Brown is openly gay. He was an Evangelical Christian in his teens, and became an atheist in his twenties. This is discussed by Brown in the "Messiah" special, and in his book "Tricks of the Mind". An interview as part of Richard Dawkins' two-part documentary series "The Enemies of Reason", where Brown explained various psychological techniques used by purported psychics and spiritual mediums to manipulate their audiences, Brown also said he sought to strengthen his belief and provide answers to common criticisms of religion by reading the Bible and other Christian religious texts. He found none of the answers he sought and came to the conclusion that his belief (in Christianity) had no basis.
