Answer.--This bread signifies the heavenly food and divine perfections. So, "If any man eateth of this bread" means if any man acquires heavenly bounty, receives the divine light, or partakes of Christ's perfections, he thereby gains everlasting life. The blood also signifies the spirit of life and the divine perfections, the lordly splendor and eternal bounty. For all the members of the body gain vital substance from the circulation of the blood.
In the Gospel of St. John, chapter 6, verse 26, it is written: "Ye seek Me, not because ye saw the miracles, but because ye did eat of the loaves, and were filled."
It is evident that the bread of which the disciples ate and were filled was the heavenly bounty; for in verse 33 of the same chapter it is said: "For the bread of God is He which cometh down from heaven, and giveth life unto the world." It is clear that the body of Christ did not descend from heaven, but it came from the womb of Mary; and that which descended from the heaven of God was the spirit of Christ. As the Jews thought that Christ spoke of His body, they made objections, for it is said in the 42nd verse of the same chapter: "And they said, Is not this Jesus, the son of Joseph, whose father and mother we know? how is it then that he saith, I came down from heaven?"
Reflect how clear it is that what Christ meant by the heavenly bread was His spirit, His bounties, His perfections and His teachings; for it is said in the 63rd verse: "It is the spirit that quickeneth; the flesh profiteth nothing."
Therefore, it is evident that the spirit of Christ is a heavenly grace which descends from heaven; whosoever receives light from that spirit in abundance--that is to say, the heavenly teachings--finds everlasting life. That is why it is said in the 35th verse: "And Jesus said unto them, I am the bread of life: he that cometh to Me shall never hunger; and he that believeth on Me shall never thirst."
Notice that "coming to Him" He expresses as eating, and "belief in Him" as drinking. Then it is evident and established that the celestial food is the divine bounties, the spiritual splendors, the heavenly teachings, the universal meaning of Christ. To eat is to draw near to Him, and to drink is to believe in Him. For Christ had an elemental body and a celestial form. The elemental body was crucified, but the heavenly form is living and eternal, and the cause of everlasting life; the first was the human nature, and the second is the divine nature. It is thought by some that the Eucharist is the reality of Christ, and that the Divinity and the Holy Spirit descend into and exist in it. Now when once the Eucharist is taken, after a few moments it is simply disintegrated and entirely transformed. Therefore, how can such a thought be conceived? God forbid! certainly it is an absolute fantasy.
To conclude: through the manifestation of Christ, the divine teachings, which are an eternal bounty, were spread abroad, the light of guidance shone forth, and the spirit of life was conferred on man. Whoever found guidance became living; whoever remained lost was seized by enduring death. This bread which came down from heaven was the divine body of Christ, His spiritual elements, which the disciples ate, and through which they gained eternal life.
The disciples had taken many meals from the hand of Christ; why was the last supper distinguished from the others? It is evident that the heavenly bread did not signify this material bread, but rather the divine nourishment of the spiritual body of Christ, the divine graces and heavenly perfections of which His disciples partook, and with which they became filled.
In the same way, reflect that when Christ blessed the bread and gave it to His disciples, saying, "This is My body,"+F2 and gave grace to them, He was with them in person, in presence, and form. He was not transformed into bread and wine; if He had been turned into bread and wine, He could not have remained with the disciples in body, in person and in presence.
Then it is clear that the bread and wine were symbols which signified: I have given you My bounties and perfections, and when you have received this bounty, you have gained eternal life and have partaken of your share and your portion of the heavenly nourishment.
