▼6:64Without the grace and cooperation of the Holy Spirit, the Eucharist will not benefit those who receive it. The graces that come from receiving the Eucharist are received by a response to the graces of the Spirit, who gives life through the Eucharist.(Conte)

▼6:64 The flesh profits nothing: Dead flesh separated from the spirit, in the gross manner they supposed they were to eat his flesh, would profit nothing. Neither doth man’s flesh, that is to say, man’s natural and carnal apprehension, (which refuses to be subject to the spirit, and words of Christ,) profit any thing. But it would be the height of blasphemy, to say the living flesh of Christ (which we receive in the blessed sacarament, with his spirit, that is, with his soul and divinity) profits nothing. For if Christ’s flesh had profitedus nothing, he would never have taken flesh for us, nor died in us nothing, he would never have taken flesh for us, nor died in the flesh for us.(Challoner)

▼6:64 Are spirit and life: By proposing to you a heavenly sacrament, in which you shall receive, in a wonderful manner, spirit, grace, and life, in its very fountain.(Challoner)
