Morton Smith, recently deceased, was professor of systematic theology at Greenville Presbyterian Theological Seminary and, before that, Reformed Theological Seminary in Jackson, MS. He was a giant theologian in the American Presbyterian tradition. He was the first stated clerk of the Presbyterian Church in America, and studied under John Murray, Cornelius Van Til, and G. C. Berkouwer. He wrote his Systematic Theology (2 vols.) based on his decades of lectures in the seminary classroom. It is not widely read, but it is fantastic, and I think it should have a place in the Logos library. I, for one, will buy it immediately if it is produced.
Logos should contact the librarian at GPTS if they are interested.
