23 Let me go over with you again exactly what goes on in the Lord's Supper and why it is so centrally important. I received my instructions from the Master himself and passed them on to you. The Master, Jesus, on the night of his betrayal, took bread. 24 Having given thanks, he broke it and said, This is my body, broken for you. Do this to remember me. 25 After supper, he did the same thing with the cup: This cup is my blood, my new covenant with you. Each time you drink this cup, remember me. 26 What you must solemnly realize is that every time you eat this bread and every time you drink this cup, you reenact in your words and actions the death of the Master. You will be drawn back to this meal again and again until the Master returns. You must never let familiarity breed contempt.
27 Anyone who eats the bread or drinks the cup of the Master irreverently is like part of the crowd that jeered and spit on him at his death. Is that the kind of "remembrance" you want to be part of? 28 Examine your motives, test your heart, come to this meal in holy awe. 29 If you give no thought (or worse, don't care) about the broken body of the Master when you eat and drink, you're running the risk of serious consequences. 30 That's why so many of you even now are listless and sick, and others have gone to an early grave.

Commentary on 1 Corinthians 11:23-34
(Read 1 Corinthians 11:23-34)
The apostle describes the sacred ordinance, of which he had the knowledge by revelation from Christ. As to the visible signs, these are the bread and wine. What is eaten is called bread, though at the same time it is said to be the body of the Lord, plainly showing that the apostle did not mean that the bread was changed into flesh. St. Matthew tells us, our Lord bid them all drink of the cup, Matthew 26:27, as if he would, by this expression, provide against any believer being deprived of the cup. The things signified by these outward signs, are Christ's body and blood, his body broken, his blood shed, together with all the benefits which flow from his death and sacrifice. Our Saviour's actions were, taking the bread and cup, giving thanks, breaking the bread, and giving both the one and the other. The actions of the communicants were, to take the bread and eat, to take the cup and drink, and to do both in remembrance of Christ. But the outward acts are not the whole, or the principal part, of what is to be done at this holy ordinance. Those who partake of it, are to take him as their Lord and Life, yield themselves up to him, and live upon him. Here is an account of the ends of this ordinance. It is to be done in remembrance of Christ, to keep fresh in our minds his dying for us, as well as to remember Christ pleading for us, in virtue of his death, at God's right hand. It is not merely in remembrance of Christ, of what he has done and suffered; but to celebrate his grace in our redemption. We declare his death to be our life, the spring of all our comforts and hopes. And we glory in such a declaration; we show forth his death, and plead it as our accepted sacrifice and ransom. The Lord's supper is not an ordinance to be observed merely for a time, but to be continued. The apostle lays before the Corinthians the danger of receiving it with an unsuitable temper of mind; or keeping up the covenant with sin and death, while professing to renew and confirm the covenant with God. No doubt such incur great guilt, and so render themselves liable to spiritual judgements. But fearful believers should not be discouraged from attending at this holy ordinance. The Holy Spirit never caused this scripture to be written to deter serious Christians from their duty, though the devil has often made this use of it. The apostle was addressing Christians, and warning them to beware of the temporal judgements with which God chastised his offending servants. And in the midst of judgement, God remembers mercy: he many times punishes those whom he loves. It is better to bear trouble in this world, than to be miserable for ever. The apostle points our the duty of those who come to the Lord's table. Self-examination is necessary to right attendance at this holy ordinance. If we would thoroughly search ourselves, to condemn and set right what we find wrong, we should stop Divine judgements. The apostle closes all with a caution against the irregularities of which the Corinthians were guilty at the Lord's table. Let all look to it, that they do not come together to God's worship, so as to provoke him, and bring down vengeance on themselves.
