I guess my experience around Nazarenes must have been limited to those on the fundamentalist end of the scale. There is a Nazarene university in Bethany OK, a suburb of Oklahoma City, where Hobby Lobby is based. That suburb has a history of being run by the college/university, including no liquor stores being allowed for many years.
Mine was too, ironically, until I moved to Oklahoma. Growing up in Arkansas the joke was always, "Why don't Nazarenes have sex standing up? Because someone might think they were dancing." (Told to be by a Nazarene by the way.) These days I can say that some of my best friends are Nazarenes, and while they are not from the far-left like Schmitz, they are certainly not legalists either.
