Slimboyfat I am not sure if your most recent post about Psalm 110:1 is directed to me or not. I did not say the first Christians (such as those who died prior to the year 100 CE) attempted to confuse the identities of YHWH and Jesus. I meant that the attempt began in the 2nd century CE, and in agreement with you I said it seems that the Name "YHWH" began being replaced with the word "Lord" in the Septuagint and in the NT during the 2nd century CE.
However, I now think that if Jesus interpreted Psalm 110:1 the way the gospels said he did, for example in saying that David wrote that verse and that the phrase "my Lord" refers to the Messiah (instead of to King David or any of the Kings of Judah who after him and were also anointed), then Jesus was in error and thus not the divine Christ and not the divine Son of Man and not the divine Son of God.
In reading commentaries (primarily study notes of some study Bibles) about Psalm 110:1 I learned that the verse was part of a coronation song written by someone (or some people) in the court of David and that the expression "my Lord" referred primarily to David, but also to other humans who were said to have sat "on the throne of David" on Earth. This makes sense, instead of the way the Gospels and many Christians apply it, for consider the following.
The kings of Judah (and the united kingdom of Israel), including David, literally ruled among their enemies. Opposed kingdoms existed around the kingdoms of Israel and Judah. The ones who 'sat on the throne David' in Judah thus literally ruled among their enemies. The ancient Jews probably thought that the foretold future Messiah would rule on Earth initially among his human enemies also, but that the Messiah would later conqueror those rival kings. But despite what the WT teaches Jesus has never ruled in that way.
Jesus is not the ruler in a literal sense of any people of Earth (though among believers of Christ he can be thought of as spiritually ruling Christians in their figurative hearts since Pentecost of the year 33 CE, or so). No part of the world has been conquered by Jesus Christ. Every part of the Earth inhabited by humans has a human government or some other human authority over it, instead of being run by a government of Jesus Christ. Even if hypothetically Jesus Christ is alive and in heaven, he is not ruling over any part of the Earth in a literal sense.
Though the governing body of the JW religion (the religion created by the WT) teaches that the WT organization is Jehovah's earthly organization and that Jesus is ruling through the JW governing body, the governing body is still subject to human governments (including the USA federal government, the government of the state of NY, city governments in the USA, and human governments outside of the USA). None of those human governments (except maybe the Vatican) recognize Jesus Christ as king ruling over planet Earth or any part of it. None of them (except maybe the Vatican in the minds of its officials) submit to Jesus Christ as their governmental authority.
Jesus Christ does not communicate to any human rulers. Jesus Christ does not governmental orders or governmental instructions to any human rulers, nor any other way exercising authority over the Earth (such as by supernaturally going to war against any human government or executing people for defying his alleged laws). As a result Jesus Christ can not be correctly said to be the ruler of planet Earth, nor any part of Earth.
No kingdom of Jesus Christ became established in the year 1914 CE in oversight of planet Earth. The WT is very wrong in teaching that Jesus Christ began ruling over the Earth in the year 1914 CE (or any other year, such as in 1874 CE).
