A type of Christian who pays less respect (however minimal or marginal) to non-church-goers. Note now the hyprocrisy that a Churchist does not necessarily have to go to church themselves - but will always say "I'd go if I had the time" in order to deter the whiplash effect of their bias.
The belief in Churchism.
"It's Churchists like him that give religion a bad name."
"I used to be a Churchist."
