This course is a study of the Christian doctrine of the Holy Spirit with an emphasis on Seventh-day Adventist history and theology. We will first endeavor to trace the development of the doctrine of the Trinity, discuss some of the issues and problems associated with a Trinitarian understanding of God and review the biblical foundation for this doctrine. The course will then focus on the biblical doctrine of the Holy Spirit, His person and His role and work in the plan of salvation and in the Church. We will also discuss many interrelated theological concepts to gain a good understanding of the person, role and work of the Holy Spirit. This course will attempt to help students think in theological terms and articulate their thoughts on various theological themes related to the Christian doctrine of the Holy Spirit.
