Bridging the Testaments Video Lectures surveys the history and theological developments of four significant eras in Israel's postexilic history: The Persian Era (539-331 BC), the Hellenistic Era (331-167 BC), the Hasmonean Era (167-63 BC), and the Roman Era (63-4 BC). In doing so, Athas does away with the notion that there were four hundred years of prophetic silence before Jesus and demonstrates how the Old Testament period continued right up to the time of Jesus.

The videos outline the political and social developments of these four periods, with particular focus on their impact upon Judeans and Samaritans, and how these contributed to revelation and theological formation. Using a wide range of biblical and extrabiblical sources, George Athas reconstructs what can be known about the history of Judea and Samaria in these eras, providing the framework for understanding the history of God's covenant people, and the theological developments that occurred at the end of the Old Testament period, leading into the New Testament. Finally, an epilogue sketches the historical and theological situation prevailing at the death of Herod in 4 BC, providing important context for the New Testament writings.

In this way, Bridging the Testaments Video Lectures bridges the Old and New Testaments by providing a historical and theological understanding of the five centuries leading up to the birth of Jesus. The videos track a developing biblical theology through this period and abolishes the notion of a four-century prophetic silence.
