These sūtras were not recognized as being Buddha word by various early Buddhist schools and there was lively debate over their authenticity throughout the Buddhist world. Various Mahāyāna sūtras warn against the charge that they are not word of the Buddha, showing that they are aware of this claim. Buddhist communities such as the Mahāsāṃghika school were divided along these doctrinal lines into sub-schools which accepted or did not accept these texts. The Theravāda school of Sri Lanka also was split on the issue during the medieval period. The Mahavihara sub-sect rejected these texts and the (now extinct) Abhayagiri sect accepted them. Theravāda commentaries mention these texts (which they call "Vedalla/Vetulla") as not being the Buddha word and being counterfeit scriptures. Modern Theravāda generally does not accept these texts as "buddhavacana" (word of the Buddha).
