I agree with you, and I think it actually goes even deeper than Jesus quoting the OT. When Jesus speaks, He is not appealing to an external authority. He is speaking as the same Lord who gave it in the first place.
That is why He can say, “You have heard it said… but I say to you.” He is not revising Moses. He is the one who spoke to Moses.
Titus 1:2–3 makes this explicit. God, who cannot lie, promised before the ages began, and at the proper time manifested His word through preaching. That promise before time is not abstract. It is Christ Himself. Paul is saying the same Lord who gave the Law later revealed Himself in the flesh.
So when Jesus interprets Torah, He is not re-reading it. He is revealing its original voice. That is why He can say, “Moses wrote about Me.” The Torah was not merely pointing forward. It was already Christ speaking.
That’s why your use of the word vantage stood out to me. I read it as Christ being the standpoint from which all Scripture is rightly understood. But I’m curious what you had in mind by it. Were you thinking of perspective, fulfillment, or something else?
That’s what I meant by Christ being the vantage point. He is not just the lens through which we read Scripture. He is the author who steps onto the page and explains His own words.
