Introduction to Systematic Theology: Cologne Cadre Series by Louis Berkhof

The book discusses the major areas of Christian belief from a classic Reformed perspective. He covers areas like Theology proper, Anthropology, Christology, Soteriology, Ecclesiology, and Eschatology (such strange but essential terms!) And for each topic discussed, there is a historical overview. Thus, one gets a good dose of historical theology along with systematic theology. I found his definitions quite helpful in crystallizing a doctrine and making it sink in. Consider, for instance, his definition of God’s holiness: “That perfection of God, in virtue of which He eternally wills and maintains His own moral excellence, abhors sin, and demands purity in his moral creatures.” Concise. Clear. Powerful. This is an absolute essential work for any serious student of the Scriptures and as a service guide to their Christian Faith.
