The United States Constitution established freedom of religion in America in 1791. The right is guaranteed in the First Amendment, along with freedom of the press and freedom of expression. Specifically, it says “Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof.” Even though 60% of Americans currently oppose an Islamic Cultural Center near the World Trade Center site, freedom of religion is what makes America different from many other countries. If we deny some people the right to worship the way they please, then the nature of our society will change and none of us will truly be free again.

But let me be clear. As a citizen, and as President, I believe that Muslims have the same right to practice their religion as everyone else in this country. And that includes the right to build a place of worship and a community center on private property in Lower Manhattan, in accordance with local laws and ordinances. This is America. And our commitment to religious freedom must be unshakeable. The principle that people of all faiths are welcome in this country and that they will not be treated differently by their government is essential to who we are.
