CTA ~ John 6 v52 - 54

52. The Jews therefore strove among themselves, saying, How can this man give us his flesh to eat?

53. 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.

54. Whoso eateth my flesh, and drinketh my blood, hath eternal life; and I will raise him up at the last day.

AUGUSTINE. (Tr. xxvi. s. 14) The Jews not understanding what was the bread of peace, strove among themselves, saying, How can this man give us His flesh to eat? Whereas they who eat the bread strive not among themselves, for God makes them to dwell together in unity.

BEDE. The Jews thought that our Lord would divide His flesh into pieces, and give it them to eat: and so mistaking Him, strove.

CHRYSOSTOM. (Hom. xlvii. 1) As they thought it impossible that He should do as He said, i. e. give them His flesh to eat, He shews them that it was not only possible, but necessary: Then said Jesus 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.

AUGUSTINE. (Tr. xxvi. 15) As if He said, The sense in which that bread is eaten, and the mode of eating it, ye know not; but, Except ye eat the flesh of the Son of man, and drink His blood, ye have no life in you.

BEDE. And that this might not seem addressed to them alone, He declares universally, Whoso eateth My flesh, and drinketh My blood, hath eternal life.

AUGUSTINE. (Tr. xxvi. 15) And that they might not understand him to speak of this life, and make that an occasion of striving, He adds, Hath eternal life. This then he hath not who eateth not that flesh, nor drinketh that blood. The temporal life men may have without Him, the eternal they cannot. This is not true of material food. If we do not take that indeed, we shall not live, neither do we live, if we take it: for either disease, or old age, or some accident kills us after all. Whereas this meat and drink, i. e. the Body and Blood of Christ, is such that he that taketh it not hath not life, and he that taketh it hath life, even life eternal.

THEOPHYLACT. (in v. 52) For it is not the flesh of man simply, but of God: and it makes man divine, by inebriating him, as it were, with divinity.

AUGUSTINE. (de Civ. Dei, l. xxi. c. 25.) There are some who promise men deliverance from eternal punishment, if they are washed in Baptism and partake of Christ’s Body, whatever lives they live. The Apostle however contradicts them, where he says, The works of the flesh are manifest, which are these; adultery, fornication, uncleanness, lasciviousness, idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies, envyings, murders, drunkenness, revellings, and such like; of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God. (Gal. 5:19. et seq.) Let us examine what is meant here. He who is in the unity of His body, (i. e. one of the Christian members,) the Sacrament of which body the faithful receive when they communicate at the Altar; he is truly said to eat the body, and drink the blood of Christ. And heretics and schismatics, who are cut off from the unity of the body, may receive the same Sacrament; but it does not profit them, nay, rather is hurtful, as tending to make their judgment heavier, or their forgiveness later. Nor ought they to feel secure in their abandoned and damnable ways, who, by the iniquity of their lives, desert righteousness, i. e. Christ; either by fornication, or other sins of the like kind. Such are not to be said to eat the body of Christ; forasmuch as they are not to be counted among the members of Christ. For, not to mention other things, men cannot be members of Christ, and at the same time members of an harlot.

AUGUSTINE. (super Joan. c. xxvi. 15) By this meat and drink then, He would have us understand the society of His body, and His members, which is the Church, in the predestined, and called, and justified, and glorified saints and believers. The Sacrament whereof, i. e. of the unity of the body and blood of Christ, is administered, in some places daily, in others on such and such days from the Lord’s Table: and from the Lord’s Table it is received by some to their salvation, by others to their condemnation. But the thing itself of which this is the Sacrament, is for our salvation to every one who partakes of it, for condemnation to none. To prevent us supposing that those who, by virtue of that meat and drink, were promised eternal life, would not die in the body, He adds, And I will, raise him up at the last day; i. e. to that eternal life, a spiritual rest, which the spirits of the Saints enter into. But neither shall the body be defrauded of eternal life, but shall be endowed with it at the resurrection of the dead in the last day.
