The first video is an overview covering a number of topics. Historicism overlaps with Preterism at several places, so when he mentions “Reformers” that is code for “Historicism”. Hebrew Roots has a different view of the New Covenant and how Israel is redeemed, The Godhead, Soteriology, and Old Testament authority.
The Berean Bible Church doesn’t know about the hoax called Holocaust, but doesn’t affect the lecture. They think God is “everywhere at once”, and Temple is inside of people rather than a physical place in the New Jerusalem. They use occult terms like “Shekinah glory”. Although their theology is quite off base, they do understand about Zionism, who modern Jews are, and the series shares very important information that is difficult to get from the Neo-Zionists or Judeo-Christian cults.
This series is rather fast paced and assumes you already have a basic understanding of Preterism eschatology and some basic Bible history and Church History.
