If they have no will between them but the Father's then the Father is the only one who matters.
And regardless, since each of them is 100% of God under the Trinity doctrine, why would any version of God submit to another version of God who can't make decisions any different to the other two versions? Unless they have and use distinct wills, there's only one will, traditionally the Father's, and what Jesus or the Ghost might prefer doesn't matter.
That is, the result is exactly the same as if Jesus and the Ghost didn't exist.
In regard their wills, it is the will of the Father that is followed and the Holy Spirit and the Son will to do the Father's will. And of course, they all do exist even if they act in harmony, as one. 3 willing and acting as one. Sounds right. I wonder if they have discussions and disagreements before settling on the course of action.
And no, each of them is not 100 %
of God unless that is counting the Father and HS in Jesus and counting Jesus and the HS in the Father and counting the Father and Jesus in the HS.
They are distinct but not separate. They are always united with each other.
Either Jesus was born by divine insemination of a virgin or he wasn't. The author of Mark was purporting to write an account of Jesus. In his version Jesus is NOT born of a virgin, and doesn't need to be, and can't have been, since he became God's son by adoption, just as David was adopted. You don't need to adopt, or pretend to adopt, your own genetic offspring.
At the baptism God
declared Jesus was His Son and anointed Him with the Holy Spirit so that He could go and preach and do miracles etc.
The earliest witness we have about Jesus is from Paul who was not writing to tell the story of Jesus but who has Jesus as the uncreated pre human with God and who became a man. Even Jesus human birth is not when Jesus became God's Son. Jesus did not need to be born as a human to be the Son of God.
As I keep saying, the author of Mark didn't just not mention it, his story rules it out altogether,
And you have no basis for attributing to any ancient writer knowledge (other than the most general kind) that is not found in what he wrote.
The earliest witness, Paul, shows a knowledge of Jesus pre humanity and His deity.
Mark does not rule anything out.
You want to rule out the idea that Mark saw Jesus as anything more than a nice Jewish lad but you don't seem to realise that the prophecy Mark uses (Mark 1:2,3) is one that says John the Baptist is preparing the way of the LORD. (Isa 40:3) That implies the idea that the Messiah came from heaven and was not a normal human with father and mother.
Mark 1:1 The beginning of the gospel of Jesus Christ, the Son of God.
2 As it is written in Isaiah the prophet,
“Behold, I send my messenger before your face,
who will prepare your way,
3 the voice of one crying in the wilderness:
‘Prepare the way of the LORD,
make his paths straight,’”
In my view, that's untenable wishful thinking. There are at least three distinct models of Jesus in the NT, whether you or I like it or not. They are incompatible, and vary in credibility, Mark's being the closest to credible and the virgin birth tale being the farthest.
The LORD from heaven came as the Son of Man to suffer and die and rise to heaven to be glorified and come back in glory.
Each version of Jesus in the NT expressly denies that he's God and never claims to be God.
That does not appear to be the case when even Mark's gospel call Jesus God in the first few lines, as does Isaiah the prophet.
Only the Jesuses of Paul and of John pre-existed in heaven with God and created the material universe ─ notions, as I've remarked before, from gnosticism, in which Jesus has the role of the demiurge, doing what the absolutely pure spirit of God would never do, create materiality.
The first witness to Jesus in writing (Paul) has the divine Jesus, as does the last, (John) and those in between also.
The Jesuses of Matthew and Luke are also said to be descended from David, but that's nonsense, since the irreconcilable genealogies aren't credible and anyway are for Joseph, expressly NOT the father of Jesus. And of course the Jesus of Mark is not only NOT descended from David but says you don't have to be.
Any Messiah had to have descended from David and Jesus is called the Son of David in Mark.
No, it's not. Paul distinguishes clearly between Jesus' role as Lord, and God's role as God. This is plainly stated in your quotes below, and God is always in charge and Jesus is always [his] senior underling and envoy ─
Jesus is always the Son of God with the nature of His Father and submissive to His Father's will. The Father, Son and Holy Spirit work as one God in what they do.
