We have just become acquainted with the life and thought of the Puritan John Owen. We saw that he providentially arose from his anti-Puritan Laudian context at Oxford to become a Reformed theologian of the highest caliber and a prominent individual during the time of the Commonwealth and Protectorate. We now take a more in-depth look at his theology, which demonstrated a broad intellect. Owen pursued grand projects, meshing together varied disciplines such as linguistics, biblical exegesis, historical theology, and doctrine. Specifically, his unique emphasis on the Trinity profoundly shaped his theology.
