The Jews therefore strove one with another ( ἐμάχοντο represents more vigorous demonstration of their difficulties than the ἐγόγγυζον of John 6:41). They were not unanimous in their judgment. Some said one thing, and others said another. The "Jews" had not yet come to a unanimous opinion that this wonderful Being was talking sheer heresy or incomprehensible mystery. They knew his habit of metaphoric speech, and that underneath common imagery he was in the habit of conveying doctrines the full purport of which was not at once apparent. Some denounced him as uttering an intolerable riddle. Some saw, in a measure, through it, and hated the doctrine that was thereby conveyed. How could he be so essential to the life of the world? and how, said the pure materialist, "how can he give us his flesh to eat?" A question of great interest arises. He has already identified, in John 6:35, "coming to him," "reaching him" under the drawing of the Father, with the transcendent blessing of life eternal, of victory, over death, and resurrection. In John 6:40 "beholding" and "believing" are cognate or equivalent conditions of life and resurrection. In John 6:47, again, "believing," per se, is the essential and all-comprehensive condition. Now, has Christ added, in this verse, anything fresh to the fundamental ideas? Let it be pondered that he has already equated "believing" with eating a bread that endureth to everlasting life (John 6:27-29). He has declared himself to be the "Bread of life," and to be appropriated by "coming" and "believing." He has spoken of himself as "living Bread," which, coming for the life of the world from heaven itself, is offered as food. Now, what more than this has he said when he declared that he will offer his "flesh" as heavenly food? The Jews undoubtedly show, by their mutual contest, that he had put some part of the previous oracle in a still more enigmatical, if not offensive, form. So far the imagery was not altogether beyond them. Here it takes on a form which excites angry controversy. If they understood him to mean "doctrine," "truth," "cause," even "office," as Head of a spiritual school—as one providing by his gracious will ample nutriment for all who would eat of the rich banquet of his words—they would, to some extent, follow him. The eating of the tree of life was a well known figure in Hebrew Scripture (Proverbs 4:17; Proverbs 9:5); cf. the language of Isaiah (Isaiah 55:2), the action of Ezekiel (Ezekiel 3:1-3), and the imagery of Hosea (Hosea 10:13). In the "Midrash on Ecclesiastes 2:24; Ecclesiastes 3:12; Ecclesiastes 8:15," "eating and drinking" is said always to refer to the Law (Edersheim and Wunsche). But when he spoke of giving his "flesh" for the life of the world, he passed beyond the limits of their interpreting power. They did not see through his imagery; nor did Jesus exactly answer the angry query which they were putting one to another.
Jesus said to them, Verily, verily, I say unto you, Except ye have eaten the flesh of the Son of man, and have drunk his blood, ye have not life in yourselves. He that eateth ( τρώγων, "eateth with pleasure, eagerness," is repeated four times, as perhaps a stronger expression than φάγων) my flesh and drinketh my blood, hath eternal life; and I will raise him up at the last day. This result, it should be seen, is identical with the promises made to "beholding," "coming," "believing." Life and resurrection will really follow these acts and conditions; but then it is obvious that "beholding," "coming," "believing," must veritably cover what is contained in this last statement. There is no mere tautology. These words express more fully the original condition. They are not new conditions, but a further imaginative exposition of the former ones. The believing involves an assimilation into the very substance of the believer's nature of that which he here specifies as "flesh and blood." Reuss and Luthardt, and to some extent Moulton, admit that by "flesh and blood" he means no more than "flesh;" that under "flesh" is included "blood;" that by both he simply means "himself." Lunge urges that by "flesh" is meant "human nature"—his "manhood;" but by "flesh and blood" (see Matthew 16:17; Galatians 1:16), "inherited nature"—the humanity of Christ in "historical manifestation." But he passes on to say that this manifestation culminates, is completed, in death, and, thus completed, the life of Christ is the nourishment of the real life of man. Tholuck: "The addition of αἷμα to σὸρξ only expresses, by its main constituents, the sensible human nature." The great bulk of interpreters take the additional mention of drinking of his blood to connote an entire acceptance of the atoning sacrifice, of the Paschal blood shedding, to be effected for the deliverance of the world. "Eating of the flesh," then, would mean acceptance of his humanity, of the manifestation of the eternal love in the Son of man; and "drinking his blood" would mean entire mental assimilation also of the terrible culmination of his mission in violent, sacrificial death. This momentous condition of life eternal is stated both negatively and positively. Without the participation in this twofold aspect of the Lord and his work, there is no life. Unless "coming to him," "believing on him," means an acceptance of his humanity, an apprehension of that Personality in whom the Word was incarnate, and an utter surrender of the soul to the rending of that flesh and shedding of the blood which is the life, i.e. to the death of the Son of man, it is not the coming to him and believing on him of which he has already spoken. He that does thus eat and drink will satisfy a craving after nourishment and refreshment. Unless a man consciously or unconsciously accepts, absorbs, the sublime and wondrous gift of the Divine humanity from the second Man, the Lord from heaven, rather than from the first man, he has no life in himself. Human nature apart item the new creation and the new beginning is a dying, not a living, entity. The new life quickened by the Incarnation is not all that Christ would give. The blood of the Son of man, to be accepted in the same way. is a further exposition of the object of faith. The "eating" and "drinking" are therefore phrases which portray the very intimate and close form of that contact with, and dependence upon, the incarnation and the sacrifice of the Son of God, which Christ erewhile defines in broader, vaguer metaphor. A great question has arisen on these verses—whether our Lord is pointing to, or making prophetic reference to, the institution of the Eucharist, about which the fourth evangelist is strangely silent. £ Certain of the early Fathers—Chrysostom, Cyril, and Theophylact—have given it this meaning, though the great bulk of the patristic writers—Ignatius, Irenseus, Origen, Clemens Alex., Tertullian, and even Cyprian—do most obviously interpret the passage itself of direct and spiritual, not the indirect and sacramental manducation of the living Bread. The same view is presented by Eusebius, Athanasius, and Cyril of Alexandria. For the first four centuries all that was done was to apply the argument of John 6:1-71., in order to press the importance of communicating sacramentally. This led the Romanist writers to go further, and regard the participation in the sacramental body and blood as essential to life eternal. Pope Innocent I., Bishop of Rome, A.D. 402, was the first distinguished man who brought up out of this passage "the necessity of communicating infants;" and from the time of his synodical epistle the Latin Chinches interpreted the passage, "Except you receive the Eucharist, you have no life in you." The views of Augustine were vacillating or are dubious. Fulgentius shows that he had, to some extent, broken loose from this narrow view when he concluded that baptism without the Eucharist did convey all the benefits of the body and blood of Christ. Numerous Schoolmen rejected the sacramental interpretation, and the Reformers most justly repudiated it. Luther, Melancthon, Beza, Grotius, Owen, Lampe, Cocceius, asserted that the whole construction of the passage, which treats "coming," "believing," as the complete conditions of life and resurrection, must not be held to transform an, as yet, uninstituted ceremonial into the sole method of "believing." Notwithstanding this wide protest, the opponents of the authenticity of the Fourth Gospel—Bretschneider, Strauss, Baur, Thoma, Hilgenfeld, and numerous others—see in this passage the conception of a mystically disposed second-century divine, who placed the Eucharistic ceremony in the lips of Jesus long before the institution. But while this view can be without hesitation rejected, it is obvious that there was a spiritual participation in the "humanity" and the "sacrifice" of the Son of God which Christ called upon the Capernaites to experience—one which must have been possible to Old Testament saints, to little children; to all who are acceptable to God and accepted by him. Such participation is, without doubt, aided and rendered peculiarly possible, thinkable, in the Eucharist. These words were timed, therefore, to bear the rich and twofold sense of Holy Scripture.
