Final answer:
Roger Williams advocated for religious freedom and founded Rhode Island. Thomas Jefferson drafted the Virginia Statute of Religious Freedom. George Washington warned about the dangers of political parties, and John Locke believed in consent of the governed for legitimate government.
Step-by-step explanation:
The early colonial leader who advocated for religious freedom is Roger Williams. He was a proponent of separation of church and state and founded the Rhode Island colony based on principles of complete religious tolerance. Additionally, the Virginia Statute of Religious Freedom was drafted by Thomas Jefferson. This statute is a significant precursor to the First Amendment protections of religious freedom in the United States Constitution. As for the founders and colonies, William Brewster is incorrectly paired with New Haven; he was associated with the Plymouth colony. Lastly, the supporter of federalism who warned against the dangers of political parties was George Washington, and the philosopher who argued that government should exist only with the consent of the governed, based on the natural freedom of people, was John Locke.
