Solus Christus or In Christo solo, are both Latin terms that mean “in Christ alone.” The belief that Jesus Christ is the only mediator between God and humanity, and that salvation comes through Him and Him alone. Paul writes; “For there is one God and one Mediator between God and men, the Man Christ Jesus, who gave Himself a ransom for all, to be testified in due time.” (1 Timothy 2:5-6)

Peter boldly preached; “Nor is there salvation in any other, for there is no other name [Jesus] under heaven given among men by which we must be saved.” (Acts 4:12) This clearly emphasizes that salvation comes through Christ alone. Jesus declares, in John 14:6; “I am the way and the truth and the life. No one comes to the Father except through me.”  This is a clear and definitive statement that access to God the Father is only through Christ. This is the only way of salvation, and it is only found in Jesus Christ. Take a moment to read Colossians 1:15-20 which speaks to the supremacy of Christ. Stating that He is the image of the invisible God, the firstborn over all creation, the head of the Church and that He is the creator and reconciler of all things to Himself alone.

During the Protestant Reformation (1517-1750), the concept of Solus Christus was a response to the Catholic Church’s emphasis on the role of the saints and religious leaders as mediators between God and humanity. The reformers believed sincerely that the Bible teaches salvation for us is received through Jesus Christ alone. The Lord Jesus is the only mediator between God and humanity; all others are to be considered frauds.

It is not to neglect the undeniable fact that Solus Christus (in Christ alone) emphasizes the importance of atonement. The belief is that Jesus Christ’s death on the cross is how salvation is made available to humanity. The view is that salvation is received by grace alone, through faith alone, in the atoning work of Jesus Christ on the cross for us alone. Praise God for His great love for us all!
