Reformation: This was a religious movement in the 16th century that led to the creation of Protestant churches. It's like when students start questioning school rules leading to changes (new denominations).
Episcopal System: This is a form of church governance which is hierarchical in structure with the chief authority over a local Christian church resting in bishops. It’s similar to having class representatives (bishops) who have authority over their respective classes (local churches).
Puritans: These were English Protestants in the 16th and 17th centuries who sought to purify the Church of England from its Catholic practices. They're like a group of students who want even more changes to the school rules.
