This series by Michael Horton first appeared in the March/April 2010 issue of Modern Reformation. Horton begins by pointing out that the concept of inerrancy goes back to the ancient Church, but was most clearly developed by Princeton theologians A.A. Hodge and B.B. Warfield in their 1881 book, Inspiration. These men emphasized that the Holy Spirit worked through limited human authors in a centuries-long process to produce the Bible. Hodge and Warfield defined inerrancy not as the absence of technical errors but as the truthfulness in what the biblical writers were affirming.
