wrong.
1. The Bible is not merely "disseminated by word of mouth over centuries".
2. Secondly the weight of textual evidence begs to differ. There is a solid case for preservation of the texts of both the Old Testament and New Testament, while that does not prove the truthfulness of the text, it does a least put a pin on the whole, inconsistency idea, because we are fairly sure what the original would have been, by the sheer number of manuscripts (regarding the variations of the text [New Testament], it is interesting the critics never mention what those variations are (things like spelling/dialect variants, some which are not even noticeable upon translation into English, or clarifications). , the variety of languages and locations; especially when compared to other texts of antiquity. (that was the first point I made in the post you quoted from)
One of the strengths of being convinced of the veracity of the Bible (say over the Quran), is its diverse authorship and genre styles; set over 1500 years; written in different historical and political contexts (yes the underlying culture, especially religious culture is consistent but even that evolves). Of course books written earlier can be referenced by those that come latter and its understandable that authors would develop similar themes further. However, the sheer weight of intertextuality is what I am referring to. Allusions, links, symbolism. Again it does not prove that veracity of it, but it does show the integrity of group of texts as a whole (aka its internal correspondence)
