52. Having summed up the preceding portion of His discourse, Christ now proceeds to declare _how_ He is the bread of life. Till now He had contented Himself with declaring that He is that bread, and with pointing out the chief disposition necessary to receive Him worthily; now He goes further, and points out _how_ He will be the bread of life; namely, by giving His flesh, that is, His whole human nature (i. 14), to which the Divine nature is inseparably united, to be received in the Blessed Eucharist. Thus He gradually unfolds the mystery, reserving till the last supper the further knowledge, that this reception of His body and blood was to take place in a sacramental manner. *And the bread that I will give is my flesh, for the life of the world.* Many Greek MSS. read: “And the bread that I will give is My flesh, _which I will give_ for the life of the world.” If the words “which I will give” be genuine, we would explain them not in reference to the sacrifice of the cross, but in reference to the sacrifice of the Eucharist, in which Christ is given for us and to us. Compare St. Luke: “This is My body, which is _given for you_” (Luke, xxii. 19), and especially Luke xxii. 20, where the Greek text shows that it is the blood _as in the chalice_ (and not as on Calvary) that is said to be offered in sacrifice. But the words more probably are not genuine; they are omitted by Lachmann, Tischendorf, Tregelles, Westcott, and Hort, and by the Revised Version, as well as by the Vulgate. Though not merely Christ’s flesh, that is, His humanity (i. 14), but also His Divinity, is received in the Blessed Eucharist, His human nature is specially mentioned, lest it should be thought that He is the living bread only as God, or merely spiritually. “Dixerat enim,” says St. Thomas on this verse. “Quod erat panis vivus; et ne intelligatur quod hoc ei esset in quantum est Verbum, vel secundum animam tantum, ideo ostendit quod etiam caro sua vivificativa est: est enim organum divinitatis suae: unde, cum instrumentum agat virtute agentis, sicut divinitas Christi vivificativa est, ita et caro virtute Verbi adjuncti vivificat; unde Christus tactu suo sanabat infirmos.” Besides, as St. Thomas adds, since this Sacrament is commemorative of our Lord’s Passion (“For as often as you shall eat this bread, and drink the chalice, you shall show the death of the Lord,” 1 Cor. xi. 26), His “flesh” is mentioned to remind us of the weakness of that human nature wherein it was possible for Him who was God to suffer.
