There is a very good article on St. Anselm’s view of the atonement at the “Christ In All of Scripture/Theology of G.C. Berkouwer” blog. He evaluates the so-called “satisfaction theory” of the atonement of Anselm and offers some insightful criticisms. Although Anselm wrote in “commercial language” about the atonement, he has a personal view of God that seems to indicate that Anselm went further than merely a commercial atonement. The author (thus far, he seems anonymous) points to a disconnect in Anselm’s understanding in the person of Christ. He insisted that Christ was a man in life, but suffered as the God-man in death. Putting it this way, says the author, indicated a failure to exposit the unity of Christ’s person.
