Meaning
Of all the Christological titles used in the New Testament, Son of God has had one of the most lasting impacts in Christian history and has become part of the profession of faith by many Christians.
The New Testament quotes Psalm 110 extensively as applying to the Son of God. A new theological understanding of Psalm 110:1 and 110:4, distinct from that of Judaism, evolved. Jesus himself quotes Psalm 110 in Luke 20:41–44, Matthew 22:41–45, and Mark 12:35–37. The meanings and authenticity of these quotations are debated among modern scholars. Various modern critical scholars reject that David wrote this psalm. In the Masoretic Text many Psalm including this one are explicitly attributed to David. The superscription is "of David a psalm." Some have suggested that this indicates that Psalm 110 was not written by David. The superscription as it stands is ambiguous. However, Jewish tradition ascribes Psalm 110 and indeed all Psalms to king David. In Christianity, David is considered to be a prophet. The New Testament records several psalms as having been spoken through David by the Holy Spirit. Acts 2:29–30 explicitly calls David a prophet. Jesus himself affirms the authorship of this psalm by David in Mark 12:36 and Matthew 22:43. In the Christian reading, David the king is presented as having a lord other than the Lord God. The second lord is the Messiah, who is greater than David, because David calls him "my lord". In Hebrew, the first "Lord" in Psalm 110 is Yahweh (יהוה), while the second is referred to as adoni (אדני, 'my adon'), a form of address that in the Old Testament is used generally for humans but also, in Judges 6:13, for the theophanic Angel of the Lord. The Greek-speaking Jewish philosopher Philo, a contemporary of Jesus, identified the Angel of the Lord with his version of the logos distinct from the later Christian logos.
It is debated when exactly Christians came to understand Psalm 110 as introducing a distinction of persons in the Godhead and indicating that Jesus was more than a human or angelic messiah, but also a divine entity who was David's lord. Hebrews 1:13 again quotes Psalm 110 to prove that the Son is superior to angels. Psalm 110 would play a crucial role in the development of the early Christian understanding of the divinity of Jesus. The final reading of Psalm 110:1 incorporated a preexistent Son of God greater than both David and the angels. The Apostles' Creed and the Niceno-Constantinopolitan Creed would all included references to Psalm 110:1.
Psalm 2:7 reads:
I will tell of the decree of the Lord:
He said to me, "You are my son; today I have begotten you. Ask of me, and I will make the nations your heritage, and the ends of the earth your possession. You shall break them with a rod of iron, and dash them in pieces like a potter's vessel."
Psalm 2 can be seen as referring to a particular king of Judah, but has also been understood to reference the awaited Messiah. In the New Testament, Adam, and, most notably, Jesus Christ References to Psalm 2 in the New Testament are less common than Psalm 110. The passages in Acts, Hebrews and Romans that refer to it give the appearance of being linked with Jesus' resurrection and/or exaltation. Those in the Gospels associate it with Jesus' baptism and transfiguration. The majority of scholars believe that the earliest Christian use of this Psalm was in relation to his resurrection, suggesting that this was initially thought of as the moment when he became Son, a status that the early Christians later extended back to his earthly life, to the beginning of that earthly life and, later still, to his pre-existence, a view that Aquila Hyung Il Lee questions.
The terms sons of God and son of God appear frequently in Jewish literature, and leaders of the people, kings and princes were called "sons of God". What Jesus did with the language of divine sonship was first of all to apply it individually (to himself) and to fill it with a meaning that lifted "Son of God" beyond the level of his being merely a human being made like Adam in the image of God, his being perfectly sensitive to the Holy Spirit (Luke 4:1, 14, 18), his bringing God's peace (Luke 2:14; Luke 10:5–6) albeit in his own way (Matthew 10:34, Luke 12:51), or even his being God's designated Messiah.
In the New Testament, the title "Son of God" is applied to Jesus on many occasions. It is often used to refer to his divinity, from the beginning of the New Testament narrative when in Luke 1:32–35 the angel Gabriel announces: "the power of the Most High shall overshadow thee: wherefore also the holy thing which is begotten shall be called the Son of God."
The declaration that Jesus is the Son of God is echoed by many sources in the New Testament. On two separate occasions the declarations are by God the Father, when during the Baptism of Jesus and then during the Transfiguration as a voice from Heaven. On several occasions the disciples call Jesus the Son of God and even the Jews scornfully remind Jesus during his crucifixion of his claim to be the "Son of God."
However, the concept of God as the father of Jesus, and Jesus as the exclusive divine Son of God is distinct from the concept of God as the Creator and father of all people, as indicated in the Apostles' Creed. The profession begins with expressing belief in the "Father almighty, creator of heaven and earth" and then immediately, but separately, in "Jesus Christ, his only Son, our Lord", thus expressing both senses of fatherhood within the Creed.
