festival day calls for it, or necessity compels one to exercise the ministry because there is no other priest at hand."

Reply to Objection: 1. A person is hindered necessarily, only by mortal sin, from receiving this sacrament: but from a sense of decency one may be hindered through other causes, as stated above.
2. Conjugal intercourse, if it be without sin, (for instance, if it be done for the sake of begetting offspring, or of paying the marriage debt), does not prevent the receiving of this sacrament for any other reason than do those movements in question which happen without sin, as stated above; namely, on account of the defilement to the body and distraction to the mind. On this account Jerome expresses himself in the following terms in his commentary on Matthew (Epist. xxviii, among St. Jerome's works): "If the loaves of Proposition might not be eaten by them who had known their wives carnally, how much less may this bread which has come down from heaven be defiled and touched by them who shortly before have been in conjugal embraces? It is not that we condemn marriages, but that at the time when we are going to eat the flesh of the Lamb, we ought not to indulge in carnal acts." But since this is to be understood in the sense of decency, and not of necessity, Gregory says that such a person "is to be left to his own judgment." "But if," as Gregory says (Regist. xi), "it be not desire of begetting offspring, but lust that prevails," then such a one should be forbidden to approach this sacrament.
3. As Gregory says in his Letter quoted above to Augustine, Bishop of the English, in the Old Testament some persons were termed polluted figuratively, which the people of the New Law understand spiritually. Hence such bodily uncleannesses, if perpetual or of long standing, do not hinder the receiving of this saving sacrament, as they prevented approaching those figurative sacraments; but if they pass speedily, like the uncleanness of the aforesaid movements, then from a sense of fittingness they hinder the receiving of this sacrament during the day on which it happens. Hence it is written (Dt 23,10): "If there be among you any man, that is defiled in a dream by night, he shall go forth out of the camp; and he shall not return before he be washed with water in the evening."
4. Although the stain of guilt be taken away by contrition and confession nevertheless the bodily defilement is not taken away, nor the mental distraction which follows therefrom.
5. To dream of homicide brings no bodily uncleanness, nor such distraction of mind as fornication, on account of its intense delectation; still if the dream of homicide comes of a cause sinful in itself, especially if it be mortal sin, then owing to its cause it hinders the receiving of this sacrament.



Whether food or drink taken beforehand hinders the receiving of this sacrament?



Objection: 1. It seems that food or drink taken beforehand does not hinder the receiving of this sacrament. For this sacrament was instituted by our Lord at the supper. But when the supper was ended our Lord gave the sacrament to His disciples, as is evident from Lc 22,20, and from 1Co 11,25. Therefore it seems that we ought to take this sacrament after receiving other food.
2. Further, it is written (1Co 11,33): "When you come together to eat," namely, the Lord's body, "wait for one another; if any man be hungry, let him eat at home": and thus it seems that after eating at home a man may eat Christ's body in the Church.
3. Further, we read in the (3rd) Council of Carthage (Can. xxix): "Let the sacraments of the altar be celebrated only by men who are fasting, with the exception of the anniversary day on which the Lord's Supper is celebrated." Therefore, at least on that day, one may receive the body of Christ after partaking of other food.
4. Further, the taking of water or medicine, or of any other food or drink in very slight quantity, or of the remains of food continuing in the mouth, neither breaks the Church's fast, nor takes away the sobriety required for reverently receiving this sacrament. Consequently, one is not prevented by the above things from receiving this sacrament.
5. Further, some eat and drink late at night, and possibly after passing a sleepless night receive the sacred mysteries in the morning when the food it not digested. But it would savor more of moderation if a man were to eat a little in the morning and afterwards receive this sacrament about the ninth hour, since also there is occasionally a longer interval of time. Consequently, it seems that such taking of food beforehand does not keep one from this sacrament.
6. Further, there is no less reverence due to this sacrament after receiving it, than before. But one may take food and drink after receiving the sacrament. Therefore one may do so before receiving it.

On the contrary Augustine says (Resp. ad Januar., Ep. liv): "It has pleased the Holy Ghost that, out of honor for this great sacrament, the Lord's body should enter the mouth of a Christian before other foods."
I answer that A thing may prevent the receiving of this sacrament in two ways: first of all in itself, like mortal sin, which is repugnant to what is signified by this sacrament, as stated above (Article [4]): secondly, on account of the Church's prohibition; and thus a man is prevented from taking this sacrament after receiving food or drink, for three reasons. First, as Augustine says (Resp. ad Januar., Ep. liv), "out of respect for this sacrament," so that it may enter into a mouth not yet contaminated by any food or drink. Secondly, because of its signification. i.e. to give us to understand that Christ, Who is the reality of this sacrament, and His charity, ought to be first of all established in our hearts, according to Mt 6,33: "Seek first the kingdom of God." Thirdly, on account of the danger of vomiting and intemperance, which sometimes arise from over-indulging in food, as the Apostle says (1Co 11,21): "One, indeed, is hungry, and another is drunk."Nevertheless the sick are exempted from this general rule, for they should be given Communion at once, even after food, should there be any doubt as to their danger, lest they die without Communion, because necessity has no law. Hence it is said in the Canon de Consecratione: "Let the priest at once take Communion to the sick person, lest he die without Communion."

Reply to Objection: 1. As Augustine says in the same book, "the fact that our Lord gave this sacrament after taking food is no reason why the brethren should assemble after dinner or supper in order to partake of it, or receive it at meal-time, as did those whom the Apostle reproves and corrects. For our Saviour, in order the more strongly to commend the depth of this mystery, wished to fix it closely in the hearts and memories of the disciples. and on that account He gave no command for it to be received in that order, leaving this to the apostles, to whom He was about to entrust the government of the churches."
2. The text quoted is thus paraphrased by the gloss: "If any man be hungry and loath to await the rest, let him partake of his food at home, that is, let him fill himself with earthly bread, without partaking of the Eucharist afterwards."
3. The wording of this decree is in accordance with the former custom observed by some of receiving the body of Christ on that day after breaking their fast, so as to represent the Lord's supper. But this is now abrogated, because as Augustine says (Resp. ad Januar., Ep. liv), it is customary throughout the whole world for Christ's body to be received before breaking the fast.
4. As stated in the II-II 147,6, ad 2, there are two kinds of fast. First, there is the natural fast, which implies privation of everything taken before-hand by way of food or drink: and such fast is required for this sacrament for the reasons given above. And therefore it is never lawful to take this sacrament after taking water, or other food or drink, or even medicine, no matter how small the quantity be. Nor does it matter whether it nourishes or not, whether it be taken by itself or with other things, provided it be taken by way of food or drink. But the remains of food left in the mouth, if swallowed accidentally, do not hinder receiving this sacrament, because they are swallowed not by way of food but by way of saliva. The same holds good of the unavoidable remains of the water or wine wherewith the mouth is rinsed, provided they be not swallowed in great quantity, but mixed with saliva.Secondly, there is the fast of the Church, instituted for afflicting the body: and this fast is not hindered by the things mentioned (in the objection), because they do not give much nourishment, but are taken rather as an alterative.
5. That this sacrament ought to enter into the mouth of a Christian before any other food must not be understood absolutely of all time, otherwise he who had once eaten or drunk could never afterwards take this sacrament: but it must be understood of the same day; and although the beginning of the day varies according to different systems of reckoning (for some begin their day at noon, some at sunset, others at midnight, and others at sunrise), the Roman Church begins it at midnight. Consequently, if any person takes anything by way of food or drink after midnight, he may not receive this sacrament on that day; but he can do so if the food was taken before midnight. Nor does it matter, so far as the precept is concerned, whether he has slept after taking food or drink, or whether he has digested it; but it does matter as to the mental disturbance which one suffers from want of sleep or from indigestion, for, if the mind be much disturbed, one becomes unfit for receiving this sacrament.
6. The greatest devotion is called for at the moment of receiving this sacrament, because it is then that the effect of the sacrament is bestowed, and such devotion is hindered more by what goes before it than by what comes after it. And therefore it was ordained that men should fast before receiving the sacrament rather than after. Nevertheless there ought to be some interval between receiving this sacrament and taking other food. Consequently, both the Postcommunion prayer of thanksgiving is said in the Mass, and the communicants say their own private prayers.However, according to the ancient Canons, the following ordination was made by Pope Clement I, (Ep. ii), "If the Lord's portion be eaten in the morning, the ministers who have taken it shall fast until the sixth hour, and if they take it at the third or fourth hour, they shall fast until evening." For in olden times, the priest celebrated Mass less frequently, and with greater preparation: but now, because the sacred mysteries have to be celebrated oftener, the same could not be easily observed, and so it has been abrogated by contrary custom.




Whether those who have not the use of reason ought to receive this sacrament?



Objection: 1. It seems that those who have not the use of reason ought not to receive this sacrament. For it is required that man should approach this sacrament with devotion and previous self-examination, according to 1Co 11,28: "Let a man prove himself, and so let him eat of that bread, and drink of the chalice." But this is not possible for those who are devoid of reason. Therefore this sacrament should not be given to them.
2. Further, among those who have not the use of reason are the possessed, who are called energumens. But such persons are kept from even beholding this sacrament, according to Dionysius (Eccl. Hier. iii). Therefore this sacrament ought not to be given to those who have not the use of reason.
3. Further, among those that lack the use of reason are children, the most innocent of all. But this sacrament is not given to children. Therefore much less should it be given to others deprived of the use of reason.

On the contrary We read in the First Council of Orange, (Canon 13); and the same is to be found in the Decretals (xxvi, 6): "All things that pertain to piety are to be given to the insane": and consequently, since this is the "sacrament of piety," it must be given to them.
I answer that Men are said to be devoid of reason in two ways. First, when they are feeble-minded, as a man who sees dimly is said not to see: and since such persons can conceive some devotion towards this sacrament, it is not to be denied them.In another way men are said not to possess fully the use of reason. Either, then, they never had the use of reason, and have remained so from birth; and in that case this sacrament is not to be given to them, because in no way has there been any preceding devotion towards the sacrament: or else, they were not always devoid of reason, and then, if when they formerly had their wits they showed devotion towards this sacrament, it ought to be given to them in the hour of death; unless danger be feared of vomiting or spitting it out. Hence we read in the acts of the Fourth Council of Carthage (Canon 76). and the same is to be found in the Decretals (xxvi, 6): "If a sick man ask to receive the sacrament of Penance; and if, when the priest who has been sent for comes to him, he be so weak as to be unable to speak, or becomes delirious, let them, who heard him ask, bear witness, and let him receive the sacrament of Penance. then if it be thought that he is going to die shortly, let him be reconciled by imposition of hands, and let the Eucharist be placed in his mouth."

Reply to Objection: 1. Those lacking the use of reason can have devotion towards the sacrament; actual devotion in some cases, and past in others.
2. Dionysius is speaking there of energumens who are not yet baptized, in whom the devil's power is not yet extinct, since it thrives in them through the presence of original sin. But as to baptized persons who are vexed in body by unclean spirits, the same reason holds good of them as of others who are demented. Hence Cassian says (Collat. vii): "We do not remember the most Holy Communion to have ever been denied by our elders to them who are vexed by unclean spirits."
3. The same reason holds good of newly born children as of the insane who never have had the use of reason: consequently, the sacred mysteries are not to be given to them. Although certain Greeks do the contrary, because Dionysius says (Eccl. Hier. ii) that Holy Communion is to be given to them who are baptized; not understanding that Dionysius is speaking there of the Baptism of adults. Nor do they suffer any loss of life from the fact of our Lord saying (Jn 6,54), "Except you eat the flesh of the Son of Man, and drink His blood, you shall not have life in you"; because, as Augustine writes to Boniface (Pseudo-Beda, Comment. in 1Co 10,17), "then every one of the faithful becomes a partaker," i.e. spiritually, "of the body and blood of the Lord, when he is made a member of Christ's body in Baptism." But when children once begin to have some use of reason so as to be able to conceive some devotion for the sacrament, then it can be given to them.



Whether it is lawful to receive this sacrament daily?



Objection: 1. It does not appear to be lawful to receive this sacrament daily, because, as Baptism shows forth our Lord's Passion, so also does this sacrament. Now one may not be baptized several times, but only once, because "Christ died once" only "for our sins," according to 1P 3,18. Therefore, it seems unlawful to receive this sacrament daily.
2. Further, the reality ought to answer to the figure. But the Paschal Lamb, which was the chief figure of this sacrament, as was said above (Question [73], Article [9]) was eaten only once in the year; while the Church once a year commemorates Christ's Passion, of which this sacrament is the memorial. It seems, then, that it is lawful to receive this sacrament not daily, but only once in the year.
3. Further, the greatest reverence is due to this sacrament as containing Christ. But it is a token of reverence to refrain from receiving this sacrament; hence the Centurion is praised for saying (Mt 8,8), "Lord, I am not worthy that Thou shouldst enter under my roof"; also Peter, for saying (Lc 5,8), "Depart from me, for I am a sinful man, O Lord." Therefore, it is not praiseworthy for a man to receive this sacrament daily.
4. Further, if it were a praiseworthy custom to receive this sacrament frequently, then the oftener it were taken the more praise-worthy it would be. But there would be greater frequency if one were to receive it several. times daily; and yet this is not the custom of the Church. Consequently, it does not seem praiseworthy to receive it daily.
5. Further, the Church by her statutes intends to promote the welfare of the faithful. But the Church's statute only requires Communion once a year; hence it is enacted (Extra, De Poenit. et Remiss. xii): "Let every person of either sex devoutly receive the sacrament of the Eucharist at least at Easter; unless by the advice of his parish priest, and for some reasonable cause, he considers he ought to refrain from receiving for a time." Consequently, it is not praiseworthy to receive this sacrament daily.

On the contrary Augustine says (De Verb. Dom., Serm. xxviii): "This is our daily bread; take it daily, that it may profit thee daily."
I answer that There are two things to be considered regarding the use of this sacrament. The first is on the part of the sacrament itself, the virtue of which gives health to men; and consequently it is profitable to receive it daily so as to receive its fruits daily. Hence Ambrose says (De Sacram. iv): "If, whenever Christ's blood is shed, it is shed for the forgiveness of sins, I who sin often, should receive it often: I need a frequent remedy." The second thing to be considered is on the part of the recipient, who is required to approach this sacrament with great reverence and devotion. Consequently, if anyone finds that he has these dispositions every day, he will do well to receive it daily. Hence, Augustine after saying, "Receive daily, that it may profit thee daily," adds: "So live, as to deserve to receive it daily." But because many persons are lacking in this devotion, on account of the many drawbacks both spiritual and corporal from which they suffer, it is not expedient for all to approach this sacrament every day; but they should do so as often as they find themselves properly disposed. Hence it is said in De Eccles. Dogmat. liii: "I neither praise nor blame daily reception of the Eucharist."

Reply to Objection: 1. In the sacrament of Baptism a man is conformed to Christ's death, by receiving His character within him. And therefore, as Christ died but once, so a man ought to be baptized but once. But a man does not receive Christ's character in this sacrament; He receives Christ Himself, Whose virtue endures for ever. Hence it is written (He 10,14): "By one oblation He hath perfected for ever them that are sanctified." Consequently, since man has daily need of Christ's health-giving virtue, he may commendably receive this sacrament every day.And since Baptism is above all a spiritual regeneration, therefore, as a man is born naturally but once, so ought he by Baptism to be reborn spiritually but once, as Augustine says (Tract. xi in Joan.), commenting on Jn 3,4, "How can a man be born again, when he is grown old?" But this sacrament is spiritual food; hence, just as bodily food is taken every day, so is it a good thing to receive this sacrament every day. Hence it is that our Lord (Lc 11,3), teaches us to pray, "Give us this day our daily bread": in explaining which words Augustine observes (De Verb. Dom., Serm. xxviii): "If you receive it," i.e. this sacrament, every day, "every day is today for thee, and Christ rises again every day in thee, for when Christ riseth it is today."
2. The Paschal Lamb was the figure of this sacrament chiefly as to Christ's Passion represented therein; and therefore it was partaken of once a year only, since Christ died but once. And on this account the Church celebrates once a year the remembrance of Christ's Passion. But in this sacrament the memorial of His Passion is given by way of food which is partaken of daily; and therefore in this respect it is represented by the manna which was given daily to the people in the desert.
3. Reverence for this sacrament consists in fear associated with love; consequently reverential fear of God is called filial fear, as was said in the I-II 67,4, ad 2; II-II 19,9 II-II 19,11 II-II 19,12; because the desire of receiving arises from love, while the humility of reverence springs from fear. Consequently, each of these belongs to the reverence due to this sacrament; both as to receiving it daily, and as to refraining from it sometimes. Hence Augustine says (Ep. liv): "If one says that the Eucharist should not be received daily, while another maintains the contrary, let each one do as according to his devotion he thinketh right; for Zaccheus and the Centurion did not contradict one another while the one received the Lord with joy, whereas the other said: 'Lord I am not worthy that Thou shouldst enter under my roof'; since both honored our Saviour, though not in the same way." But love and hope, whereunto the Scriptures constantly urge us, are preferable to fear. Hence, too, when Peter had said, "Depart from me, for I am a sinful man, O Lord," Jesus answered: "Fear not."
4. Because our Lord said (Lc 11,3), "Give us this day our daily bread," we are not on that account to communicate several times daily, for, by one daily communion the unity of Christ's Passion is set forth.
5. Various statutes have emanated according to the various ages of the Church. In the primitive Church, when the devotion of the Christian faith was more flourishing, it was enacted that the faithful should communicate daily: hence Pope Anaclete says (Ep. i): "When the consecration is finished, let all communicate who do not wish to cut themselves off from the Church; for so the apostles have ordained, and the holy Roman Church holds." Later on, when the fervor of faith relaxed, Pope Fabian (Third Council of Tours, Canon 1) gave permission "that all should communicate, if not more frequently, at least three times in the year, namely, at Easter, Pentecost, and Christmas." Pope Soter likewise (Second Council of Chalon, Canon xlvii) declares that Communion should be received "on Holy Thursday," as is set forth in the Decretals (De Consecratione, dist. 2). Later on, when "iniquity abounded and charity grew cold" (Mt 24,12), Pope Innocent III commanded that the faithful should communicate "at least once a year," namely, "at Easter." However, in De Eccles. Dogmat. xxiii, the faithful are counseled "to communicate on all Sundays."



Whether it is lawful to abstain altogether from communion?



Objection: 1. It seems to be lawful to abstain altogether from Communion. Because the Centurion is praised for saying (Mt 8,8): "Lord, I am not worthy that Thou shouldst enter under my roof"; and he who deems that he ought to refrain entirely from Communion can be compared to the Centurion, as stated above (Article [10], ad 3). Therefore, since we do not read of Christ entering his house, it seems to be lawful for any individual to abstain from Communion his whole life long.
2. Further, it is lawful for anyone to refrain from what is not of necessity for salvation. But this sacrament is not of necessity for salvation, as was stated above (Question [73], Article [3]). Therefore it is permissible to abstain from Communion altogether.
3. Further, sinners are not bound to go to Communion: hence Pope Fabian (Third Council of Tours, Canon 1) after saying, "Let all communicate thrice each year," adds: "Except those who are hindered by grievous crimes." Consequently, if those who are not in the state of sin are bound to go to Communion, it seems that sinners are better off than good people, which is unfitting. Therefore, it seems lawful even for the godly to refrain from Communion.

On the contrary Our Lord said (Jn 6,54): "Except ye eat the flesh of the Son of Man, and drink His blood, you shall not have life in you."
I answer that As stated above (Article [1]), there are two ways of receiving this sacrament namely, spiritually and sacramentally. Now it is clear that all are bound to eat it at least spiritually, because this is to be incorporated in Christ, as was said above (Question [73], Article [3], ad 1). Now spiritual eating comprises the desire or yearning for receiving this sacrament, as was said above (Article [1], ad 3, Article [2]). Therefore, a man cannot be saved without desiring to receive this sacrament.Now a desire would be vain except it were fulfilled when opportunity presented itself. Consequently, it is evident that a man is bound to receive this sacrament, not only by virtue of the Church's precept, but also by virtue of the Lord's command (Lc 22,19): "Do this in memory of Me." But by the precept of the Church there are fixed times for fulfilling Christ's command.

Reply to Objection: 1. As Gregory says: "He is truly humble, who is not obstinate in rejecting what is commanded for his good." Consequently, humility is not praiseworthy if anyone abstains altogether from Communion against the precept of Christ and the Church. Again the Centurion was not commanded to receive Christ into his house.
2. This sacrament is said not to be as necessary as Baptism, with regard to children, who can be saved without the Eucharist, but not without the sacrament of Baptism: both, however, are of necessity with regard to adults.
3. Sinners suffer great loss in being kept back from receiving this sacrament, so that they are not better off on that account; and although while continuing in their sins they are not on that account excused from transgressing the precept, nevertheless, as Pope Innocent III says, penitents, "who refrain on the advice of their priest," are excused.
