About
After 25 years as professor of New Testament at Wheaton College and Graduate School, Gary joined the seminary faculty in 2017. He became Dean of the Faculty in 2019 and retired from full-time service in 2023. Today he is an adjunct professor working with ThM and PhD students.
Gary’s interests center on the gospels (particularly the Gospel of John), the historical Jesus, and the contextual and cultural background of the first century Judea as a framework for interpretation. He has also taught graduate seminars on the integration of psychology and theology as well as the integration of theology and the politics of the Middle East. He is ordained in the Presbyterian Church U.S.A. and is a frequent speaker at conferences, retreats and churches. He often leads pastors’ workshops on teaching the New Testament and faculty development workshops at colleges and seminaries based on his book, Mapping Your Academic Career.
He is deeply invested in the Middle East and its Arabic-speaking churches from Iraq to Egypt and travels there frequently. He has organized pastors’ conferences, taught at seminaries, and been a conference speaker in the Middle East. He is often called on to interpret the Israel-Palestine conflict at American churches and church settings.
