Final answer:
Puritans aimed to reform the Church of England, while separatists wanted to dissolve all ties and create their own congregation, making Option 1 the correct answer.
Step-by-step explanation:
Puritans differed from separatists in that Puritans sought to reform the Church of England from within rather than separating from it entirely. The Puritans who settled Massachusetts Bay aspired to purify the Church of what they saw as lingering Catholic elements and set a godly example for the church to follow. On the other hand, the Pilgrims (a group within the separatists) who settled Plymouth were convinced the Church was beyond reform and thus established their own congregation completely separate from it.
The correct answer to your question is that Puritans, unlike separatists, wanted to purify the Church of England, rather than completely separate from it. Therefore, the correct option, considering the historical context, is Option 1: Puritans wanted to purify the Church of England, separatists wanted to separate from it entirely.
