The Five Solas: God's Perpetual War Against Rome

In the Reformation, the Reformers developed a systematic formulation that delineated the distinction of the biblical Christian faith from the corrupted version held by Rome. These doctrines have come to be known as the Five Solas, from their Latin forms.

Sola gratia, by grace alone. The Bible says that justification is by the condescending mercy of God. It cannot be due to any will or worthiness in the sinner because there is none. 

Sola fide, by faith alone. For those whom God has mercifully chosen to save, that justification is applied to them by means of faith. That is, faith is not meritorious, but is rather an instrument for applying justification. 

Solus Christus, on the basis of Christ alone. Everything necessary to justify God's people was achieved by the atoning work of Jesus, i. e., His perfect life, atoning death, and victorious resurrection. No additional intent, ritual, or action of men is necessary or possible, because Jesus did all that was necessary. 

Soli deo gloria, for the glory of God alone. God's purpose in justifying His people was not for our sakes, though we are certainly the beneficiaries. He did it to display the glories of His mercy and to glorify His Son with a church. 

Sola scriptura, in Scripture alone. Everything necessary to know about our sin, God's judgment, the redemption purchased by Christ, and the life of sanctification is and can be found in the Bible alone, using the ordinary means of reason, illuminated by the Holy Spirit. No human tradition added to Scripture or in its place can ever bind the conscience of the man of God. 

Even after the five centuries which have passed since the start of the Reformation, these truths have not changed. Nor has Rome ever repented of her errors here opposed. When professed Protestants practice fellowship and cooperation with the Catholic Church, it is not because she has given up her errors, but because the Protestants have accepted them.
