What does the First Amendment signify regarding church and state?

The First Amendment of the United States Constitution plays a critical role in defining the relationship between government and religion. Its establishment clause specifically prohibits the government from establishing an official religion or favoring one religion over another. This principle is fundamental to ensuring a separation between church and state, promoting religious freedom by allowing individuals to practice any religion—or none at all—without interference or endorsement from the government.

This clause is interpreted to mean that the government cannot pass laws that would advance or inhibit religious practice, thereby upholding the independence of religious institutions from government influence. It encapsulates the idea that the government should remain neutral on religious matters, allowing diverse beliefs to coexist peacefully within society.
