Cthulhu cult membership card and cult meeting

[TheHuntsman]

Does this mean a person with cult membership card can equip cultist only items? This didn't answer my question if the cult meeting with the verbiage " any non-cultist with a cultist card can now play it and Join the cult" it was my understanding that a cult membership card doesn't work as far as giving a lvl or ending the game. But does the words "join the cult" actually turn them into a cultist that can allow them to end the game? Thanks
