The Westminster Confession

Christ the Only Mediator

Galatians 4:1-7

About this sermon

The sermon explores the theological doctrine of the Hypostatic Union, defining Christ as the eternal Mediator who is fully God and fully man in one person. It examines the six offices and roles of Christ, including prophet, priest, king, head of the church, heir of all things, and judge of the world, to demonstrate the completeness of His redemptive work. The teaching addresses historical heresies such as Arianism and Nestorianism to clarify the distinct yet inseparable natures of Christ, emphasizing that this understanding is rooted in Scripture and church history rather than modern invention. By distinguishing between ontological equality and economic roles within the Trinity, the sermon corrects misconceptions about the Son's subordination. The central message calls for a worship that is faithful to the biblical Christ, recognizing His sufficiency as the sole mediator between God and humanity.
