Introduction to the Hebrews

The purpose of [the] author’s exegesis of Old Testament scripture… is to establish the finality of the gospel by contrast with all that went before it (more particularly, by contrast with the Levitical cultus), as the way of perfection, the way which alone leads men to God without any barrier or interruption of access. He establishes the finality of Christianity by establishing the supremacy of Christ, in his person and in his work.

—F.F. Bruce
