Do you have any basis for this other than “I think”?
For most of the history of Christianity, the laity (and even most ordinary clergy) had no access to The Bible - actual texts were rare, and access was restricted - and for much of that time, they would not have been able to read it even if they had (and even if they had been literate), because it was not written in or translated into vernacular languages. Only Church trained, Church approved scholars would have had access, and their interpretations were strongly guided by the views of the ancient Church Fathers, the greatest of whom, St Augustine, had taught that when a Biblical passage was in superficial conflict with reason and (what then passed for) established science, it was the literal interpretation of the Biblical passage that should give way. (Otherwise, he argued, Christianity would be made to look foolish, and old lose adherents as a result.) The religious doctrines that most people were taught (in sermons, and so forth) was not based directly upon the Bible, but on tradition, and on Bible passages as they had been interpreted (and then taught to the ordinary priesthood) by Church-approved, highly educated experts, whose interpretations were often very far from literal.
Bibles in general, and Bibles translated into the vernacular, in particular, began to become widely available to laity and lower clergy alike only after the invention of printing and the Protestant Reformation, but it is well documented, as the OP and other posters in this thread have noted, that Fundamentalism and Biblical Literalism, an insistence that the Bible is the major source of Christian truth, and must be interpreted as literal truth, is a viewpoint that does not take hold until the late 19th or early 20th century, specifically in America, and as a reaction to the liberal, science-friendly Christianity that then prevailed (and that had, by then, embraced Darwinian evolutionary theory as a scientific justification for social change). Fundamentalist Christianity is a movement of reaction against the rapid social change of modern times, that is often associated with the rise of science (hence fundamentalist hostility to science in general, and evolutionary theory in particular). Biblical literalism, rather than being the basic motivation behind the movement, is a tool it uses in its resistance to scientific modernity, and to justify its social conservatism. The movement’s roots in Christian tradition are extremely shallow.
