Here is a direct translation from Hebrew:
This is the man Jesus telling us, that in the beginning, the SoulOfGod (Word - authority) and the SpiritOfGod (HolySpirit - power) determined that I would manifest them in the flesh.
Remember, Joh 1:1 tells us that the Word and Spirit are 1 God.
The SpiritOfGod is the Father of Christ Jesus. So, the HolySpirit is Father.
Breaking this down to even simpler terminology:
This verse does not support trinitarianism.
There is One God who is SpiritSoulAndBody just as man is who was created in His image and that God is the LordJesusChrist.
The next verse clarifies any misunderstanding about the nature of our One God.
