The core teaching of the prewrath position that the church would face the Antichrist before the day of the Lord’s wrath is not new. In fact, every early church father who wrote on this topic believed this. What is new is some of the refinements of eschatology that were articulated by Marvin Rosenthal and Van Kampen back in the late 80s and early 90s, and continues to be developed with more biblical insights up to this day.
Incidentally, I would hope that no Christian would object to the idea that the Holy Spirit is still active teaching the church to understand God’s Word more deeply and anew on important truths!
