I like what Spurgeon had to say on this...
We are helped to remember it by the type, the emblem, the metaphor which is supplied to us by this supper. How is that?
Is there any likeness to the death of Christ in this supper? I answer,
there is a great likeness.
There is his broken body, represented by the bread which is broken, and intended for use. His dear body was broken, marred, sadly marred, given over to the hands of death, laid in the sepulchre, wrapped about with fine linen, left there, as his enemies thought, never to rise again. In that broken bread, broken that even believing children may eat their morsel, you see Christ's body given up for his people's sake.
But there stands a cup. It is full of the red juice of the grape. What means it? He himself shall explain it: "This cup is the new testament in my blood, which is shed for you." Now, the shedding of blood is the great token of death. One would not long talk of killing without speaking of blood-shedding; in fact, bloodshed usually means dying by a violent death; and so did he die. They pierced his hands and his feet; the soldier thrust his lance into his side, and forthwith came there out blood and water. That stream of blood was the token that he really was dead. He hath poured out from his veins his precious life to purchase his redeemed. The broken bread, the cluster pressed into the cup, and leaving nothing but its blood-red juice, these two things symbolize Christ's death.
But, most of all, this is an exhibition of the two things separate, the bread and the cup. We have heard of some mixing the bread with the wine; that is not the Lord's supper. We have heard of others partaking of the wafer, as they call it, and leaving the cup; this is not taking the Lord's supper. They must be both there; the bread here, the wine-cup there; because the separation of the blood from the flesh is the surest token of death. "The blood is the life thereof;" and if the blood be drained away, there is death. Therefore the blood is represented by the cup, and the flesh is represented by the bread; these two separated are the great token and emblem of Christ's death.
We show, display, exhibit, symbolize, the death of our Lord at this table in this fashion; we partake of both symbols, eating of the bread, drinking of the cup, the whole ministering to the support of our life. At this table we say to all of you who do not know Christ, Christ's death is our life, and the remembrance of Christ's death is the food of our life. If any of you are spectators of the ordinance, this is the meaning of our little acted sermon, Christ has died. Christ's death is the support of our faith, the food of our souls; in token whereof we take this bread and this cup, and eat and drink. So this supper is a showing forth of Christ's death. How many here can say that Christ's death is their life? How many of you can say that you feed upon him? Dear friends, you must not come to the table unless you can say it; but if you can, come and welcome; and if you cannot, oh! may the Lord teach you the lesson that is so needful, the lesson that is so blessed, when it is once learnt, that Christ on the cross is the one hope of eternal glory.
You have thus had two meanings of the Lord's supper; first, it is a memorial; and next, an exhibition.[/quote]
Christ did not command us to do this for exhibition or symbolism rather to "commune in His flesh and His blood" and ontologically be united with Him. As it says ...he who stays in me I stay in him ....there is the ontological union between us and Christ.
It is to no avail if you do not believe in the true presence... of Christ in Eucarist.....
God bless,
Philothei
