Direct Answer Bercot says the stake is whether Scripture is treated as sufficient: making a non-biblical word the test of orthodoxy implies “essential truths” aren’t stated clearly enough in Scripture and invites later human authorities to claim Scripture-level status. The transcript critiques Rome and Orthodoxy explicitly; it does not directly apply the point to Protestants, though a reasonable inference is that any group can functionally elevate extra-biblical formulas above Scripture.
