dan, it looks like you're just going in circles. (arguments that have no end in sight and no good and true direction between more than one party).
per other: when paul used what a pagan had said, he did so by revelation/wisdom/purpose/training from yahshua, (not ever as if anything of the flesh / pagan beliefs/ poets/ socialites/ scholars or lawyers ever produced anything good) ...
perhaps like when yahshua , who spoke only what his father spoke (never anything on his own),
used the pharisees or saducees own beliefs to discredit them/ against their error (with a hope to correct them or others?) or otherwise and always for yahweh's purpose
and never, never, never giving any glory nor credit to social worldly mankind or the flesh or the carnal etc...
