The Five Solas of the Reformation
Sola Scriptura (Scripture Alone) maintains that Scripture alone (consisting of the Old and New Testaments, inerrant in their original autographs) is the inspired, infallible and inerrant Word of God; that it is the only recorded revelation of God; that it is the only infallible rule for the catholic Church on all matters relating to the historic Christian faith and practice; and that it alone is binding on the conscience (2 Timothy 3:15-16).
Sola Fide (Faith Alone) maintains that the justification (salvation) of sinners before the Holy God is by faith alone (Romans 5:1; Ephesians 2:8-9). Upon casting himself at the mercy of God and committing himself to the Lord Jesus Christ by faith, the sinner is justified by the grace God through the Lord Jesus Christ. The righteousness of Jesus Christ, “the Lamb of God who came to take the sin of the world” (John 1:29), is then imputed to the believing sinner.
Sola Christus (Christ Alone) maintains that Christ alone is the Mediator between the Holy God and sinful man. Christ, the eternal Son of God, is the only Redeemer of God’s elect. Through Christ, God did what the Law could not do for sinful man. Christ gave Himself over to death on behalf sinners in order to reconcile God’s children to Himself through the Cross (Isaiah 53; John 1:29; John 3:16-17; Acts 4:12; 2 Cor. 5:21).
Sola Gratia (Grace Alone) maintains that the salvation (justification) of sinful man is solely an act of God’s free grace in which He declares forgiveness to the sinner and accepts him as righteous in His sight, only for the righteousness of the Lord Jesus Christ that He imputes to all who believe in Him. The sinner makes contributes nothing to his salvation. It is all of grace (Romans 6:23; Ephesians 1:6, 12, 14; 2:4-10; Titus 3:5-7).
Soli Deo Gloria
Soli Deo Gloria (To God Alone Be the Glory) maintains that it is absolutely necessary that man should submit to God in all things. The Lord God is Sovereign over the souls of men. He is the Giver of all good gifts and the Sustainer of all of His Creation, and as the merciful Saviour and Judge of all men, He deserves to be worshipped and glorified by all of His creatures in all things (1 Chronicles 16:23-34; Romans 11:33-36; 1 Corinthians 10:31).
