Louis Berkhof, a former president of Calvin Theological Seminary, published this overview of systematic theology in 1938. He wrote it for high school students.
It is actually a summary of a summary. His first set of books was Reformed Dogmatics which he later updated and published as his exhaustive Systematic Theology.
He then summarized that first work into A Manual of Reformed Theology (available as PDF). Some friends asked him if he would shrink that down for students, so he produced this little work. It’s one of the best summaries of Christian theology from a Reformed perspective.
