While Shaw’s work highlights that ΙΑΩ was known and used in certain Jewish contexts, this evidence does not prove it was the original or predominant rendering of YHWH in the LXX.
Neither did I claim that it does. You are not reading what I wrote. Shaw’s work shows that use of the divine name Yaho was widespread among ordinary Jews. This refutes the idea that use of the divine name would not have been familiar for first century Jews when the early Christians used it. On the subject of what was written in the LXX, as I understand it, Shaw’s view is that there was diversity of forms from early in the LXX.
- If the NT authors did not consider the possibility that readers might “confuse” YHWH with Jesus, they wrote with a level of carelessness that fundamentally undermines the inspiration and sacredness of their writings.
The NT authors went out of their way to show that Jesus is Lord in a completely different sense than God. For example, Psalm 110.1 is the most quoted OT text in the NT, precisely because it makes the distinction between Jehovah God and Jesus as messianic Lord crystal clear. It says:
Jehovah declared to my Lord:“Sit at my right handUntil I place your enemies as a stool for your feet.”
Notice here that “Jehovah” (YHWH) is speaking to the messiah as “Lord” (adonai) and that the messianic Lord is clearly subordinate to God. That is how the early Christians distinguished between God and Jesus and is why this text fitted their purpose so well. This careful distinction is also maintained in Phil 2 where Jesus is given the title Lord “to the glory of God the Father.” God himself is not Lord “to the glory of another”. God is almighty in his own glory. Again this text clearly distinguishes Jesus from God and subordinates him to God.
In what sense is Jesus Lord? The NT itself says that Jesus is our Lord because he died and bought us with his blood. That makes Jesus our “owner” which is what his Lordship means in this context. This is spelled out in 2 Peter 2.1 and Jude 4. It is also the basis for the distinction between the honour due to God in Revelation 4 and the honour due to Jesus in Revelation 5. In Revelation 4 God is worthy of honour and glory because he is the one who lives forever, who created all things and because of his will they exist and were created. In chapter 5 Jesus, the lamb of God, is worthy of honour and glory because he died and gave his life that he might buy back humans from sin and death. So again, clearly, Jesus as the owner and Lord of saved humans is Lord in a very different sense from Jehovah who is the ever living God of creation.
