Reformed or Presbyterian theology is often referred to simply as "covenant theology." That's because there's nothing more central to Reformed thinking than the fact that God has sovereignly and graciously established a covenant relationship with sinful men through his only begotten Son, Jesus Christ, the mediator of the covenant. Covenant theology is involved in every doctrine the church holds, either explicitly or implicitly. In this work, Dr. Walker traces the development of the doctrine of the covenant in Scripture, considering also the historical opinions of some of the church's great theologians. His goal is to make covenant theology accessible to every man.
