No, at least to me, as that would be their understanding of the passage by a strictly literal prophetic approach to the scriptures, so could be a wrong view, but not heretical
See
Post 174. If it's not heresy, then it's not germane to this
op. This thread is not a symposium on Dispensationalism. It's discussion regarding what qualifies as heresy and, more specifically, how is Dispensationalism heretical. This op reports,
"As many probably already know..... Dispensational premillennialism is not typically treated as a heresy, even if it's in opposition to a classical doctrine. That got me wondering: Are there other issues—especially ones that might appear more peripheral to some—that would actually be considered heterodox or even heretical by historic, conservative Christian standards?"
Dispensationalism is not typically treated as heresy in modern futurist circles but outside that arena Dispensationalism is viewed in much different ways, and it has been viewed as contrary to established doctrine since its inception. Even the early Brethren had problems with Darby and, as a consequence
he excommunicated them! 
and formed his own sect
(The Extreme Brethren)! Just imagine someone within the Anglican/Episcopalian, Presbyterian, Methodist, etc. denominations attempting that kind of behavior.
"Y'all aren't part of the pure Church. Y'all are just as corrupt as the rest of Christendom. I'm going to start my own sect and call it the Extreme Presbyterians."
I don't care what sect of Presbyterian he's coming from the PCUSA, PCA, EPC, etc. - NONE of them are going to put up with that dross. That guy is out on his backside and if he tries to (mis)appropriate the Presbyterian label he'll find the General Assembly has filed suit and he'll end up in court.* Dispensationalists
ignored that nonsense and approved of Darbyism.

He has a First Amendment legal right to do so in the US but, ecclesiologically speaking, such behavior is apostate heresy.
