Actually I need to dig a bit here
The nwt and the 2001 using Jehovah in the NT is counter-productive for non trinitarians. The reason is in places like mark 1 the quotation from Malachi and Isaiah say john prepared the way for Jehovah. Sane issues in Roman 10:13 and numerous other places.
Here is why neither the trinity nor the non-trinitarians are correct:
Christianity like grew out of two movements.Qumran and the man of the lie. The later formed gnosticism and this view of the high god being them Father of Jesus and not Jehovah makes sense in the Pauline epistles and parts of John.
The former Qumran believed in El Elyon as the high god the father. Jehovah as his son and the mother Asherah or in later cases Sophia. The spirit. Note in the earliest christian texts. Jesus is only named Jesus upon his death and ressurection. (See Philippians 2) Jehovah saves. The idea of Jehovah dying and rising goes far back into antiquity to the Baal cycle.
