Here are the scripture references I had in mind.
The validity of a Buddhist scripture is determined by the spiritual fruits it encourages in its readers:
“As for the qualities of which you may know, ‘These qualities lead to dispassion, not to passion; to being unfettered, not to being fettered; to shedding, not to accumulating; to modesty, not to self-aggrandizement; to contentment, not to discontent; to seclusion, not to entanglement; to aroused persistence, not to laziness; to being unburdensome, not to being burdensome’: You may categorically hold, ‘This is the Dhamma, this is the Vinaya, this is the Teacher’s instruction.’”

The Buddha also discouraged endless and fruitless debates:
Whereas some brahmans and contemplatives, living off food given in faith, are addicted to debates such as these — ‘You understand this doctrine and discipline? I’m the one who understands this doctrine and discipline. How could you understand this doctrine and discipline? You’re practicing wrongly. I’m practicing rightly. I’m being consistent. You’re not. What should be said first you said last. What should be said last you said first. What you took so long to think out has been refuted. Your doctrine has been overthrown. You’re defeated. Go and try to salvage your doctrine; extricate yourself if you can!’ — he abstains from debates such as these. This, too, is part of his virtue.
