By [different men’s opinion] (sic), I take this sageist put-down to mean that you opt for your own opinion—but how much below the surface study is it based on? You might enjoy

Of your numbering, 2 (with vowels) = 5 (without vowels), and 3 is a fudge of 2 long sorted. I doubt that you have delved deeply into how the Bible has presented God’s only name (so F F Bruce) and title (adonai/kurios): in the Greek 4 could stand for Jesus—and for Moses. That Moses was lord (Nb.12:11), no more makes Moses Yahweh, that that the royal king of Ps.110:1 was Yahweh: [the LORD said unto my lord]. But to follow your implied logic: YHWH (Yahweh) is LORD; Moses is LORD; [therefore is] YHWH the LORD God? BTW, your [YHWH the LORD God] is literally [YHWH YHWH God], reduplication lacking meaning, and throwing CAPS around Jesus’ lordship hardly makes your point. The terms Yahweh, Yeshua, and
adonai, are not interchangeable, though there is some intersection at the noncarnate and incarnate levels.
Jesus was not even God, let alone Yahweh! Jesus is God-the-son-incarnate, the man Christ Jesus who has deificity, a deity link. We can both cite [Jesus is
theos] texts: (Jhn.1:1,18; Rm.9:5; Tts.2:13; 2 Pt.1:1). The Q is how to put their envelope terms into systematic meaning when all the biblical data is in.
As to Rm.10:13, the NWT (2013) reads that “…everyone who calls on the name of Jehovah will be saved.” I argue from context that here κυριος refers to Jesus—as I suspect that you do—and that here salvation refers to entering Christ’s kingdom. Jesus as lord remains obedient to his father the ultimate lord, and we may also call the spirit, lord (2 Cor.3:17: David Garland).
