Benjamin Breckinridge Warfield taught at Princeton Seminary for more than thirty years and was the last great representative of the Old Princeton theology before the seminary divided. He wrote across the whole field — the person of Christ, the work of the Spirit, perfectionism, the history of Reformed thought — but is best remembered for his account of the inspiration and authority of Scripture, which set the terms for a century of argument after him.
He was not the obscurantist his opponents supposed: he accepted much of the science of his day and wrote carefully about evolution. His wife was an invalid for most of their marriage, and he rarely left her for more than a couple of hours, which is part of why so much of his life took the form of writing.
