Milne argues from primary Reformation and post-Reformation sources that Westminster Confession 1.8 teaches providential preservation of the complete wording of Scripture in accessible Hebrew and Greek copies, not merely preservation of doctrine or a recoverable text hidden across the manuscript tradition. Extended chapters examine Calvin, Cartwright, Whitaker, Jewel, the Westminster divines, John Goodwin, and James Ussher before contrasting their epistemology with Warfield and modern textual criticism.

The book's principal strength is its large archive of primary evidence, much of it drawn from early printed sources and Latin works. Its thesis is argued coherently and transparently, though some historical actors are pressed toward a more uniform word-for-word position than their acknowledgment of unresolved variants always permits.
