First: Jesus is not a person of the trinity.
Secondly: We do not have three divine dieties, or, divinities that are all God Almighty. There is and has always been ONE divinity that is THE only true Diety, and that is Jehovah. Jesus is not and has never been equal to the Father and still has made his mark on humanity, and this does not mean that this situation is polytheistic. In the Jews' own scriptures Jehovah and His Son appear in the texts. (E.g., Psalm 2:2-12; Psalm 110:1-7; Isaiah 11:1-5; Isaiah 61:1,2.) To the Jews this was not polytheistic.
Next, your number 2: Jesus, truly, is not God. He is a creature of less divine nature, indeed. Every person ever created is of lesser nature than Jehovah.
Your number 3: Jesus died for our sins after an extensive history of being involved with humanity. He CREATED humans (Colossians 1:16), with his Father's power and authorization of course, and he afterward stood in as his Father's spokesman to all of the ancients. He was totally involved in everything humans ever did. And Jesus and Jehovah are not "unknown beings." They both are explained in the Bible. It is all there for anyone to see. Why would anyone say that Jesus gave up his life unwillingly? There is nothing in the scriptures to suggest such a thing. Your issues are dissolving before your eyes.
1. I was not talking about a trinity. Father is a god and appears, through your comments, that Jesus is a god. Then you have Holy Spirit. Well mentioned and respected for past 2k years or so since "in the name of the Father, Son, and Holy [Spirit]." but you say there is no trinity. So we potentially have 3 gods that existed before time and angels and everything else. why would this make sense? because despite saying Jesus is not a god ( let alone the God)...for having everything that The Father has but unknown percentage of unknown thing(s) that are not the same, Jesus would be a whole lot like a diety by description.
2. of lesser nature...so lets consider what Jesus is. Sure not human, but maybe still part human and part divine? This reflects on what I say above and earlier. You describe Jesus as a diety who created humans but he is not the creator of all things or considered a god? there is no logic in that. If Jesus is not the god or any god and not a diety then...Jesus is comparable to either Hurcules or some other diety in human history that is worshipped but not glorified.
For Jews. Jesus was just a man. nothing else. either a prophet or liar because he sure would not be their messiah.

If their Messiah was not Jesus and would still be human, then Id still have to wonder what Jesus is.
3. Things dont appear to be as you speak or what you speak does not appear to be as things are or was.
The reason I said unknown beings is because your explanations are not spanning out.
Otherwise lets consider, " why has thou foresaken me?" Jesus is quoted in saying it. its in the Bible. Athiests and other theists have used it to identify that Jesus was not a willing party. I do not believe this, but may be argued from a standpoint.
