"This is the Bread which cometh down from heaven, that a man may eat thereof and not die." John vi. 50.
Now, with reference to the text and the chapter from which it is taken, I begin by observing, what at first sight one would think no one could doubt, that this chapter of St. John does treat of the Lord's Supper, and is, in fact, a comment upon the account of it, given by the other three Evangelists. We know it is St. John's way to supply what his brethren omit, and that especially in matters of doctrine; and in like manner to omit what they record. Hence, while all three give an account of the institution of Holy Communion at the last Supper, St. John omits it; and, because they omit to enlarge upon the great gift contained in it, he enters upon it. This, I say, is his rule: thus, for instance, St. Matthew and St. Mark give an account of the accusation brought against our Lord at His trial, that He had said He could destroy and build again the Temple of God in three days. They do not inform us when He so said; accordingly, St. John supplies the omission; and, while he passes over the charge at the time of His trial, he relates in his second chapter the circumstances some years before out of which it was framed. The Jews had come to Him and asked Him for a sign; then said He, referring in His mind to His resurrection which was to be, "Destroy this Temple, and in three days I will raise it up;" meaning by Temple His own body, and by His raising it up His resurrection, after He had been put to death.
