Luther's doctrine of 'justification by faith,' According to Encyclopedia Britannica, Luther himself said that what set him apart from the other reformers is that he went to the theological root of the church’s corruption, the perversion of the doctrine of redemption and grace. The key foundations of Luther’s reform for the church were: scripture alone and justification by faith alone. For the Protestant, or actually, Lutheran, Reformation in Germany and Switzerland, Luther’s idea of justification by faith alone was the origin.
