Anyone who understands the use of the Holy Scriptures to guide other believers also knows that the use involves the interpretation, the hermeneutic of them, and performed by fallible unregenerated-by-faith expositors results in a fallible, unreliable exegesis. Which of this passage, the Catholic presumption is. Your continual insuistence ofthis interpretation is more of an incantation than an explanation.
And it has to be, for you cannot really explain it. It has neither a natural or Scriptural explanation. You don't know how transubstantiation happens, because it doesn't, and is just an illogical superstition contrary to Jesus' assurance that the Holy Spirit would show His Saints all things.
No, I can't explain miracles but I can point to the Holy Scripture that describes it. Luke 22:19, and other synoptics.
