In the United States, atheism is protected under the First Amendment’s Free Exercise Clause. In August 2005, in a case where a prison inmate was blocked by prison officials from creating an inmate group to study and discuss atheism, the court ruled this violated the inmate’s rights under the First Amendment’s Free Exercise Clause. The United States Court of Appeals for the Seventh Circuit affirmed previous Supreme Court precedent by ruling atheism be afforded equal protection with religions under the 1st amendment.
There are also on-line churches that have been created by atheists to secure legal rights, to ordain atheist clergy to hold ceremonies, as well as for parody, education, and advocacy.
Although Theistic Satanism believes in deities, LaVeyan Satanism does not believe that Satan is a god; rather the function of God is performed and “Satanism begins with atheism,” satisfied by the satanist him/herself. said Church of Satan High Priest Peter H. Gilmore in an interview. “We begin with the universe and say, ‘It’s indifferent. There’s no God, there’s no Devil. No one cares!'” The needs of worship, ritual, and religious/spiritual focus are directed, effectively, inwards towards the satanist, as opposed to outwards, towards God. It follows that Satanism shuns the idea of belief in all other deities as well, including, to the surprise of many, Satan. It rejects outright concepts such as prayer, the after-life, and divine forces and is therefore atheist per se.
There are some organizations falling between these two extremes. The First Church of Satan, formed as an offshoot to LaVeyan Satanism and makes no claims about the personification of Satan. Individual members are left to decide for themselves whether Satan is real, fictional, or conceptual.
