I am the living bread which came down from heaven: if any man eat of this bread, he shall live forever: and the bread that I will give is My flesh, which I will give for the life of the world. -John 6:51

Behold the whole mystery of the sacred Eucharist. It is bread and wine which are lively emblems of the body and blood of Jesus. The power to excite remembrance consists in the appeal thus made to the senses. Here the eye, the hand, the mouth, find joyful work. The bread is tasted, and entering within, works upon the sense of taste, which is one of the most powerful. The wine is sipped-the act is palpable. We know that we are drinking, and thus the senses, which are usually clogs to the soul, become wings to lift the mind in contemplation. Again, much of the influence of this ordinance is found in its simplicity. How beautifully simple the ceremony is-bread broken and wine poured out. There is no calling that thing a chalice, that thing a paten, and that a host. Here is nothing to burden the memory-here is the simple bread and wine. He must have no memory at all who cannot remember that he has eaten bread, and that he has been drinking wine. Note again, the mighty pregnancy of these signs-how full they are of meaning. Bread broken-so was your Saviour broken. Bread to be eaten-so His flesh is meat indeed. Wine poured out, the pressed juice of the grape-so was your Saviour crushed under the foot of divine justice: His blood is your sweetest wine. Wine to cheer your heart-so does the blood of Jesus. Wine to strengthen and invigorate you-so does the blood of the mighty sacrifice. Oh! make that bread and wine to your souls a sweet and blessed help of remembrance of that dear Man who once on Calvary died. Like the little ewe lamb, you are now to eat your Master’s bread and drink from His cup. Remember the hand which feeds you. ~C.H. Spurgeon
