You didn’t answer my question, so I’ll rephrase it.
Do you believe that any piece of written text can be understood at a level sufficient to capture the intended meaning and act on it properly?
There is no use in talking about “infallibility” until we can come to a consensus on that question.
I don’t really know, but I don’t believe so. I’m sure there is some stuff that has been written that no one can understand, but I suppose at a minimum, the originator should be capable of that.
