For as often as ye shall eat. Paul now adds what kind of remembrance ought to be cherished -- that is, with thanksgiving; not that the remembrance consists wholly in confession with the mouth; for the chief thing is, that the efficacy of Christ's death be sealed in our consciences; but this knowledge should stir us up to a confession in respect of praise, so as to declare before men what we feel inwardly before God. The Supper then is (so to speak) a kind of memorial, which must always remain in the Church, until the last coming of Christ; and it has been appointed for this purpose, that Christ may put us in mind of the benefit of his death, and that we may recognize it [1] before men. Hence it has the name of the Eucharist. [2] If, therefore, you would celebrate the Supper aright, you must bear in mind, that a profession of your faith is required from you. Hence we see how shamelessly those mock God, who boast that they have in the mass something of the nature of the Supper. For what is the mass? They confess (for I am not speaking of Papists, but of the pretended followers of Nicodemus) that it is full of abominable superstitions. By outward gesture they give a pretended approval of them. What kind of showing forth of the death of Christ is this? Do they not rather renounce it? Until he come As we always need a help of this kind, so long as we are in this world, Paul intimates that this commemoration has been given us in charge, until Christ come to judgment. For as he is not present with us in a visible form, it is necessary for us to have some symbol of his presence, by which our minds may exercise themselves.

For as often - Whenever you do this.
Ye eat this bread - This is a direct and positive refutation of the doctrine of the papists that the bread is changed into the real body of the Lord Jesus. Here it is expressly called "bread" - bread still - bread after the consecration. Before the Saviour instituted the ordinance he took "bread" - it was bread then: it was "bread" which he "blessed" and "broke;" and it was bread when it was given to them; and it was bread when Paul says here that they ate. How then can it be pretended that it is anything else but bread? And what an amazing and astonishing absurdity it is to believe that that bread is changed into the flesh and blood of Jesus Christ (transubstantiation or consubstantiation)!
Ye do show the Lord's death - You set forth, or exhibit in an impressive manner, the fact that he was put to death; you exhibit the emblems of his broken body and shed blood, and your belief of the fact that he died. This shows that the ordinance was to be so far public as to be a proper showing forth of their belief in the death of the Saviour. It should be public. It is one mode of professing attachment to the Redeemer; and its public observance often has a most impressive effect on those who witness its observance.
Till he come - Until he returns to judge the world. This demonstrates:
(1) That it was the steady belief of the primitive church that the Lord Jesus would return to judge the world; and,
(2) That it was designed that this ordinance should be perpetuated, and observed to the end of time. In every generation, therefore, and in every place where there are Christians, it is to be observed, until the Son of God shall return; and the necessity of its observance shall cease only when the whole body of the redeemed shall be permitted to see their Lord, and there shall be no need of those emblems to remind them of him, for all shall see him as he is.

Ye do show the Lord's death - As in the passover they showed forth the bondage they had been in, and the redemption they had received from it; so in the eucharist they showed forth the sacrificial death of Christ, and the redemption from sin derived from it.

For as often as ye eat this bread, and drink this cup,.... Not any bread, or any cup: but what is ate and drank in an ordinance way, and according to the institution and appointment of Christ, and with a view to the end proposed by him; and though there is no set fixed time for the administration of this ordinance, yet this phrase seems to suggest that it should be often: and very plainly signifies, that the bread and wine, after the blessing or thanksgiving, remain such, and are not converted into the real body and blood of Christ; but are only outward elements representing these to faith;
ye do show the Lord's death till he come; or rather, as it may be rendered in the imperative mood, as an exhortation, direction or command, "show ye the Lord's death till he come"; since everyone that eats and drinks at the Lord's table does not show forth his death, which is the great end to be answered by it; for the design of the institution of it is to declare that Christ died for the sins of his people: to represent him as crucified; to set forth the manner of his sufferings and death, by having his body wounded, bruised, and broken, and his blood shed; to express the blessings and benefits which come by his death, and his people's faith of interest in them; and to show their sense of gratitude, and declare their thankfulness for them; and all this, "till he come"; which shows the continuance of this ordinance, which is to last till Christ's second coming, where the carnal ordinances of the former dispensation were shaken and removed; and also the continuance of Gospel ministers to the end of the world, to administer it, and of churches to whom it is to be administered: this assures of the certainty of Christ's second coming; as it leads back to his coming in the flesh, suffering and dying in our stead, and thereby obtaining redemption for us; it leads forward to expect and believe he will come again, to put us into the full possession of the salvation he is the author of; when there will be no more occasion for this ordinance, nor any other, but all will cease, and God will be all in all. The apostle here refers to a custom used by the Jews in the night of the passover, to show forth the reason of their practice, and that institution to their children; when either (u).
"the son asked the father, or if the son had not understanding (enough to ask), then the father taught him, saying, how different is this night from all other nights? for in all other nights we eat leavened and unleavened bread, but in this night only unleavened; in all other nights we eat the rest of herbs, but in this night bitter herbs; in all other nights we eat flesh roasted, broiled, and boiled, in this night only roasted; in all other nights we wash once, in this night twice; and as elsewhere (w) it is added, in all other nights we eat sitting or lying, in this night all of us lie; and according to the capacity of the child, the father teaches him,''
particularly he was to inform him what these several things showed forth, or declared (x); as that
"the passover "declared", or "showed forth", that the Lord passed over the houses of our fathers in Egypt; the bitter herbs "showed forth", that the Egyptians made the lives of our fathers bitter in Egypt; and the unleavened bread "declared" that they were redeemed; and all these things are called "the declaration", or showing forth:''
and there is a treatise called , "the showing forth of the passover"; in which, besides the things mentioned, and many others, it is observed (y), that it was commanded the Jews "to declare" the going out of Egypt, and that everyone that diligently declares the going out of Egypt, is praiseworthy: now the apostle observes this end of the Lord's supper, to show forth his death, in opposition to the notion of the "judaizing" Christians at Corinth, who thought of nothing else but the showing forth of the passover, and the declaration of that deliverance and redemption wrought for the people of Israel; whereas the true and only intent of it was to show forth the death of Christ, redemption by him, and the greatness of his love expressed therein, and which is to be continued till his second coming; whereas the time was come when it should "be no more said, the Lord liveth, that brought up the children of Israel out of the land of Egypt", Jeremiah 16:14.

For--in proof that the Lord's Supper is "in remembrance" of Him.
show--announce publicly. The Greek does not mean to dramatically represent, but "ye publicly profess each of you, the Lord has died FOR ME" [WAHL]. This word, as "is" in Christ's institution (1-Corinthians 11:24-25), implies not literal presence, but a vivid realization, by faith, of Christ in the Lord's Supper, as a living person, not a mere abstract dogma, "bone of our bone, and flesh of our flesh" (Ephesians 5:30; compare Genesis 2:23); and ourselves "members of His body, of His flesh, and of His bones," "our sinful bodies made clean by His body (once for all offered), and our souls washed through His most precious blood" [Church of England Prayer Book]. "Show," or "announce," is an expression applicable to new things; compare "show" as to the Passover (Exodus 13:8). So the Lord's death ought always to be fresh in our memory; compare in heaven, Revelation 5:6. That the Lord's Supper is in remembrance of Him, implies that He is bodily absent, though spiritually present, for we cannot be said to commemorate one absent. The fact that we not only show the Lord's death in the supper, but eat and drink the pledges of it, could only be understood by the Jews, accustomed to such feasts after propitiatory sacrifices, as implying our personal appropriation therein of the benefits of that death.
till he come--when there shall be no longer need of symbols of His body, the body itself being manifested. The Greek expresses the certainly of His coming. Rome teaches that we eat Christ present corporally, "till He come" corporally; a contradiction in terms. The showbread, literally, "bread of the presence," was in the sanctuary, but not in the Holiest Place (Hebrews 9:1-8); so the Lord's Supper in heaven, the antitype to the Holiest Place, shall be superseded by Christ's own bodily presence; then the wine shall be drunk "anew" in the Father's kingdom, by Christ and His people together, of which heavenly banquet, the Lord's Supper is a spiritual foretaste and specimen (Matthew 26:29). Meantime, as the showbread was placed anew, every sabbath, on the table before the Lord (Leviticus 24:5-8); so the Lord's death was shown, or announced afresh at the Lord's table the first day of every week in the primitive Church. We are now "priests unto God" in the dispensation of Christ's spiritual presence, antitypical to the HOLY PLACE: the perfect and eternal dispensation, which shall not begin till Christ's coming, is antitypical to the HOLIEST PLACE, which Christ our High Priest alone in the flesh as yet has entered (Hebrews 9:6-7); but which, at His coming, we, too, who are believers, shall enter (Revelation 7:15; Revelation 21:22). The supper joins the two closing periods of the Old and the New dispensations. The first and second comings are considered as one coming, whence the expression is not "return," but "come" (compare, however, John 14:3).

Ye show forth the Lord's death - Ye proclaim, as it were, and openly avow it to God, and to all the world. Till he come - In glory.
