That this was also the teaching of Cyril’s contemporaries is clear from the famous passage of Gregory of Nyssa, in which this doctrine is fully developed.  It will be sufficient to quote here the latter part of the passage, in which Gregory is speaking of the Wine.  “Since then that God-containing flesh partook for its substance and support of this particular nourishment also, and since the God who was manifested infused Himself into perishable humanity for this purpose, viz. that by this communion with Deity mankind might at the same time be deified, for this end it is that, by dispensation of His grace, He disseminates Himself in every believer through that flesh whose substance comes from bread and wine, blending Himself with the bodies of believers, to secure that, by this union with the immortal, man too may be a sharer in incorruption.  He gives these gifts by virtue of the benediction through which He transelements the natural quality of these visible things to that immortal thing Oratio Catechetica, c. xxxvii.  The whole chapter should be read with the Rev. W. Moore’s notes in this Series, Vol. V. pp. 504–506..”
