No, Hammer, man is BOTH spirit and flesh. It is a rank falsity to say "we are spirit, not flesh". If that were so, Jesus would have had no need to be incarnated, nor would the Word have been made FLESH to dwell among us.
And, because we are spirit and flesh - with the latter in its fallen state subject to death and corruption - God feeds us with His own (living and incorruptible) Flesh and Blood, so that we might have Life (Who is Jesus Himself), and have it TO THE FULL. What Jesus meant when He said, "you must eat my flesh" is exactly what those words mean: "you must eat my flesh" if you are to have life within you. Yes, He was INDEED speaking of the Living Bread "that we eat with our mouths".
It is IMPOSSIBLE that Jesus was speaking metaphorically when He said, “Except you eat the flesh of the Son of man and drink His blood, you shall not have LIFE in you…” (John 6:54).
It CANNOT be the case, because the expressions to “eat flesh” and to “drink blood” already had a long and well established metaphorical meaning for Jews - and, given what they meant (metaphorically), just about every person listening to Jesus in John 6 would’ve known that He couldn’t POSSIBLY be speaking METAPHORICALLY about their need to eat His body and drink His blood!
You see, the metaphorical meaning of those expressions (“eat flesh” and “drink blood”), for Jews (and for Arabs - even to this day), is to wage war against a person (“eat his flesh”) and do harm to that person (“drink his blood”).
So if Jesus was speaking METAPHORICALLY, He would’ve been talking absolute NONSENSE! He would’ve been saying, “Unless you wage war against me and do harm to me, you will suffer eternal death!” That’s how ABSURD His words would’ve been!
Indeed, there are numerous verses in Scripture itself – containing words spoken by GOD HIMSELF - which amply demonstrate the METAPHORICAL meaning of “eating flesh” and “drinking blood”. Below are a few.
Isaiah 9 (Judgments upon Israel for their sins.)
9:19. By the wrath of the Lord of hosts the land is troubled, and the people shall be as fuel for the fire: no man shall spare his brother.
9:20. And he shall turn to the right hand, and shall be hungry: and shall eat on the left hand, and shall not be filled: every one shall eat the flesh of his own arm: Manasses Ephraim, and Ephraim Manasses, and they together shall be against Juda. (Meaning: they’ll fight against each other, but also fight simultaneously against Juda).
49:26. And I will feed thy enemies with their own flesh: and they shall be made drunk with their own blood, as with new wine: (Meaning: they’ll fight and harm/kill each other) and all flesh shall know, that I am the Lord that save thee, and thy Redeemer the Mighty One of Jacob.
Jeremiah 19 (Prophecy of desolation for the Jews)
19:9. And I will feed them with the flesh of their sons, and with the flesh of their daughters: and they shall eat every one the flesh of his friend (Meaning: they’ll turn on each other) in the siege, and in the distress wherewith their enemies, and they that seek their lives, shall straiten them.
2:2. That the Lord would bring upon us great evils, such as never happened under heaven, as they have come to pass in Jerusalem, according to the things that are written in the law of Moses:
2:3. That a man should eat the flesh of his own son, and the flesh of his own daughter. (Just like Jesus has prophesied for our own times, that over matters of the faith a man will turn against his father, and daughter against her mother, etc… Matt 10:35).
39:17. And thou, O son of man, saith the Lord God, say to every fowl, and to all the birds, and to all the beasts of the field: Assemble yourselves, make haste, come together from every side to my victim, which I slay for you, a great victim upon the mountains of Israel: to eat flesh, and drink blood.
39:18. You shall eat the flesh of the mighty, and you shall drink the blood of the princes of the earth, of rams, and of lambs, and of he goats, and bullocks, and of all that are well fed and fat.
Daniel Chapter 7 (Daniel's vision of the four beasts, signifying four kingdoms: of God sitting on his throne: and of the opposite kingdoms of Christ and Antichrist.)
7:1. In the first year of Baltasar, king of Babylon, Daniel saw a dream: and the vision of his head was upon his bed: and writing the dream, he comprehended it in a few words: and relating the sum of it in short, he said:
7:2. I saw in my vision by night, and behold the four winds of the heavens strove upon the great sea.
7:3. And four great beasts, different one from another, came up out of the sea.
(Four great beasts. . .Viz., the Chaldean, Persian, Grecian, and Roman empires.)
7:4. The first was like a lioness, and had the wings of an eagle: I beheld till her wings were plucked off, and she was lifted up from the earth, and stood upon her feet as a man, and the heart of a man was given to her.
7:5. And behold another beast, like a bear, stood up on one side: and there were three rows in the mouth thereof, and in the teeth thereof, and thus they said to it: Arise, devour much flesh (Meaning: wage war on these four godless empires).
Micah 3 (For the sins of the rich oppressing the poor, of false prophets flattering for lucre, and of judges perverting justice, Jerusalem and the temple shall be destroyed.)
3:1. And I said: Hear, O ye princes of Jacob, and ye chiefs of the house of Israel: Is it not your part to know judgment,
3:2. You that hate good, and love evil: that violently pluck off their skins from them and their flesh from their bones?
3:3. Who have eaten the flesh of my people (Meaning: persecuted them), and have flayed their skin off them: and have broken, and chopped their bones as for the kettle, and as flesh in the midst of the pot.
11:9. And I said: I will not feed you: that which dieth, let it die: and that which is cut off, let it be cut off: and let the rest devour every one the flesh of his neighbour.
11:16. For behold I will raise up a shepherd in the land, who shall not visit what is forsaken, nor seek what is scattered, nor heal what is broken, nor nourish that which standeth, and he shall eat the flesh of the fat ones, and break their hoofs.
14:21. It is good not to eat flesh and not to drink wine (Meaning: have dissensions among yourselves, slander, attack or do harm to each other): nor any thing whereby thy brother is offended or scandalized or made weak.
James 5 (A woe to the rich that oppress the poor. Exhortations to patience and to avoid swearing. Of the anointing the sick, confession of sins and fervour in prayer.)
5:1. Go to now, ye rich men: weep and howl in your miseries, which shall come upon you.
5:2. Your riches are corrupted: and your garments are motheaten.
5:3. Your gold and silver is cankered: and the rust of them shall be for a testimony against you and shall eat your flesh like fire (Meaning: harm you). You have stored up to yourselves wrath against the last days.
19:16. And he hath on his garment and on his thigh written: KING OF KINGS AND LORD OF LORDS.
