The First Amendment commands government to have no interest in theology or ritual; it admonishes the government to be interested in allowing religious freedom to flourish -- whether the result is to produce Catholics, Jews, or Protestants, or to turn the people toward the path of Buddha, or to end in a predominantly Moslem nation, or to produce in the long run atheists or agnostics. On matters of this kind, government must remain neutral. This freedom plainly includes freedom from religion with the right to believe, speak, write, publish and advocate antireligious programs.
