Therefore, holy brethren, partakers of the heavenly calling, consider the Apostle and High Priest of our profession, Christ Jesus[.]
This last clause can almost be taken as the theme of the Book of Hebrews—
Consider Christ. Because that is what we are asked to do nearly from the get-go in this epistle. From chapter 1, chapter 2, chapter 3, and beyond, we are asked to think about Jesus Christ—to consider him.
In this sense, the Book of Hebrews is probably one of the most important books in the Bible for establishing our Christology—that is, our theology of Christ: who he is, what he is, where he fits in the overall picture of God’s plan. Between the Gospel of John and Hebrews you can form a very highly-developed Christology and understanding of Jesus.
Paul (who I believe to be the writer of Hebrews) tackles this from a variety of angles. Let’s take a look at some of them, beginning in chapter three.
