Jesus is distinguished from Jehovah, not from “the Father”, in scripture, including in Psalm 110.
110 Jehovah saith unto my Lord, Sit thou at my right hand,
Until I make thine enemies thy footstool.
2 Jehovah will [send forth the rod of thy strength out of Zion:
Rule thou in the midst of thine enemies.
This verse is quoted many times throughout the New Testament and each and every time Jesus, as “Lord”, is distinguished from Jehovah.
Trinitarian slicing and dicing of scripture and the meaning of “God” is wild and shows no regard for what the text actually says.
If I made the statement “Jesus is not Jehovah”, you’d probably say that is heresy.
Yet when the Bible says that Jesus is not Jehovah, you say something like: “What you’ve got to understand is that ‘Jehovah’ here just means ‘the Father’, and the Trinity teaches that Jesus is not the Father, so there is absolutely nothing wrong with this statement ‘Jesus is not Jehovah’ from a Trinitarian point of view.”
Psalm 110 shows that Jesus, as Lord and Messiah, is distinguished from Jehovah God. Attempting to mix and redefine “God” and “Jehovah” for each verse in order to prop up a later Trinitarian dogma is desperate.
