There is here no such identity of language as would justify the assertion that the change described is of the same nature in each case, that because it leaves the substance of the water and the ointment untouched, therefore the substance of the Bread also must, according to Cyril, remain unchanged:  this must be proved by other arguments.  We must also remember that if this argument based upon the identity of the language used on the two sides of a comparison is trustworthy, there is another passage in Cyril to which it may be applied:  “He once, in Cana of Galilee, changed the water into wine akin to blood (οἰκεῖον αἵματι) On this reading, see Mystag. iv. § 2, note 4., and is it incredible that He changed wine into blood?”  The change of the water into wine was a change of substance:  are we then prepared to agree with the Roman Church that the change of the bread also is a change of substance?  Nay further, would the Roman Church itself accept the principle of the argument?  For observe that in fact Bishop Cosin himself, when he comes to deal with this passage, gives up his former argument, and distinctly rejects it.  “Protestants,” he says, “do freely grant and firmly believe that the wine, in the sense already often mentioned, is changed into the Blood of Christ; but every change is not a transubstantiation; neither doth Cyril say that this change (i.e. of the wine) is like that of the water, for then it would appear to our senses; but that He who changed the water sensibly can also change the wine sacramentally, will not be doubted by any Of Transubstantiation, Ch. vi. § 14..”  Again, in describing the act of consecration, Cyril says:  “We beseech the merciful God to send forth His Holy Spirit upon the gifts lying before Him, that He may make the bread the Body of Christ, and the wine the Blood of Christ, for certainly whatsoever the Holy Ghost has touched, is sanctified and changed (ἡγίασται καὶ μεταβέβληται ) Mystag. v. § 7..”  Here again, as in the passage quoted from Myst. iii. § 3, a sacramental change of some sort is asserted, but its specific character is not defined.
