Historic Context
Why the First Amendment Was Written
The Pilgrims and others fled to the New World to escape religious persecution from the government of England. England had a State Church.
Before the Constitution was ratified, most of the Colonies had their own official churches, and they followed the practices of the British government – persecuting people who dared to organize or be involved in an unapproved church.
Therefore, the issue of the day was, Should the Government be in the Religion Business? And if so, which denomination should become the “official” church?
The First Amendment addressed this issue. “Congress shall make no law respecting an establishment of religion . . .” Do you get that? It’s very easy to understand. The Government cannot make a law concerning a person's religion:
What it does not say:
The wording of the First Amendment begins with, "Congress whal make no law..."
The purpose of the First Amendment was not to keep churches out of the Government. It was to keep the Government out of the churches.
