Nineteenth-century interpretation reflected traditional Protestant devotion to scripture and hermeneutical conventions from American experience, especially the democratic empowerment of ordinary people and a republican resentment of intellectual aristocracy. In the antebellum era, interpretations flowed from long-standing Protestant convictions adjusted to republican common sense. Contention over the Bible and slavery generated the sharpest differences. After false starts from Tom Paine in the 1790s and a few New Englanders in the 1840s, modern biblical criticism affected interpretations from the 1870s. In the postbellum era, some Protestants adopted a more liberal understanding of scripture because of the earlier standoffs over slavery. Groups previously marginalized (Catholics, Jews, skeptics, women, African Americans) also became more visible.
