Martin Luther, Freedom of a Christian (1520)

German monk Martin Luther’s attempt to reform the Catholic church from within developed into a new branch of Christianity known as Protestantism. After his excommunication by Pope Leo X in 1520, Luther published several treatises that attacked church authority, clerical celibacy, and the sacraments while elucidating his evangelical theology. He set forth the guiding principles of his beliefs with particular clarity in Freedom of a Christian. Although originally written in Latin and addressed to the pope, the tract was soon translated into German and widely circulated among Luther’s ever-growing number of followers. In the excerpt that follows, Luther defined what became a central tenet of the reform movement: faith in Christ and his promise of salvation is all that a Christian needs to be saved from sin.

Many people have considered Christian faith an easy thing, and not a few have given it a place among the virtues. They do this because they have not experienced it and have never tasted the great strength there is in faith. It is impossible to write well about it or to understand what has been written about it unless one has at one time or another experienced the courage which faith gives a man when trials oppress him. But he who has had even a faint taste of it can never write, speak, meditate, or hear enough concerning it. It is a living “spring of water welling up to eternal life,” as Christ calls it in John 4 [:14].

As for me, although I have no wealth of faith to boast of and know how scant my supply is, I nevertheless hope that I have attained to a little faith, even though I have been assailed by great and various temptations; and I hope that I can discuss it, if not more elegantly, certainly more to the point, than those literalists and subtile disputants have previously done, who have not even understood what they have written. . . .

First, let us consider the inner man to see how a righteous, free, and pious Christian, that is, a spiritual, new, and inner man, becomes what he is. It is evident that no external thing has any influence in producing Christian righteousness or freedom. . . . It does not help the soul if the body is adorned with the sacred robes of priests or dwells in sacred places or is occupied with sacred duties or prays, fasts, abstains from certain kinds of food, or does any work that can be done by the body and in the body. . . .

One thing, and only one thing, is necessary for Christian life, righteousness, and freedom. That one thing is the most holy Word of God, the gospel of Christ, as Christ says, John 11 [:25], “I am the resurrection and the life; he who believes in me, though he die, yet shall he live”; and John 8 [:36], “So if the Son makes you free, you will be free indeed”; and Matt. 4 [:4], “Man shall not live by bread alone, but by every word that proceeds from the mouth of God.” Let us then consider it certain and firmly established that the soul can do without anything except the Word of God and that where the Word of God is missing there is no help at all for the soul. If it has the Word of God it is rich and lacks nothing since it is the Word of life, truth, light, peace, righteousness, salvation, joy, liberty, wisdom, power, grace, glory, and of every incalculable blessing. . . .

You may ask, “What then is the Word of God, and how shall it be used, since there are so many words of God?” I answer: The Apostle explains this in Romans 1. The Word is the gospel of God concerning his Son, who was made flesh, suffered, rose from the dead, and was glorified through the Spirit who sanctifies. To preach Christ means to feed the soul, make it righteous, set it free, and save it, provided it believes the preaching. Faith alone is the saving and efficacious use of the Word of God. . . . Therefore it is clear that, as the soul needs only the Word of God for its life and righteousness, so it is justified by faith alone and not any works. . . .

When you have learned this you will know that you need Christ, who suffered and rose again for you so that, if you believe in him, you may through this faith become a new man in so far as your sins are forgiven and you are justified by the merits of another, namely, of Christ alone. . . .
