"Solus Christus" is a Latin phrase meaning "Christ alone." It emphasizes that Jesus Christ is the sole mediator between God and humanity, highlighting His unique role in salvation. This doctrine asserts that faith in Christ is the only means by which individuals can receive forgiveness and eternal life, rejecting any reliance on human efforts or other mediators. This principle is a key tenet of the Reformation, particularly in the teachings of Martin Luther and other reformers. It underscores the belief that salvation is a gift from God, accessible solely through the life, death, and resurrection of Jesus Christ.
