“The words that I have spoken to you are spirit and life.”
I’m still unsure. What does this even mean if not referencing a pure symbolism?
“the flesh is no help at all”
Also, what does this mean in any context?
63 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. (John 6:63)
I think the key to understanding what Jesus means in John 6:63 is to read something similar that St Paul wrote:
12 Now we have received not the spirit of the world, but the Spirit which is from God, that we might understand the gifts bestowed on us by God. 13 And we impart this in words not taught by human wisdom but taught by the Spirit, interpreting spiritual truths to those who possess the Spirit.
14 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. 15 The spiritual man judges all things, but is himself to be judged by no one. (1 Corinthians 2:12-15)
“It is the spirit that gives life, the flesh is of no avail…”: The flesh, that is, the things of this world in themselves are not spiritually life-giving; the Spirit, that is, the gifts of the Spirit of God, are spiritually life-giving. The gifts of the Spirit of God are spiritually discerned through faith. The unspiritual person, relying solely on what he can perceive with his senses, on his flesh, cannot receive the gifts of the Spirit of God, he is not able to understand them, they are folly to him.
“…the words that I have spoken to you are spirit and life”: The teaching that you must eat Jesus, eat his flesh and drink his blood, is a spiritual truth that concerns a gift of the Spirit of God, which is spiritually life-giving and spiritually discerned through faith. It concerns a gift that the unspiritual person, relying solely on what he can perceive with his senses, cannot receive or understand. Jesus was talking about a spiritual reality that can only be discerned through faith.
This is all a general description of a sacrament, “an efficacious sign of grace…by which divine life is dispensed to us through the work of the Holy Spirit.” To the unspiritual person, the sacrament of Baptism is nothing more than a quick washing with water; to the spiritual person, Baptism is also, through the work of the Spirit, a spiritual washing away of sins, a spiritual rebirth, etc. To the unspiritual person, Confirmation and the Anointing of the Sick are nothing more than the application of a little oil; to the spiritual person Confirmation is also, through the work of the Spirit, a strengthening of the spiritual gifts received at Baptism and the Anointing of the Sick is also, through the work of the Spirit, at the least a spiritual healing. To the unspiritual person Confession is simply a brief conversation; to the spiritual person Confession is also, through the work of the Spirit, an absolution of sins. To the unspiritual person the Eucharist is just a pitiful little snack, a bit of common bread and a sip of wine; to the spiritual person the Eucharist is also, through the work of the Spirit, Jesus Christ really present under the appearance of bread and wine offering himself to us in a most loving, intimate and humble way so that we might participate in his sacrifice on the cross that redeemed us, freed and continues to free us from the power of sin and death, etc.
