Dr. James Spencer welcomes Gregory R. Lanier (RTS Orlando, NT) and William A. Ross (RTS Charlotte, OT), co-editors of The Authority of the Septuagint: Biblical, Historical & Theological Approaches (IVP Academic). What is the Septuagint (LXX)? Why is it a library of Greek translations rather than one book? How did NT authors access Scripture—and why do their citations sometimes match Greek more than Hebrew? We unpack a three-fold framework for authority (normative Hebrew text, derived authority of translations, interpretive value of the LXX), the translation spectrum within the LXX, patristic and Reformation debates, Dead Sea Scrolls, and why Hebrews relies so much on the LXX. Plus: practical study tips and which English LXX to use. Book link and IVP 20% discount code in the show notes.

Meet Your Host

James Spencer earned his Ph.D. in Theological Studies from Trinity Evangelical Divinity School. He believes discipleship will open up opportunities beyond anything God’s people could accomplish through their own wit and wisdom. As such, James seeks to help believers think Christianly about social, cultural, and political assumptions. His desire is to see Christians test God by trusting God so that they conform ever more closely to the image of Christ.

In addition to being a regular contributor to Christianity.com and Washingtontimes.com, James has published multiple works, including Christian Resistance: Learnign to Defy the World and Follow Christ, Useful to God: Eight Lessons from the Life of D.L. Moody, Thinking Christian: Essays on Testimony, Accountability, and the Christian Mind, and Trajectories: A Gospel-Centered Introduction to Old Testament Theology.

James currently serves as president of the D. L. Moody Center, an adjunct instructor at Wheaton College Graduate School, and faculty member at Right On Mission.
