Roy Wallis

Roy Wallis (1945–1990) was a sociologist and Dean of the Faculty of Economics and Social Sciences at the Queen's University Belfast. He is mostly known for his creation of the seven signs that differentiate a religious congregation from a sectarian church, which he created while researching the Church of Scientology. He introduced the distinction between ''world-affirming'' and ''world-rejecting'' new religious movements.

After publishing his book ''The Road to Total Freedom'' (1976), an analysis of the sociology of Scientology, he was harassed by the church both legally and personally. Forged letters, apparently from Wallis, were sent to his colleagues. Provided by Wikipedia
