Solus Christus (Latin for “Christ alone”) is one of the five core solas (Latin for “alone”) that emerged as foundational principles during the Protestant Reformation in the 16th century. These solas—Sola Scriptura (Scripture alone), Sola Fide (faith alone), Sola Gratia (grace alone), Solus Christus (Christ alone), and Soli Deo Gloria (glory to God alone)—served as rallying cries for reformers like Martin Luther, John Calvin, and Ulrich Zwingli to reclaim biblical Christianity from what they saw as medieval Catholic distortions.
