Sadly you are duped to the point of not even knowing the history of dispensationalism. It had it's beginning in 1830 with a vision by a Roman Catholic girl named Margaret McDonald in Glascow, Scotland and was run with by John Nelson Darby, and later Scofield in the US.
What "dogma" is that. I said nothing about "dogma". Sadly, you didn't even get the meaning of what was said, which is, your false system of dispensationalism had it's beginning with a vision by a Roman Catholic girl and John Nelson Darby in Scotland in 1830. It's a johnny-come-lately system, and hasn't been around for "centuries" as you presume.
I bet you think John Hagee is a wonderful teacher too, don't you?
