Spirit vs. Flesh
John 6:63 is the one verse singled out by Protestant apologists to counter much of what we have asserted thus far. After seeing the Jews and the disciples struggling with the radical nature of his words, our Lord says to the disciples and to us all: “It is the spirit that gives life, the flesh is of no avail; the words that I have spoken to you are spirit and life.” Protestants claim Jesus here lets us know he was speaking symbolically or “spiritually” when he said “the spirit gives life, the flesh is of no avail.” See? He is not giving us his flesh to eat because he says “the flesh is of no avail.” How do we respond? We can in several ways.
1) If Jesus was clearing up the point, he would have to be considered a poor teacher: Many of the disciples left him immediately thereafter because they still believed the words of our Lord to mean what they said.
2) Most importantly, Jesus did not say, “My fleshis of no avail.” He said, “The fleshis of no avail.” There is a rather large difference between the two. No one, it is safe to say, would have believed he meant my flesh avails nothing because he just spent a good portion of this same discourse telling us that his flesh would be “given for the life of the world” (Jn 6:51, cf. 50-58). So to what was he referring?The flesh is a New Testament term often used to describe human nature apart from God’s grace.
For example, Christ said to the apostles in the Garden of Gethsemane, “Watch and pray that you may not enter into temptation; the spirit indeed is willing, but the flesh is weak” (Mk 14:38). According to Paul, if we are in “the flesh,” we are “hostile to God” and “cannot please God” (cf. Rom 8:1-14). In First Corinthians 2:14, he tells us, “The unspiritual man does not receive the gifts of the Spirit of God, for they are folly to him, and he is not able to understand them because they are spiritually discerned.” In First Corinthians 3:1, Paul goes on, “But I, brethren, could not address you as spiritual men, but as men of the flesh, as babes in Christ.” It requires supernatural grace in the life of the believer to believe the radical declaration of Christ concerning the Eucharist. As Jesus himself said both before and after this “hard saying”: “No one can come to me unless the Father who sent me draws him” (Jn 6:44, cf. 6:65). Belief in the Eucharist is a gift of grace. The natural mind—or the one who is in “the flesh”—will never be able to understand this great Christian truth.
3) On another level very closely related to our last point, Christ said, “It is the spirit that gives life, the flesh is of no avail,” because he wills to eliminate any possibility of a sort of crass literalism that would reduce his words to a cannibalistic understanding. It is the Holy Spirit that will accomplish the miracle of Christ being able to ascend into heaven bodily while being able simultaneously to distribute his body and blood in the Eucharist for the life of the world. A human body, even a perfect one, apart from the power of the Spirit could not accomplish this.
4) That which is spiritual does not necessarily equate to that which has no material substance. It often means that which is dominated or controlled by the Spirit.
One thing we do not want to do as Christians is to fall into the trap of believing that because Christ says his words are “spirit and life,” or “spiritual,” they cannot involve the material. When speaking of the resurrection of the body, Paul wrote: “It is sown a physical body, it is raised a spiritual body” (1 Cor 15:44). Does this mean we will not have a physical body in the resurrection? Of course not. In Luke 24:39, Jesus made that clear after his own Resurrection: “See my hands and my feet, that it is I myself; handle me, and see; for a spirit has not flesh and bones as you see that I have.”
The resurrected body is spiritual,and indeed we can be called spiritualas Christians inasmuch as we are controlled by the Spirit of God. Spiritual in no way means void of the material. That interpretation is more gnostic than Christian. The confusion here is most often based upon confusion between spirit—a noun—and the adjective spiritual. When spirit is used, e.g., “God is spirit” in John 4:24, it is then referring to that which is not material. However, the adjective spiritualis not necessarily referring to the absence of the material; rather, it is referring to the material controlled by the Spirit.
Thus, we could conclude that Jesus’ words, “It is the spirit that gives life, the flesh is of no avail” have essentially a twofold meaning. Only the Spirit can accomplish the miracle of the Eucharist, and only the Spirit can empower us to believe the miracle.
This was written by Jim Staples and I'm not sure where or when. I usually don't post others work but this seemed to express the truth quite well.
