Four of our articles this month were written by four of the greatest Christian giants of the Twentieth Century. Benjamin Warfield was Professor of Theology at Princeton Seminary, (1887-1921). John Murray was Professor of Theology at Westminster Seminary, (1937-1966). Jay Adams is Director of Advanced Studies at Westminster Seminary in California. And R.J. Rushdoony is the president of Chalcedon, a Christian educational organization devoted to research, publishing and to cogent communication of a distinctly Christian scholarship to the world. All four of them were/are prolific writers. I own thirteen of Warfield's books, twelve of Murray's books, twenty or so of Adams' books, and over twenty-five of Rushdoony's books.
