All Christians
Depends on whose doctrines/dogmas and what religious cult or philosophical bent one adheres to. Most of the current school and college educators maintain none worthy of mentionat all. Totally absent from historical notes in school texts.
IIRC, Thomas Paine’s was not, and he said so..
He said he believed in God, but rejected Christianity, so I’d say he was not a Christian. Satan believes in God but isn’t a Christian.
