“Any degree of Preterism is blasphemous unBiblical nonsense from hell, imho”
No, not really. Every Christian agrees SOME prophecies have been fulfilled. Technically that makes us all “partial preterists” to some degree or another. If you believe the OT prophecies of the Messiah were fulfilled in Jesus, then you are a “preterist” as concerns those prophecies.
We just normally reserve the term for those people who believe prophecies are fulfilled that most other Christians don’t believe have been fulfilled.
And in regards to dispensationalism...
Every christian is dispensational.
Do you believe we are in the Garden of Eden?
Do you believe we are part of the historical nation of Israel?
Do you believe we are now in heaven?
If you do not, you recognize God’s history is divided into dispensations.
