Since this article is about biblical study, I suggest you study the verse you posted, which does not say what you claim.
1) Where did Jesus give instructions that the Christian faith should be based exclusively on a book?
2) Other than the specific command to John to pen the Revelation, where did Jesus tell His apostles to write anything down and compile it into an authoritative book?
3) Where in the New Testament do the apostles tell future generations that the Christian faith will be based solely on a book?
4) Where in the Bible do we find an inspired and infallible list of books that should belong in the Bible? Where did the table of contents come from?
5) Where is the concept of ‘Trinity” explained?
6) Where is the concept of ‘Sola Scriptura’ explained?
Just for starters.
That is your opinion. Scripture is infalliable. I take Scripture to mean what it says. I believe "This is my Body" means "This is my Body" You are the one who needs to 'interpret' Scripture to support your man-made beliefs. You change the clear words of Scripture to say "This REPRESENTS my Body" By what authority can you change the words of Scripture?
