Montanist

Been reading a bit about Justinian I and Theodora I. (483-565), and came across this quote.

"he prosecuted the heretical Montanists"

I have read a bit out the Montanists, although right now I can't remember their specific heresy (something to do with the divinity of Christ, I think).

Anyway, my real question. Is a Montanist (the heretic) pronounced the same way that a fan of Montana would be?

I see my self as a strong Montan(a)ist, and would maybe go so far as to say that I promote Montan(a)ism. Poor Justinian, if he only knew that we'd still be promoting such things 1500 years later...
