From the Greek adiaphoros, meaning "making no difference, inconsequential," an adiaphorist
was a pragmatic Reformer who believed that certain practices condemned by Luther--such as the vestments worn by clergy in church--were irrelevant.
It is refreshing to be told of the "moderation and pragmatism" of the Zurich tradition (24), and Euler makes an intriguing case for Zwingli's and Bullinger's writings as a possible source for the adiaphorist
tradition in English Protestant theology.
Papists, Interimists, and Adiaphorists
saw history, legends, or arguments from history or tradition as equal if not superior to the authority of the Bible.
