Christ is His actual son having
the same nature = Deity
and always has been
just as - analogy - your physical body =
same attributes (nature) of your physical father
though your body came to be by procreation
Where from the scriptures is it ever stated that one called "The Son of God" had the same nature or essence as God?
You will not find it anywhere in the OT Jewish scriptures and in fact both David and Solomon were called by the title of "God's Son" and do you even know why they were?
It is because the term "Son of God" refers to the one who would inherit (as if they were a son by nature) the throne of God over the Kingdom of Israel and that is what it meant to be called "God's Son".
So where did the Jews get this idea that it was blasphemy for Jesus to call himself this, for their OT scriptures never revealed this to them, so who did?
You will find that answer from the words of Jesus himself in John 8 below.
John 8:42 Jesus said to them, “If God were your Father, you would love me, for I have come here from God. I have not come on my own; God sent me. 43 Why is my language not clear to you? Because you are unable to hear what I say. 44 You belong to your father, the devil, and you want to carry out your father’s desires. He was a murderer from the beginning, not holding to the truth, for there is no truth in him. When he lies, he speaks his native language, for he is a liar and the father of lies. 45 Yet because I tell the truth, you do not believe me! 46 Can any of you prove me guilty of sin? If I am telling the truth, why don’t you believe me? 47 Whoever belongs to God hears what God says. The reason you do not hear is that you do not belong to God.”
Notice in the bold orange underlined above the real source of the beliefs about Jesus of the apostate Jews, it was the Devil and not their OT scriptures which are God's actual word and the Devil is a liar and a murderer and the Father of it.
Then notice what Jesus went on to say in the bold blue underlined and answer this question, from what source do we hear the word of God Eve?
Isn't from the actual scriptures themselves?
So then you need to answer this question, where are you getting what you believe, for I just showed you that this idea of yours that Jesus calling himself God's Son never meant that one called this was a real Son of God in the sense of essence or actual nature?
Notice, David was first call God's Son by God himself and as he himself declared the decree given unto him by God on this in Psalm 2:7 and then after him, Solomon David's anointed to the throne son was also called God's Son by God himself as well in 2 Samuel 7:14and again, these two men were anointed to inherit the throne of God over the Kingdom of Israel.
This is what God's word reveals about what it means to be called God's Son, but where are you getting what you believe about it, is it from the apostate Jews and what they falsely believed about it from their Father the Devil or the apostate churches of our day which also believe his lies?
