St. Augustine: “It is the Spirit that quickens"

"IN another passage of the Scriptures it is said, “The heaven is My throne, and the earth is My footstool.” (Is 66:1) Does he then bid us worship the earth, since in another passage it is said, that it is God's footstool? How then shall we worship the earth, when the Scripture says openly, “You shall worship the Lord your God”? (Dt 6:13) Yet here it says, “fall down before His footstool:” and, explaining to us what His footstool is, it says, “The earth is My footstool.” I am in doubt; I fear to worship the earth, lest He who made the heaven and the earth condemn me; again, I fear not to worship the footstool of my Lord, because the Psalm bids me, “fall down before His footstool.” I ask, what is His footstool? And the Scripture tells me, “the earth is My footstool.” In hesitation I turn unto Christ, since I am herein seeking Himself: and I discover how the earth may be worshipped without impiety, how His footstool may be worshipped without impiety. For He took upon Him earth from earth; because flesh is from earth, and He received flesh from the flesh of Mary. And because He walked here in very flesh, and gave that very flesh to us to eat for our salvation; and no one eats that flesh, unless he has first worshipped: we have found out in what sense such a footstool of our Lord's may be worshipped, and not only that we sin not in worshipping it, but that we sin in not worshipping. But does the flesh give life?

"Our Lord Himself, when He was speaking in praise of this same earth, said, “It is the Spirit that quickens, the flesh profits nothing.”...But when our Lord praised it, He was speaking of His own flesh, and He had said, “Except a man eat My flesh, he shall have no life in him.” (Jn 6:54) Some disciples of His, about seventy, were offended, and said, “This is an hard saying, who can hear it?” And they went back, and walked no more with Him. It seemed unto them hard that He said, “Except you eat the flesh of the Son of Man, you have no life in you:” they received it foolishly, they thought of it carnally, and imagined that the Lord would cut off parts from His body, and give unto them; and they said, “This is a hard saying.” It was they who were hard, not the saying; for unless they had been hard, and not meek, they would have said unto themselves, He says not this without reason, but there must be some latent mystery herein. They would have remained with Him, softened, not hard: and would have learned that from Him which they who remained, when the others departed, learned. For when twelve disciples had remained with Him, on their departure, these remaining followers suggested to Him, as if in grief for the death of the former, that they were offended by His words, and turned back. But He instructed them, and says unto them, “It is the Spirit that quickens, but the flesh profits nothing; the words that I have spoken unto you, they are spirit, and they are life.” (Jn 6:63) Understand spiritually what I have said; you are not to eat this body which you see; nor to drink that blood which they who will crucify Me shall pour forth. I have commended unto you a certain mystery; spiritually understood, it will quicken. Although it is needful that this be visibly celebrated, yet it must be spiritually understood."
