Solus Christus
Christ is the unique and sufficient mediator of salvation.
What it is: The principle of solus Christus emphasizes that Jesus Christ is the unique and sufficient mediator between God and humanity.
How the religion understands it: This emphasis reinforces the centrality of Christ's person and work in salvation and tends to relativize mediations considered excessive or unnecessary. The focus falls on the cross, the resurrection, Christ's intercession, and exclusive trust in him.
Context: It is a formulation especially important in the controversies of the Reformation and continues to shape Protestant identity.
