The five solas of the Reformation, which distinguished the Reformers from the teachings of Rome, include sola scriptura (Scripture alone), solus Christus (Christ alone), sola fide (faith alone), sola gratia (grace alone), and soli Deo gloria (glory to God alone).
These five statements of the evangelical faith lay at the center of what distinguished the theology of the Reformation from the theology of the Roman Catholic church in the 16th century. Sola scriptura is the belief that because Scripture is God’s inspired Word, it is the only inerrant, sufficient, and final authority for the church. Solus Christus is the assertion that Christ alone is the basis on which the ungodly are justified in God’s sight. Sola fide maintains that the believer receives the redemption Christ has accomplished only through faith. Sola gratia proclaims that all of our salvation, from beginning to end, is by grace and grace alone. Because of these things, the Reformers held fast to the phrase soli Deo gloria, that only God receives glory for our salvation.
The five solas form the nucleus of the evangelical faith. They not only capture the gospel of Jesus Christ and explain how that gospel takes root in the sinner, but they also define where the authority of that gospel resides and to what end that gospel is preached and proclaimed. Although the phrase “five solas” may be more recent in its usage, the concepts are rooted in the 16th century Reformation. These five solas distinguished Reformers like Martin Luther, Philip Melanchthon, John Calvin, and so many others from the teachings of Rome. But at the heart of this divide was not merely a theological dispute, but a celebration of the gospel itself. The reformers were willing to lay their lives down for these solas first and foremost because they believed the gospel itself was at stake.
