Every reader of Heb expects that in the first chapter will be explained to him what has been announced in the first propositio of this writing, i.e. the Name of Christ is superior over the angels (1:4). In fact the author in 1:5-14 presented only the first part of this Name when he focused on Christ?s relation to God.
And because only God knows Jesus Christ in his mystery fully, the author accepted role of simple ?redactor? of divines oracles found in OT. Christ as the ?Son of God the First-born?, participating on divine power of the God-Creator, being himself ?God? and ?the Lord?, is contemplated in the light of the divine language of the Scriptures, inspired by the Spirit of God.
