So when did this idea that a scripture or a prophet or a messenger or a pope is absolutely perfect in every way come into practice? Has it been there since early times, or is it more recent? What purpose does it serve?
What or who do you consider infallible, if anything?
As an eastern thinker and logical person, I don't get infallibility. To be clear, I understand what it means, I just don't get how anyone else could believe in it, yet I know some do. I just shake my head and go 'really?'
Here's an example. "I'm infallible. I said I was infallible, and since I'm infallible, it is only logical to conclude I'm infallible. I mean, how could an infallible person claiming to be infallible possibly be wrong?"
Does this sound logical to you?
Well. At least from Shankara’s teaching, if perception contradicts scripture, the latter is to be understood to be correct. Else, of what value is scripture, if ego-intellect-sense could arrive at truth of their own source? In fact, scripture pointedly says “Mind and Word return from it”.
I do not know whether what I have written is relevant to the OP?
