I want to know the answer to the following question:
What group popularized early Protestant teachings about separation of church and state?
All the background I'm provided with is that "These Lockean ideas were fundamental to the United States Declaration of Independence, which also deduced human rights from the biblical belief in creation: "We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty, and the pursuit of Happiness."". Is that enough to answer the question?
Answer: no
