Step-by-step explanation:
The group recognized for its rigid religious beliefs, solid work ethic, and desire to purge the Church of England of immoral practices were the Puritans. These English reformers, known for their insistence on "purifying" the Church of what they perceived to be unscriptural and particularly Catholic elements, followed the teachings of John Calvin.
