Jonathan Rowlands, a theology lecturer, discusses the book of Hebrews and its themes. He explains that Hebrews is a unique text in the New Testament, and its genre and authorship are still debated. The book emphasizes Jesus as a high priest and his role in atonement. Rowlands explores different readings of Hebrews 1:3b and how they impact the understanding of the text. He also discusses the importance of Jesus' pre-crucifixion life in the overall message of Hebrews. In this conversation, Jonathan Rowlands discusses his research on the book of Hebrews and the sacrificial system. He explains that the sacrifice Jesus offers in the heavenly temple is not his death on the cross, but the totality of his obedient life. The author of Hebrews is primarily concerned with what Jesus is doing now, present tense, as a high priest. There are glimpses of a broader renewal of all things, including heaven and earth, in the book. Rowlands recommends reading the works of David Moffat and Matthew Thiessen for further insights into Hebrews and biblical studies.
