Fundamentalism came to differing parts of the North American Mennonite world at different times. But for all it was a way of responding to the groups changed relationship to the dominant culture.

It was significantly a cultural movement because the theological modernism in the Mennonite world was only incipient and marginal. Cultural Fundamentalism was a way to codify doctrine, reassert churchly authority and redefine cultural boundaries.
