In refuting mistaken ideas, there is the risk of shaking the faith of those who have pinned themselves to particular points of the Law.
These points of contention or contradictions found in scriptures and commentaries become the points of schisms and has led to the worst events in human history and the most warped and twisted understanding of religion.
Trying to unravel the knots of false teachings, without sacrificing those with weak and tenuous faith, is always a major concern. This is because faith itseif, is more important then belief and dogma, even if that faith is entertwined and enmeshed with mistaken ideas.
When the Mahayana Buddhist, Lotus Sutra, focused on the use of “Expedient Means,” by the Buddha, during the expounding of the Sutra to the multitude, 500 haughty Arhats, walked out of the preaching in protest upon hearing that their understanding was based in expedients.
"Thereupon the Buddha addressed Shariputra: “Now in this congregation I am free from [useless] twigs and leaves, and have nothing but all that are purely the true and real. It is good, Shariputra, that such extremely haughty ones as those are gone away. Now carefully listen and I will expound [the matter] for you.” Shariputra said: “So be it, World-honored One; I desire joyfully to listen.”
