>while the Lord said “It is the Spirit who gives life; the flesh profits nothing; the words that I have spoken to you are spirit and are life,”
He also said "Verily, verily, I say unto you, Except ye eat the flesh of the Son of man, and drink his blood, ye have no life in you."
When Christ says that "flesh profits nothing" he means that material things and material food won't profit you. But Eucharist is not eaten in a sense that this little peace of bread will materialy feed you, but it gives you grace and gives you spiritual life. Augustine comments on this saying: "Yea, but as they understood it, for they understood that the flesh was to be eaten as it is divided piecemeal in a dead body, or as sold in the shambles, not as it is quickened by the spirit (…) Let the spirit draw nigh to the flesh (…) then the flesh profiteth very much: for if the flesh profiteth nothing, the Word had not been made flesh, that It might dwell among us."
>"Do not work for the food that perishes, but for the food that endures to eternal life, which the Son of Man will give to you."
Yeah and the Eucharist literally fits this description to the letter
>How they reconcile this by stating that the Christ's blood and spirit are in the same
Literally no one says that Christ's blood is the same as His spirit, this is metaphysical nonsense. It's so idiotic that it doesn't affirm monophysitism any more than "rhghhhrae" does.
>Additionally the apostles decreed that believers aren't to drink blood, yet they commemorate Christ with the Eucharist, how? Because they viewed it as spiritual food.
Yea, we view it as a sipritual food also. Not that Christ's body and blood is only spiritually there, but in a sense that this food nourishes the soul, not the body. Seriously, from purely materialistic perspective this little piece of bread won't feed anyone
