The idea of liberty or freedom has played a powerful role in the history of Western society and culture, but the meaning and understanding of liberty has undergone continual change and interpretation. In the Roman world, where slavery was a basic institution, liberty meant the condition of being a free man, independent of obligations to a master.
In the Middle Ages possessing liberty meant having special privileges or rights that other persons or institutions did not have.
The idea of liberty also has a religious dimension, and the reformer Martin Luther formulated a classic interpretation of liberty in his treatise On Christian Liberty (sometimes translated On the Freedom of a Christian). Luther writes that Christians were freed from sin and death through Christ, not through their own actions.
A Christian man is the most free lord of all, and subject to none; a Christian man is the most dutiful servant of all, and subject to everyone.
Although these statements appear contradictory, yet, when they are found to agree together, they will do excellently for my purpose. They are both the statements of Paul himself, who says, “Though I be free from all men, yet have I made myself a servant unto all” (I Cor. 9:19), and “Owe no man anything but to love one another” (Rom. 13:8). Now love is by its own nature dutiful and obedient to the beloved object. Thus even Christ, though Lord of all things, was yet made of a woman; made under the law; at once free and a servant; at once in the form of God and in the form of a servant.
Let us examine the subject on a deeper and less simple principle. Man is composed of a twofold nature, a spiritual and a bodily. As regards the spiritual nature, which they name the soul, he is called the spiritual, inward, new man; as regards the bodily nature, which they name the flesh, he is called the fleshly, outward, old man. The Apostle speaks of this: “Though our outward man perish, yet the inward man is renewed day by day” (II Cor. 4:16). The result of this diversity is that in the Scriptures
On effective preaching, especially to the uneducated, Luther urged the minister “to keep it simple for the simple." (Church
Of St. Marien, Wittenberg/The Bridgeman Art Library)
Opposing statements are made concerning the same man, the fact being that in the same man these two men are opposed to one another; the flesh lusting against the spirit, and the spirit against the flesh (Gal. 5:17).
We first approach the subject of the inward man, that we may see by what means a man becomes justified, free, and a true Christian; that is, a spiritual, new, and inward man. It is certain that absolutely none among outward things, under whatever name they may be reckoned, has any influence in producing Christ ian right eousness or liberty, nor, on the other hand, unrighteousness or slavery. This can be shown by an easy argument.
What can it profit to the soul that the body should be in good condition, free, and full of life, that it should eat, drink, and act according to its pleas ure, when even the most impious slaves of every kind of vice are prosperous in these matters? Again, what harm can ill health, bondage, hunger, thirst, or any other outward evil, do to the soul, when even the most pious of men, and the freest in the purity of their conscience, are harassed by these things? Neither of these states of things has to do with the liberty or the slavery of the soul.
. . . [A]nd since it [faith] alone justifies, it is evident that by no outward work or labour can the inward man be at all justified, made free, and saved; and that no works whatever have any relation to him. . . . Therefore the first care of every Christian ought to be to lay aside all reliance on works, and strengthen his faith alone more and more, and by it grow in knowledge, not of works, but of Christ Jesus, who has suffered and risen again for him, as Peter teaches (I Peter 5).
