Cthulhu cult membership card and cult meeting

[TheHuntsman]

Hello. Played Cthulhu munchkins last night. Everyone but one person was a cultist. The person who wasn't a cultist had the membership card out. This same person played the cult meeting card. Does this make the holder of the membership card an actual cultist in the sense the game is over? Or does it only allow him to come cackle and trade cards? Thanks
