You share the Tetragrammaton opinion with Michael Hoffman, a Catholic man who has mentored me and whom I admire.
That said, as I read Exodus 3:14 in the Vulgate, Douay-Rheims, and Septuagint, I reach a different conclusion.
God said to Moses: I AM WHO AM. He said: Thus shalt thou say to the children of Israel: HE WHO IS, hath sent me to you.
Dixit Deus ad Moysen : Ego sum qui sum. Ait : Sic dices filiis Israel : Qui est, misit me ad vos.
καὶ εἶπεν ὁ Θεὸς πρὸς Μωυσῆν λέγων· ἐγώ εἰμι ὁ ὤν. καὶ εἶπεν· οὕτως ἐρεῖς τοῖς υἱοῖς ᾿Ισραήλ· ὁ ὢν ἀπέσταλκέ με πρὸς ὑμᾶς.
I read this as God describing Himself, not Him telling Moses (and us) His Name.
If you have Magisterium that infallibly defines "__fill in the blank__" as His Name, I would love to see it. Though I have not done a deep dive on this precise question, I have never seen anything reaching the level of Magisterium, only opinion.
Like you, it irritates me that anyone tampers with even one iota of God's Word and I object to any Scriptural substitutions.
Like you, I object to the superstitions that the тαℓмυdists attach to Exodus 3:14, hyphens: circuмlocutions, and the rest of their satanic occultism, including their claim that saying His Name backwards would undo all of Creation.
Even if "Yahweh" is His Name, in numerous Scriptural verses God encourages us to make His Name known, proclaim His Name, and call upon His Name, not to hide it, profane it, or tamper with it.
So, if you have a Magisterial source about Exodus 3:14 as His Name, not merely His Self-description, I would welcome it. Unlike the damned Judaizers infesting CathInfo, I welcome correction of my errors.
I have attached an article that may be of interest to you.
