I’ve had professors (who were trained in England/American institutions and obviously Evangelical) be very adamant about the veil being torn and therefore we have access to God in such a way we SHOULD say Yahweh. Then I have professors (secular and Evangelical) who’ve studying in Jerusalem and prefer adoni (LORD).
Again, there is the veil of the entrance into the holy of holies. Four pillars there are, the sign of the sacred tetrad of the ancient covenants. Further, the mystic name of four letters which was affixed to those alone to whom the adytum was accessible, is called Jave (Ίαουε), which is interpreted,Who is and shall be.The name of God, too, among the Greeks contains four letters. (Stromata 5.6).
Waltke writes of the matter:
“As an aside, let me explain why I uniquely, in a biblical theology, render God’s personal name- which is represented by the four Hebrew consonants YHWH- as “I AM,” not as “Jehovah,” “Yahweh” (as I did in my Genesis commentary) [n]or “LORD” (as I did in my Proverbs commentary). Providence has not preserved the vocalization of this tetragrammaton (“four letters”). Scribes, who in the Second Temple period preserved and transmitted the Scriptures, read the tetragramation as adoni. YHWH cannot be pronounced. That was the scribes’ intention but not the original author’s intention. “Jehovah” confounds the vowels of adoni with the four consonants. Yahweh, though the probable normalization, is nevertheless speculative. Moreover, it seems to demote the status of the living God to that of just another ancient Near Eastern deity, like Marduk of the Babylonains or Asshur of the Assyrians. This normalization alienates God from the modern reader- at least, so it seems to me.” (emphasis his)
