“Has the Church Replaced Israel?” A live debate between Calvin Smith and Stephen Sizer broadcast on Revelation TV 9th November 2011.
This 1h 30m debate is well worth a watch if you are interested in Israelology and Christian Zionism (small PDF).
Stephen Sizer has published a number of books dealing with this subject, and turned his PhD thesis into a book titled “Christian Zionism”.
Calvin Smith is the principal of King’s Evangelical Divinity School (UK).
Sizer’s polemical writings are offensive to many Christians (myself included), and Smith did well to highlight and condemn Sizer’s labeling of Christian Zionism as “deviant heresy” and “another gospel” (around 1:06 in the debate).
