I think it’s best to just define it as they did.
Jesus was the son of God.
Which god was Jesus the son of? Well he’s the son of the god we see throughout the entire Tanakh presumably.
So Jesus is the son of his father and his father was the god Yahweh.
So we read of the son known as Jesus in the Tanakh walking around? No. Sole try to make that link but it appears Jesus, the son of the god known as Yahweh, was born sometime around the early first century.
How was the son of God able to preform miracles? Was it because of his own divine power? Nope. You don’t read that. You read this .
John 3:35
The Father loves the Son and has given all things into His hand.
Ephesians 1:20
which He brought about in Christ, when He raised Him from the dead and seated Him at His right hand in the heavenly places,
Matthew 28:18
And Jesus came up and spoke to them, saying, “All authority has been given to Me in heaven and on earth.
We also see that at some point Jesus will hand it all back over to his god and his father which is Yahweh. Jesus knew of one god. Yahweh. If you asked Jesus is god he would say my father is the god Yahweh.
1 cor 15:24
then comes the end, when He hands over the kingdom to the God and Father, when He has abolished all rule and all authority and power.
We also know that Jesus made this response once.
Mark 10:18
But Jesus said to him, “Why do you call Me good? No one is good except God alone.
