What does the Bible say about the eternal sonship of Christ?

The concept of the eternal sonship of Christ is thoroughly rooted in Scripture, particularly in Psalm 2:7 where God declares, 'Thou art my Son; this day have I begotten thee.' This phrase emphasizes that Christ's sonship is not a moment in time but an eternal relationship between the Father and the Son. Such declarations are echoed in the New Testament, notably in Hebrews 1:5 and Acts 13:33, where the apostles affirm this truth. The doctrine asserts that Jesus is the Son of God in His divine nature, eternally begotten and always existing in this relation without beginning or end, which distinguishes Him from all creation and underlines His divine authority.
