Similar in use to "Fundie" of those who hold to the fundamental elements of the faith, but who are portrayed as fanatics or ignorant by the more "enlightened."
"method of biblical interpretation"? You're taking that as established, which is far from being the case.
We might add "Calvinist" for all who believe in the doctrines of Grace, or believers in "Displacement theology" for those who do not see a special place for the ethnic nation Israel in eschatology
