Thomas Aquinas, on 1Cor 11:20

“When you come therefore together into one place, it is not now to eat the Lord’s supper.”

“Then when he says, when you meet together, he accuses them of a third fault, namely, that they sinned in the way and order in which they took the body of Christ. All that follows can be explained in two ways. According to the first explanation they are accused of taking the body of Christ just after eating. In regard to this he does four things: first, he mentions the harm they incur; secondly, he mentions the fault (v. 21); thirdly, he looks for the cause of the fault (v. 22); fourthly, he concludes his rebuke (v. 22b). He says, therefore, first, When you come together, there are factions among you, therefore meeting together in body not in mind, you have come to this which is not, i.e., not lawful or is not becoming for you to eat the Lord's supper, i.e., receive the sacrament of the Eucharist, which the Lord gave His disciples at supper. "For this sacrament," says Augustine On John, "is the sacrament of unity and love." Therefore, it is not suited to dissenters; "Eat, O friends and drink; drink deeply, O lovers" (S. of S. 5:2). Or better: it can be referred to what follows, so that the sense is: not only are there disputes among you when you come together, but it has now become your custom to do what is lawful for you, namely, to eat the Lord's supper, which you approach right after eating. For because the Lord gave this sacrament to His disciples after supper (Matt 26:26), the Corinthians also wanted to take the body of Christ after a common meal. But the Lord did this for three reasons: first, because the figure precedes the truth in proper order. But the paschal lamb was a figure or shadow of this sacrament. Accordingly, after the supper of the paschal lamb, Christ gave this sacrament. For it says in Col (2:17) about all practices of the Law: "These are only a shadow of what is to come; but the substance belongs to Christ." Secondly, in order that from this sacrament He might pass immediately to His passion, of which this sacrament is the memorial. Therefore, he said to the disciples: "Arise, let us go from here," (Jn. 14:31); namely, to His passion. Thirdly, in order that this sacrament be impressed more sharply on the hearts of the disciples, to whom He gave it in His last quiet retreat. But out of reverence for this great sacrament the Church later established that it can be taken only by those fasting; from which the sick were excepted, who in necessity, which knows no law, could take the body of Christ without fasting. But because water does not break the fast, some supposed that after a drink of water they could take this sacrament, especially because, as they say, water is not nourishment any more than any other element. But although water by itself is not nourishment and, therefore, does not break the Eucharistic fast in the sense that some are said to fast, nevertheless when it is mixed with other things, it does nourish. And in this sense some are said to be fasting who on the same day take neither food nor drink. And because the pieces of food remaining in the mouth are consumed after the manner of saliva, this does not prevent one from being fasting. Likewise, the fast is not broken, if a person does not sleep at all during the night, or even if the food is not fully digested, provided that on one and the same day he took absolutely no food or drink. Hence because the beginning of a day is reckoned from midnight according to the custom of the Church, then whoever partakes of food or drink, no matter how little, after midnight, cannot receive this sacrament on that day. According to another explanation, they are reprimanded for a different fault. For in the early church the faithful offered bread and wine, which were consecrated into the body and blood of Christ. After the consecration the rich, who had offered much, wanted the same amount returned; and so they took an abundant share, while the poor, who had offered nothing, received nothing. Therefore, it is for this fault that the Apostle reprimands them, saying: When you meet together, it is not any longer to eat the Lord's supper. For the Lord's supper is common to the whole family; but each of you takes it not as common but as his own, while he tries to justify himself, because he offered it to God. And this is what he adds: Each one presumes, i.e., presumptuously attempts to eat the supper, namely of the Lord, i.e., consecrated bread and wine, as his own, i.e., taking them as though they were his own, namely, the things consecrated to the Lord, for their use.”
