John 6:53

Except ye eat the flesh . . . and drink the blood . . . no life, &c.--The harshest word He had yet uttered in their ears. They asked how it was possible to eat His flesh. He answers, with great solemnity, "It is indispensable." Yet even here a thoughtful hearer might find something to temper the harshness. He says they must not only "eat His flesh" but "drink His blood," which could not but suggest the idea of His death--implied in the separation of one's flesh from his blood. And as He had already hinted that it was to be something very different from a natural death, saying, "My flesh I will give for the life of the world" (Joh 6:51), it must have been pretty plain to candid hearers that He meant something above the gross idea which the bare terms expressed. And farther, when He added that they "had no life in them unless they thus ate and drank," it was impossible they should think He meant that the temporal life they were then living was dependent on their eating and drinking, in this gross sense, His flesh and blood. Yet the whole statement was certainly confounding, and beyond doubt was meant to be so. Our Lord had told them that in spite of all they had "seen" in Him, they "did not believe" (Joh 6:36). For their conviction therefore he does not here lay Himself out; but having the ear not only of them but of the more candid and thoughtful in the crowded synagogue, and the miracle of the loaves having led up to the most exalted of all views of His Person and Office, He takes advantage of their very difficulties and objections to announce, for all time, those most profound truths which are here expressed, regardless of the disgust of the unteachable, and the prejudices even of the most sincere, which His language would seem only designed to deepen. The truth really…

In this chapter we have, I. The miracle of the loaves (Joh 6:1-14). II. Christ's walking upon the water (Joh 6:15-21). III. The people's flocking after him to Capernaum (Joh 6:22-25). IV. His conference with them, occasioned by the miracle of the loaves, in which he reproves them for seeking carnal food, and directs them to spiritual food (Joh 6:26, Joh 6:27), showing them how they must labour for spiritual food (Joh 6:28, Joh 6:29), and what that spiritual food is (v. 30-59). V. Their discontent at what he said, and the reproof he gave them for it (Joh 6:60-65). VI. The apostasy of many from him, and his discourse with his disciples that adhered to him upon that occasion (Joh 6:66-71).

6:53-58 eat the flesh . . . drink his blood: Jesus answered the question the people asked (6:52). His words hinted at the Lord’s Supper yet to come (see Luke 22:19). Since “flesh and blood” was a Jewish idiom for the whole person, Jesus might have been calling people to consume him fully by completely believing in him. Some Christian traditions see the bread as Christ’s literal flesh broken for us and the wine as his literal blood poured out for us. Others take the meaning in purely spiritual terms. Either way, receiving communion means no less than embracing Jesus’ life-giving sacrifice.
