where does it say we have freedom of religion
Freedom of religion in the United States In the United States, freedom of religion is a constitutionally protected right provided in the religion clauses of the First Amendment. Freedom of religion is also closely associated with separation of church and state, a concept advocated by Colonial founders such as Dr. John Clarke, Roger Williams, William Penn and later founding fathers such as James Madison and Thomas Jefferson.[1][2]
First Amendment to the United States Constitution The First Amendment (Amendment I) to the United States Constitution prevents Congress from making any law respecting an establishment of religion, prohibiting the free exercise of religion, or abridging the freedom of speech, the freedom of the press, the right to peaceably assemble, or to petition for a governmental redress of grievances. It was adopted on December 15, 1791, as one of the ten amendments that constitute the Bill of Rights.
