This verse was claimed to indicate the Second Person of the Trinity "became" the Son of God when His incarnate bodily resurrection occurred. Totally bogus claim.
Christ's bodily resurrection made obvious or acknowledged that Jesus was indeed the Son of God.
By His resurrection He fulfilled David's prophecy found Psalm 16:10, Jesus, the Son of God's body was not abandoned.
Wrong.
The original post clearly stated in the first sentence that Jesus was always the Son of God. The post asked how we should understand Romans 1:3,4.
QUOTE FROM ORIGINAL POST
“concerning his Son, who was descended from David according to the flesh and was declared to be the Son of God in power according to the Spirit of holiness by his resurrection from the dead, Jesus Christ our Lord.”
Critically, this passage is best understood to speak of Christ’s grandiose supernatural exaltation in his resurrection. Prior to this event, Jesus frequently called Himself the Son of Man (Mortal with Divine Judgmental Authority or Ultimate Human Being).
While Jesus is God the Son throughout His entire celestial pre-human existence and His incarnated human life, his resurrection assigns him the title “Son of God.” This is the testimony of
Acts 13:32–33 and
Hebrews 5:5–6, as well.
35 The angel answered, “The Holy Spirit will come on you, and the power of the Most High will overshadow you. So the holy one to be born will be called the Son of God.”
