Scripture: One Book at a Time
The whole of Sacred Scripture is a single narrative that promises and points to Jesus Christ as Lord and Savior of the World. It is an epic story, the greatest ever told, and told "one book at a time." Each book makes it contribution to the narrative as God reveals God's self to us and his desire that all be saved.

Lesson 69 – Hebrews
There is a joke among scripture scholars about St. Paul’s Letter to the Hebrews: it is not from St. Paul, it is not a letter, and it may or may not be to the Hebrews and even then it is not clear who the “Hebrews” exactly are. There is a lot about this book of Scripture that is still the topic of scholarly debate. That includes the geographical location of the intended recipients. If you’d like to delve into the debate, there are plenty of online sources, including the introduction provided by the US Catholic Bishops. A solidly Catholic commentary is provided at Catholic Culture and was written by Fr. William Most.
What we do know that Hebrews is written to a community under persecution some of whom are waivering in their faith to the nascent Christian religion and seem to be considering returning to Judaism, a faith tradition free from persecution in the Roman Empire. The recipients of the letter clearly have a strong background in the Hebrew Scriptures as the book is replete with OT references. And it is through these references that the author makes the case that Jesus is greater than all things and is the fulfillment of the promises of God – so anchor your faith and hope in Jesus!
