Wouldn't you agree, though, that it's a matter of debate and interpretation as to whether a belief in the Buddha's omniscience is required for Right View? Because I don't see this included in the sutta expositions of either mundane or transmundane Right View. To say that it can be found somewhere in the teachings is one thing, to regard it as a core belief is another.
Well, as I said above, perfect saddha in Buddha is included in complete factor of Right Views. And Buddha's omniscience is mentioned in different suttas as a quality of the Buddha. So it is natural that you have this belief, this confidence, that Buddha is such, if you really trust him. That is a belief that he had infinite possibility to understand anything in the world that he wants, and because of that he can't make any mistake in any question he is speaking about. If you think that Buddha can make a mistake, then you don't have perfect saddha in him and in his Dhamma. You still ponder that may be he speak something that he doesn't understand or know. You still don't trust him, no matter what is the topic. And in this case this is not a perfect saddha and First Factor of the Path is not full, you still hesitate.
Wasn't the Visuddhimmaga written some eight centuries after the Buddha's parinibbana?
Yes, but it wasn't Buddhagosa's personal opinion (at least not in everything). What he did is structured ancient commentaries. How ancient they were, no one knows.
Have you personally ever come across a statement or claim in the scriptures which you find it difficult to accept as factual or literally true?
Yes, there were a couple of "strange" points for me about devatas. But since I generally do believe that they exist, I finally accepted it. At the present moment I have read a lot of suttas (almost everything avaliable in english), translated many into my native language, and I agree with everything that I find in them, including such "unpopular" topics as cosmology discriptions, literal hell sufferings and the stuff -) (making allowance for those cosmology explanations were understandable in that place and time). Am I wrong accepting all that? Well, time will show, but this belief is a part of my practice. And that is a part of practice as seen for example from Gilana sutta
where dying householder Citta instructs his relatives:- "Then, master, instruct us, too."
- "Then you should train yourselves: 'We will be endowed with verified confidence (saddha) in the Buddha: "Indeed, the Blessed One [the Buddha] is worthy & rightly self-awakened, consummate in knowledge & conduct, well-gone, an expert with regard to the cosmos, unexcelled as a trainer for those people fit to be tamed, the Teacher of divine & human beings, awakened, blessed." "'We will be endowed with verified confidence in the Dhamma: "The Dhamma is well-expounded by the Blessed One, to be seen here & now, timeless, inviting verification, pertinent, to be realized by the wise for themselves."
or Mahanama sutta
:"Have no fear, Mahanama! Have no fear! Your death will not be a bad one, your demise will not be bad. If one's mind has long been nurtured with conviction (saddha), nurtured with virtue, nurtured with learning, nurtured with relinquishment, nurtured with discernment, then when the body — endowed with form, composed of the four primary elements, born from mother & father, nourished with rice & porridge, subject to inconstancy, rubbing, pressing, dissolution, & dispersion — is eaten by crows, vultures, hawks, dogs, hyenas, or all sorts of creatures, nevertheless the mind — long nurtured with conviction, nurtured with virtue, learning, relinquishment, & discernment — rises upward and separates out.
