An account of a disputation at Oxford, anno dom. 1554 with A treatise of…

The natural substance of the Sacramental Wine remaineth still, and is the material substance of the Sacrament of the Blood of Christ. Therefore it is likewise so in the Sacramental Bread. I know that he that is of the contrary opinion will deny the former part of my argument. But I will prove it thus by the plain words of Christ himself, both in Matth and in Mark. Christ's words be these, after the words said upon the Cup - I say unto you, saith Christ, I will not drink henceforth of this fruit of the Vine-tree, until I shall drink ⟨p. 16⟩that anew in my Fathers Kingdom. Here note how Christ calleth plainly his Cup the Fruit of the Vinetree: but the fruit of the Vine-tree is very natural Wine: wherefore the very natural substance of the Wine doth remain still in the Sacrament of Christ's Blood.

And here in speaking of the Lord's Cup, it cometh to my remembrance the vanity of Innocentius fantastical Invention, which by Pauls words I did confute before, and here did promise somewhat more to speak; and that is thus. If the Transubstantiation be made by this word [Blessed] in Mark said upon the Bread, then surely seeing that word is not said of Christ, (neither of any of the Evangelists, nor of Paul) upon the Cup, then there is no Transubstantiation of the Wine at all: For where the cause doth fail, there cannot follow the Effect. But the Sacramental Bread, and the Sacramental Wine do both remain in their natural Substance alike, and if the one be not changed, (as of the Sacramental Wine it appeareth evidently,) then is there no such Transubstantiation in either of them both.
