David's Lord

Peter says in Acts 2:34-35, “For David did not ascend into the heavens, but he himself says, "'The Lord said to my lord, "Sit at my right hand, until I make your enemies your footstool."'

Peter was quoting Psalm 110:1.  The word “LORD” is translated from the Hebrew tetragrammaton YHWH. It is the untranslatable and personal name used only for the one God of Israel.  The word “my Lord” is translated from Adoni, and is in respect and reverence to human dignitaries which means owner, master, and lord, but it is never used for the God of Israel, YWHW.  Jesus is in the category of “adoni,” which is “my Lord” and is never used or God, YHWH.  

After Peter quoting Ps. 110:1, he states,

 “Therefore let all Israel be assured of this: God (YHWH) has made this Jesus, whom you crucified, both Lord and Christ” (Acts 2:36).

Once we understand this, we can appreciate and grasp the many unitary monotheistic creeds of the New Testament such as:

“For there is one God and one mediator between God and men, the man Christ Jesus”  (1 Tim 2:5).

"...one Lord, one faith, one baptism, one God and Father of all.... Eph. 4:5-6

"...yet for us there is one God, the Father, from whom all things and for whom we exist, and one Lord, Jesus Christ....."  1 Cor. 8:6

"Or is God the God of Jews only?  Is he not the God of Gentiles also?  Yes, of Gentiles also, since God is one;" Rom. 3:29-30

"Now a mediator involves more than one party; but God is one." Gal. 3:20

"You believe that God is one; you do well.  Even the demons believe - and shudder." James 2:19

The God of Abraham, Isaac, and Jacob is one individual. The creedal passages in the Hebrew scriptures carry the same God in the NT, that of monotheism. The same God is also the Father of Jesus and his Father is his God, the only true God, not only when he walked this earth, but also after his resurrection (John 17:3; John 20:17; Rev. 3:12). 

It is astounding that there are many passages of scripture that teaches YHWH is one God and that He is the God and Father of Jesus, yet such passages are disregarded and left in the dust so one may continue to take other passages of so called "Trinitarian proof texts" out of context, that can only be supported by inference and implication, to try and prove Jesus is God rather than searching for harmony throughout the whole of scripture to come to a true and logical conclusion. I know because, sorry to say, I have been there.

The human Jesus was faithful to his Father as was Moses and David and the prophets and never walked away from the Jewish creed (Deut. 6:4; Mark 12:29).  The Jews, and Jesus himself a Jew, never conceived the idea that God is three in one, nor did he or anyone ever teach it.
