Soka Gakkai members are guilty of the twenty cardinal sins

"Next, they have abandoned their father, Shakyamuni Buddha, and hence stand accused of the five cardinal sins. How can they escape falling into the hell of incessant suffering? And finally, they have turned their backs on their teacher, Shakyamuni Buddha, and thus are to be numbered among those who commit the seven cardinal sins. How could they fail to sink into the evil paths of existence?

Shakyamuni Buddha, the lord of teachings, as we have already seen, possesses the three virtues of sovereign, teacher, and parent in relation to the living beings of this sahā world. He is the Buddha to whom they are greatly indebted. Anyone who would abandon such a Buddha and put faith in the Buddha of some other realm, honoring and relying upon Amida or Medicine Master or Mahāvairochana*, is guilty of committing the twenty cardinal sins and hence will surely fall into the evil paths of existence."
