Chapter 8 – Of Christ the Mediator

Chapter 8, Paragraph 1: Summary

This paragraph introduces Christ as the mediator of the covenant of grace. It teaches that God chose His Son, Jesus Christ, to fulfill this role from all eternity. Christ was appointed by God to reconcile sinners to Himself, making Him the only Savior and mediator between God and humanity. As mediator, Christ fulfills the offices of prophet, priest, and king, ensuring the salvation of His people.

The paragraph emphasizes that Christ was perfectly equipped for this role, being fully God and fully man. His divine nature ensured He could bear the infinite weight of God’s wrath, and His human nature ensured He could represent humanity. This union of natures made Him the perfect and sufficient mediator to redeem God’s elect.


Historical Context

This teaching reflects the Reformers’ emphasis on the sufficiency of Christ’s work for salvation, countering both the Roman Catholic view of multiple mediators (e.g., Mary and the saints) and heretical views that denied either Christ’s full deity or His full humanity. The Reformers highlighted the uniqueness of Christ as the only mediator appointed by God, essential for the salvation of sinners.

Chapter 8, Paragraph 2: Summary

This paragraph focuses on the person of Christ, teaching that He is both fully God and fully man in one person. As the eternal Son of God, He is of the same substance and equal with the Father. At the appointed time, He took on human nature, being conceived by the Holy Spirit and born of the Virgin Mary. In doing so, Christ became fully human, sharing all the attributes of humanity (body and soul) but without sin.

The union of Christ’s two natures—divine and human—occurred without blending or confusion. He remains fully God and fully man, each nature retaining its distinct properties, yet united in one person. This unique union qualifies Him to be the perfect mediator between God and humanity.


Historical Context

This teaching builds on the early church’s doctrinal battles over Christology, particularly the Council of Chalcedon (451 AD), which affirmed the two natures of Christ in one person. The Westminster Confession upholds this biblical and historical understanding, countering both ancient heresies (e.g., Arianism, which denied Christ’s deity, and Apollinarianism, which denied His full humanity) and any view that undermines the sufficiency of Christ’s mediation.
