Yes. That is correct.
P.S. The Buddha set an excellent example with how he dealt with Devdatta. As we know, Devadatta remained a bhikkhu until his death. Even after he tried to take the life of the Buddha (and injured him), the Buddha did not even expel Devadatta.
– There is no point in getting into emotional “battles” with those with different views.
– But, one should not hesitate to point out any discrepancies in the opposing arguments with evidence from the Tipitaka. It is up to them to examine the evidence presented and decide.
– Once, Devadatta took 500 bhikkhus and left the Buddha. The Buddha sent Ven. Sariputta and Ven. Moggalana to advise those bhikkhus. They were able to bring those bhikkhus back.
