<span>The Enlightenment challenged the traditional authority of the church. During the Scientific Revolution, empirical research and observation was put forth as the path to finding truths about nature and the universe. Astronomers such as Nicolaus Copernicus, Johannes Kepler, and Galileo Galilei were religious men, but they encountered much resistance from the established church because their ideas challenged the church's teaching that the Earth was the center of the universe. The Enlightenment went even further than the Scientific Revolution had gone in challenging the traditions and authority of the church. A number of Enlightenment thinkers were Deists -- belieiving God created the universe but let it run from there on natural principles He created. Some Enlightenment proponents, such as David Hume and Denis Diderot, even went as far as agnosticism (Hume) or atheism (Diderot). </span>
Answer:
Assuring that the harms of the British Government wouldn't be repeated
Explanation:
I assume you mean the American Revolution by back then, and the reason that freedom of religion was so important (as well as many other Bill of Rights amendments) was to assure that the harms of the British Government (detailed in the Declaration of Independence) could not be repeated. Many people fled to America to escape the religious oppression of the Church of England, as it was both very strict on what religions were allowed and very closely entangled with the British Government, hence the separation of church and state in America.
It is true because if this age never occurred they would have never made the bill of rights. The reason behind this was because they dethroned a king and it heled them notice they needed laws!
The Supreme Court decisions in Griswold v. Connecticut and Roe v. Wade were based on the principle of the right to free speech.
