The ACLU of Massachusetts will always defend the separation of church and state. We also defend the right to hold and express diverse religious beliefs or no religious beliefs at all.

The First Amendment to the U.S. Constitution prohibits the government from establishing a national religion or interfering with the free exercise of religion, with very rare exceptions. Our state constitution offers similar protections.
