Nichiren on the Soka Gakkai slanderous teaching of Interfaith

"It is said that good medicine tastes bitter. This sutra, which is like good medicine, dispels attachments to the five vehicles and establishes the one ultimate principle. It reproaches those in the ranks of ordinary beings and censures those in the ranks of sagehood, denies [provisional] Mahayana and refutes Hinayana. It speaks of the heavenly devils as poisonous insects and calls non-Buddhists demons. It censures those who cling to Hinayana teachings, calling them mean and impoverished, and it dismisses bodhisattvas as beginners in learning. For this reason, heavenly devils hate to listen to it, non-Buddhists find their ears offended, persons of the two vehicles are dumbfounded, and bodhisattvas flee in terror. That is why all these types of people try to make hindrances [for a practitioner of the Lotus Sutra]. The Buddha was not speaking nonsense when he declared that hatred and jealousy would abound.” -- The Opening of the Eyes
