Son
The Bible presents the sonship of Jesus as qualitatively different from other forms of sonship. Humans and angels are called sons of God, but only Jesus is The Son of God—who shared the divine existence [Phil 2:6], essence [Heb 1:3], and glory before the universe began [John 17:5], but then proceeded from The Father [John 8:42], descended to Earth [John 6:38], took on human nature [Phil 2:7a], and tabernacled among humans [John 1:14] in the substance of flesh [Rom 8:3; Phil 2:7c-d; 1 Tim 3:15-16].
Major passages dealing with Jesus's unique sonship include John 1:14-18; 3:13-18; 3:31-36; 5:17-44; 6:37-46; 8:16-58; 10:24-39; 14:6-31; 16:25-31; 17:5; 20:28-31; Hebrews 1:1-14; and 2:5–3:6. The most revealing ascription of The Son is at John 1:18, where He is called μονογενὴς θεός. One translation of this is "The One and Only God," but a compelling case has been made for an optimal translation of "God The Only Son" (Rheaume 2018). This ascription may be shortened to "God The Son," making explicit the implied parallel to "God The Father."
