One of those “Salvation Cults” owned that ferry that sank in South Korea, the head of the cult was the subject of a manhunt until they found his body, but several of his family are in prison now.
Their cult basically said you can sin all you want after you are saved, because once saved always saved.
This sounds terribly close to the "Mad Monk" Rasputin who believed that you had to sin in order to be forgiven --- so, sin away.
