I'm not going to take up the mantle of textual analysis,
And I'm not the guy you want to talk to if the discussion is centered around Xian Scholasticism.
No idea what you are talking about, to be honest. When did Textual Analysis get a mantle, and what have the Xians have to do with this?
Bio of the Buddha was nowhere near my introduction to the Dhamma. Has a value, of course. But I just can't envision a scenario in which smart people who might become Buddhists are first turned on because he was a prince, he was born like this or like that, at such and such a time, etc. And adding all the ridiculous mythical fantasies renders whatever value this approach may have irrelevant, at best.
Surely there is a better way to introduce Buddhism to a wide audience.
