This correspondence and the two articles from De Heraut marked a serious conflict between Kuyper and Gunning—a conflict that led to their parting of ways. The matter at issue was the authority of Scripture. The letters are dated A[msterdam], March 9, 1873 (pp. 906–913), January 20, 1879 (pp. 974–977), and Amst[erdam], January 26, 1881 (pp. 989–990). The two articles (pp. 924–932 and 933–935) are reprinted from De Heraut, no. 9, February 3, 1878 and no. 13, March 3, 1878. In his article of February 3, Kuyper publicly criticized Gunning’s view of Scripture, as set forth in the first installment of Het leven van Jezus (’s Gravenhage, 1878). At that point, however, Gunning had already withdrawn the installment. The second, shorter article discussed that fact as well as reactions to Kuyper’s first article. Only sections from the second article are reprinted in this volume.
