Are really disagreeing? If the carcass is simply the flesh of Jesus to be eaten, and the Holy Spirit is the blood of Jesus to be drunk what would the end result be?
"Not that we are sufficient of ourselves to think any thing as of ourselves; but our sufficiency is of God;
Who also hath made us able ministers of the new testament; not of the letter, but of the spirit: for the letter killeth, but the spirit giveth life." II Cor 3:5-6
The letter as I see it is the dead flesh of Jesus, or the unread or unquickened scriptures. Then comes the quickening Spirit bringing them to Life within a person as per Jesus words:
"Then Jesus said unto them, 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." John 6:53
