Hi, the problem though is that the Theras are saying that abhidhamma is Buddhavaccana, so your above view equals to what Sarvastivadins were saying at the time, and Theravadins refuting.TheDhamma wrote: Or you could hold the Abhidhamma to be of immense value and authentic words of the Theras, but not necessarily see it as Buddhavacana. It was certainly composed and written by Theras, but that does not necessarily make it the exact words of Buddha. They can even be considered highly beneficial and important, but Buddhavacana is another matter.
From the CMA quote:
Best wishesTheravada orthodoxy thus maintains that the Abhidhamma Pitaka is authentic Word of the Buddha, in this respect differing from an early rival school, the Sarvastivadins. This school also had an Abhidhamma Pitaka consisting of seven books, considerably different in detail from the Theravada treatises. According to the Sarvastivadins, the books of the Abhidhamma Pitaka were composed by Buddhist disciples, several being attributed to authors who appeared generations after the Buddha. The Theravada school, however, holds that the Blessed One himself expounded the books of the Abhidhamma, except for the detailed refutation of deviant views in the Kathavatthu, which was the work of the Elder Moggaliputta Tissa during the reign of Emperor Asoka.
