No, I do not see where you are going. When you stray from a literal, grammatical, syntactical, historical, cultural hermeneutic, you just open a gateway that the Holy Scripture does not use except when it explains itself clearly and succinctly. This method takes you where the Scripture does not, and calls on allegorical inventions to play the game of trying to convince others of some portion of Scripture The God has not given to you to understand.
By forcing a non-literal interpretation on the masses, a body of customs is born that needs more and more props, until one has a religion that stands more on reasonings, claimed experiences, and "traditions" of fallible men, not on special revelation through Scripture.
By doing so, God's communication to mankind is lost and one has only the "gospel" of a false Christ. IMHO
How do we discern a literal, grammatical, syntactical, historical, cultural hermeneutic using the Bible alone --much less follow it?
Must we all become intellectual, first century Jews to be Christian? To what do we appeal, what from the Bible will tell us, when there is no explicit text, which of the several senses of ειμι and ιστημι apply to a particular saying?
If Jesus says,
τουτο εστιν το σωμα μου... Τουτο εστιν το αιμα μου της διαθηκης...
what in Scripture will tell us what sense of εστιν applies?
Or should we say, "He said those words, so I believe him, even though they appear to be just bread and wine."
Jesus used a lot of material objects to describe Himself—He said, “I am the Light.” “I am the Door.” “I am the Shepherd.”
But He never said, “That light is Me.” “That door is Me.” “That shepherd is Me.”
However, He did say, “That Bread is Me. That Wine is Me.”
You either believe Christ or you think he is a liar.
Your choice.
The Eucharist is Jesus Christ, Truly Present; Body, Blood, Soul, and Divinity, because Jesus SAID SO, in the Bible.
