In 1900, he graduated from Calvin Theological seminary and took up the pastorate of First Christian Reformed Church in Allendale, Michigan. Two years later, he went to Princeton Theological Seminary, and within two years had earned his BD degree. Then he returned to West Michigan to pastor Oakdale Park Church located in Grand Rapids. Berkohf was an outstanding teacher, and the prolific author, his magnum opus, Systematic Theology, first published in 1934, has long been the standard textbook.
