Reply Obj. 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 (John 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 1 Cor. 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. _______________________
TENTH ARTICLE [III, Q. 80, Art. 10]
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 1 Pet. 3:18. Therefore, it seems unlawful to receive this sacrament daily.
Obj. 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 (Q. 73, A. 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.
Obj. 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 (Matt. 8:8), "Lord, I am not worthy that Thou shouldst enter under my roof"; also Peter, for saying (Luke 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.
Obj. 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.
Obj. 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."
