(God) hath in these last days spoken unto us by His Son, whom He hath appointed heir of all things, by whom also He made the worlds (Hebrews 1:2).
The unique divine Sonship of Jesus Christ is emphasized here in Hebrews 1. The above text, for example, introduces the Son as the Creator, then as the revealing Word, and finally, as the appointed heir of all things.
This chapter also demonstrates that Gods Son was recognized even in the Old Testament. Verse 5 quotes Psalm 2:7: Thou art my son; this day have I begotten Thee, and I Chronicles 17:13: I will be His Father, and He shall be my son. That this Son is none other than God Himself is confirmed in verse 8, quoting Psalm 45:6: Thy throne, O God, is for ever and ever. That He is the Creator is asserted in verse 10, referring to Psalm 102:25: Of old hast thou laid the foundation of the earth. That He is now at Gods own throne is stressed in verse 13, citing Psalm 110:1, Sit thou at my right hand, and to be worshipped as God, in verse 6, taken from Psalm 97:7: Let all the angels of God worship Him.
Furthermore, Hebrews 1 notes a manifold description of the meaning of the divine Sonship. He is Son of God by eternal generation, as the brightness (or out-radiating) of His glory, and the express image of His person (v.3). He is Son of God by miraculous conception (v.5), above, quoted in Acts 13:33 (note Romans 1:4) as referring to His Sonship by bodily resurrection. Verse 6 refers to the divine proclamation of the Sonship (also Matthew 3:17; 17:5). Verses 8 and 9 stress the testimony of His uniquely holy nature. Thou hast loved righteousness, and hated iniquity. Finally, as the Son, He is promised universal inheritance from His Father (vs.2,13). From eternity to eternity, Jesus Christ is Gods only-begotten Son! And yet God gave His only begotten Son that we might have everlasting life! (John 3:16). HMM
