To begin with, we need to trace back where "Son of God" originated. It originated in the Old Testament or the Hebrew Scriptures and it was applied to the king of Israel.
For example, in Psalm 2:7*, it states:
I will tell of the decree of the Lord:
He said to me, ‘You are my son;
today I have begotten you.
This is addressed to the King of Israel and indicates a special relationship between the King of Israel (Most likely David in this passage) and the God of Israel. Therefore, this is a designation of a special relationship between God and the King.
For another example, 2 Samuel 7:14A states:
I will be a father to him, and he shall be a son to me.
This is a passage regarding Solomon as the new king and God as his father. Again, it indicates that "Son of God" is a special relationship between God and the king.
Therefore, we can see what the title, "Son of God" designates, so let us turn our attention to the Gospel According to Mark, the gospel without a birth story.
When we turn our attention to the beginning of Mark, we see that it begins with the following: "The beginning of the good news of Jesus Christ, the Son of God" (Mk 1:1). Therefore the author of Mark is establishing that Jesus is the Son of God but in what fashion?
This is answered when Jesus is baptized by John the Baptist in the following verses. Mark 1:9-11 states:
In those days Jesus came from Nazareth of Galilee and was baptized by John in the Jordan. And just as he was coming up out of the water, he saw the heavens torn apart and the Spirit descending like a dove on him. And a voice came from heaven, ‘You are my Son, the Beloved; with you I am well pleased.’
Note, what the "voice from heaven" (presumably God) says to Jesus in verse 11: "You are my Son, the Beloved: with you I am well pleased."
What did God say to David in Psalm 2:7? "You are my Son; today I have begotten you."
Incredible. Jesus is the Son of God in that he is the Messiah (Christ [English] = Christos [Greek] = Messiach [Hebrew], which means the "Anointed One") of Israel and later, all nations. However, Jesus is a different type of king, in that his kingdom is the "Kingdom of God," which has all of it's own implications. However, he is anointed by the spirit, just like David was and seemingly given the spirit at his baptism.
This a lot of implications for soteriology (theory or doctrine of salvation) and what the good news of Jesus really is, of which I will explore in a later blog.
As for now, please leave comments and remarks. I open to constructive criticism but please no hate speech or negative remarks about my eternal "soul" and/or character.
