And though they are both memorial services, yet this one thought makes a world-wide difference between them. The bread and meat which the pious Jew ate, when he kept the Passover, and the wine which he drank on that occasion, would strengthen his body, but there was nothing connected with those material substances that would do any special good to his soul. It is different, however, with our Christian festival of the Lord's Supper. And this difference is clearly brought out in what we find in the catechism of our church on this subject. In speaking of this holy sacrament, the question is asked--"What are the benefits whereof we are partakers thereby?" And the answer to this question is--"The strengthening and refreshing of our souls, by the body and blood of Christ, as our bodies are by the bread and wine." Here we see that while the Lord's Supper is a memorial service indeed, it is at the same time something more than that. _And then, the actual bodily presence of Christ with them must have compelled the apostles to understand the words he used on that occasion, in this memorial sense_. They could not possibly have considered him as meaning that the bread and wine which he gave them at that solemn service did, in any mysterious and supernatural way, become his actual flesh and blood; because, these were already before them in the form of his own body. And they could not be in his body and in the bread and wine, at the same time. The sense in which Jesus first used these words--"my body" and "my blood," was clearly the memorial sense. He meant his disciples to understand him as saying "Take this bread in remembrance of my body, which is to be crucified for you;" and "Take this wine in remembrance of my blood which is to be shed for you." This was what he taught the apostles when he first used these words among them; and this was all he taught them; and we have no right to use these words in any other sense till our blessed Lord himself shall give us authority to do so. Let us never forget the word--_remembrance_, as used by our Saviour here. It is the root out of which the whole tree of this solemn service grows. Let us hold on to this root word, and it will save us from the errors into which many have fallen in reference to this subject.
