J. H. Newman über die hl. Eucharistie

»Christ has promised He will be with us to the end,—with us, not only as He is in the unity of the Father and the Son, not in the Omnipresence of the Divine Nature, but personally, as the Christ, as God and man; not present with us locally and sensibly, but still really, in our hearts and to our faith. And it is by the Holy Ghost that this gracious communion is effected. How He effects it we know not; in what precisely it consists we know not. We see Him not; but we are to believe that we possess Him,—that we have been brought under the virtue of His healing hand, of His life-giving breath, of the manna flowing from His lips, and of the blood issuing from His side. And hereafter, on looking back, we shall be conscious that we have been thus favoured.« (PPS 6,10)

»The text [Joh 6,50] speaks of the greatest and highest of all the Sacramental mysteries, which faith has been vouchsafed, that of Holy Communion. Christ, who died and rose again for us, is in it spiritually present, in the fulness of His death and of His resurrection. We call His presence in this Holy Sacrament a spiritual presence, not as if "spiritual" were but a name or mode of speech, and He were really absent, but by way of expressing that He who is present there can neither be seen nor heard; that He cannot be approached or ascertained by any of the senses; that He is not present in place, that He is not present carnally, though He is really present. And how this is, of course is a mystery. All that we know or need know is that He is given to us, and that in the Sacrament of Holy Communion.« (PPS 6,11)
