God is righteous. In order to justifydivine any act as righteousness, one has to step out of oneself and weigh the act using criteria established by a Total Other: God.
Revelation establishes God’s criteria. The revelation itself cannot be questioned, especially when it comes as a Book. The Book is what it is.
On the other hand, the interpretation of the Book can be questioned. For example, Moderns interpret the Bible as “myth” (“fable”, “conjured” and so on). One cannot prove or disprove this interpretation, or any interpretation, for that matter. One can, however, find consensus.
Each consensus-interpretation constitutes an element in a symbolic order that, in turn, supports particular social constructions.
The Modern consensus that “the Bible is myth” undermines the social constructions of Christianity and overmines the social constructions of various alternate cults, especially the Public Cult of Progressivism and the private cults of New Age and Satanic Magic.
Modern enthusiasts say “abandon the Bible as Revelation” and “accept Das Kapital as Revelation”. But which is more mythic, “the Stories of Eve and Adam” or “the theory of surplus capital”? See Thomas Sowell’s book, Marxism, on that one.
