Solus Christus: Christ Alone
Last updated: 2026-04-10
Solus Christus means that Jesus Christ is the only mediator between God and humanity, and that his life, death, and resurrection are the exclusive and sufficient ground for our salvation. It denies the necessity of human merit, saints, or any other creature as a means of obtaining favor with God.
📖 The Exclusive Mediator
The principle of Solus Christus asserts that since the fall, humanity has no access to God apart from a mediator, and that Jesus Christ is the only one who can fill that role. As confessed in the 1689 LBCF Ch.22 §2, religious worship is to be given to God alone and must be offered through the mediation of Christ alone, excluding any other intercessors. This truth is anchored in the apostolic witness that there is one God and one mediator between God and man, the man Christ Jesus.

🛡️ A Sufficient Savior
To claim that anything is required for salvation beyond the work of Christ is to suggest that he is merely a 'half-Savior,' a notion the Belgic Confession Art. 22 rightfully rejects as blasphemy. Our justification is not earned through our own efforts, but is received by faith alone as an instrument to embrace the merits of Christ. The Heidelberg Catechism Q.67 confirms that the whole of our salvation depends entirely upon that one sacrifice of Christ on the cross. We are more flawed than we dared believe, yet because of Christ, we are more accepted than we dared hope.

The doctrine of Solus Christus is essential because human sin has created an infinite distance between us and a holy God, which only Christ—being both fully God and fully man—can bridge. Because he is the only mediator appointed by the Father, any attempt to seek access through other creatures is both unnecessary and a dishonor to his perfect work.
🚪 Access to the Father
Because of the radical depth of our depravity, we are by nature entirely barred from the presence of God. The 1689 LBCF Ch.8 §9 teaches that the office of mediator is proper to Christ alone and cannot be shared or transferred. This matters because if we attempt to find another advocate, we are essentially declaring that Christ's finished work is insufficient. As stated in the Belgic Confession Art.26, Christ himself loves us more than any creature possibly could, having laid down his life for us when we were his enemies. To look elsewhere is to misunderstand both our great need and the abundance of his grace.

⚖️ The Necessity of the God-Man
For a mediator to truly reconcile God and man, he must represent both parties effectively. The Westminster Larger Catechism Q.40 explains that it was requisite for the mediator to be both God and man so that the works of each nature could be accepted on our behalf. Christ is the only one who fits this description, as the Apostle Paul writes: "For there is one God, one mediator also between God and men, himself man, Christ Jesus" (1 Timothy 2:5). Because he is fully God, he has the authority and power to save; because he is fully man, he acts as our faithful representative who understands our infirmities and intercedes for us with sympathy.
