What is solus Christus?
Quick answer
"Solus Christus" — Christ alone — is the Reformation conviction that Jesus Christ is the only mediator between God and humanity. No priest, saint, sacrament, or work supplements his finished work.
"For there is one God, and there is one mediator between God and men, the man Christ Jesus" (1 Timothy 2:5).
Christ alone died for sin; Christ alone presents us to the Father; Christ alone is the way (John 14:6). To add to him is to subtract from him.
It is the foundation under all the other solas. Scripture alone tells us about him; faith alone unites us to him; grace alone gives him to us — and to God alone be the glory.
