What is Christian doctrine? What is systematic theology? Why should Christians study it? How should we study it? There is a huge difference too between the study of religion and the study of theology. The study of religion has to do with the worship practices of humans in relation to their deity. Theology, by contrast, is the study of the nature and character of God. R.C. Sproul tell us, “Everything we learn —economics, philosophy, biology, mathematics—has to be understood in light of the overarching reality of the character of God.” That is why theology was called “the queen of the sciences” and philosophy “her handmaiden.” This eleven-volume of work aims to reinstate the Queen into her rightful place on the throne.
