This Sunday we celebrate the sacrament of the Lord's Supper in the morning service. Here is a passage from John Calvin's Institutes
for you to meditate on as you prepare to receive the sacrament:
The sacrament, therefore, does not make Christ become for the first time the bread of life; but, while it calls to remembrance that Christ was made the bread of life that we may constantly eat him, it gives us a taste and relish for that bread, and makes us feel its efficacy. For it assures us, first, that whatever Christ did or suffered was done to give us life; and, secondly, that this quickening is eternal; by it we are ceaselessly nourished, sustained, and preserved in life. For as Christ would not have not been the bread of life to us if he had not been born, if he had not died and risen again; so he could not now be the bread of life, were not the efficacy and fruit of his nativity, death, and resurrection, eternal. All this Christ has elegantly expressed in these words, “The bread that I will give is my flesh, which I will give for the life of the world” (John 6:51); doubtless intimating, that his body will be as bread in regard to the spiritual life of the soul, because it was to be delivered to death for our salvation, and that he extends it to us for food when he makes us partakers of it by faith. Wherefore he once gave himself that he might become bread, when he gave himself to be crucified for the redemption of the world; and he gives himself daily, when in the word of the gospel he offers himself to be partaken by us, inasmuch as he was crucified, when he seals that offer by the sacred mystery of the Supper, and when he accomplishes inwardly what he externally designates.
