PD:
well, looking nature up in the Blue Book Bible Ref - "nature" it taken from the greek feminine - -two meanings - "genesis" - "genos" - ref G1078 and G1085 -- meanings 1.-one that follows origin 2. ones lineage where progeny is enumerated 3. course of life, descent 4. same kind or nation - Is this what you want?
In that respect it appears of course, since God/Lord created Jesus, Jesus would have to be the same type as his creator.. after all, our children are the same "type" as we are - human, spirit is spirit, and he did "leave what he was" behind when he came to earth as a human.. - I say spirit ---an individual spiritual entity-- working together with God in a single purpose...
Next thought: Psalms and the Creed
Taken from the New Testament - a lot of years between Psalms and Matthew - and then we have Jesus,Paul,James, Luke, etc words on the subject--
-- just finished looking up sooo many references as to where Jesus is residing now that he is back in the heavens -- taken from the New American Bible - 17 scriptures - repetition for emphasis maybe! - that states Jesus is sitting on the right hand of God and the kicker being when Jesus answered the question about the two sons of Zebedee who wanted to sit on his left and right hand in the kigdom ---- Jesus said - this decision was not his to give but the Father has prepared their place in the kingdom... taking the decision out of Jesus' hands.. Matt 20:23... If Jesus and God were one - there would be an agreement on this issue and Jesus would have said, ok they can have those positions... yet he deferred it to his Father...
Need for mediator:
Another good scripture - deals with a mediator.. why do we need a mediator to plead our case if Jesus and Jehovah/YHWH are the same? John 16:23,24,26
