What is the primary focus of the establishment clause?

The primary focus of the establishment clause is to prevent the government from establishing an official religion. This clause is found in the First Amendment of the U.S. Constitution and seeks to ensure that the government remains neutral regarding religious matters, allowing for the free exercise of religion without governmental interference or favoritism.

This neutral stance safeguards against any one religion being endorsed or supported by the government, which helps maintain a pluralistic society where diverse beliefs can coexist. While the promotion of the separation of church and state is a related concept, it is essentially rooted in the establishment clause's core purpose to prevent any governmental endorsement of religion.
