Heidegger's Bible Handbook: Hebrews: Argument of the Epistle
7. The Argument of the Epistle.
Therefore, thus Saint Paul in this Epistles establishes the weaker Jews, who were ζηλωταὶ τοῦ νόμου, zealous for the law, Acts 21:20, in the doctrine of the Gospel, and demonstrates that Jesus Christ is true God and true man; the great Prophet, whose doctrine it is sin to despise; and the true and only Priest and everlasting sacrifice, in such a way that for expiation and cleansing no Aaronic or Sacerdotal sacrifices are needful, and nothing is wanting for absolute justification to one that possesses Christ in faith: he asserts that all the Saints of the Old Testament pleased God by faith, and served Him in patience, love, and innocence of life; and, finally, he sets forth useful and salutary instructions for life. And thus he excites the Hebrews to a firm, sincere, and fruitful faith in Christ, to union with believers bearing the cross of Christ, and to the abandoning of useless servitude; comfirms them against the blasphemies and persecutions of their own people; and removes the great suspicion conceived concerning him. Finally, this Epistle is a kind of commentary on that word of God the Father heard from heaven on more than one occasion: This is my beloved Son, in whom I am well pleased: Hear ye him, Isaiah 42:1; Matthew 3:17; 12:18; 17:5.
