As an advocate of natural theology, J. A. Turretin had no interest in the decrees of God. He taught that the doctrine of predestination had only led to “wild excess” in Protestant circles. . . . For J. A. Turretin, the notion of sin and man’s unworthiness of salvation did not bear any implications for the divine decree.
