This useful and valuable monument of divine knowledge and experience therefore I dedicate to you, most Illustrious Prince, John Ernest; which, I doubt not, you will prize more than any monuments of marble or of brass. For I know it is your desire that this noble work of Martin Luther should be preserved for the Church's sake; and I am equally assured that you love and cherish it with a pious regard, and after the example of your father; and I am also persuaded that you love the author of it; which also you do after the example of your reverend father, that most upright prince, Elector John, Duke of Saxony, whose worth we thus deservedly record; who, although he was far inferior to our most eminent leaders, whom I have before mentioned, Abraham, Isaac, Jacob and Joseph; yet I may justly rank him with that Pharaoh, King of Egypt, whom Joseph instructed in the true knowledge of God; and who gave a quiet dwelling to the family of Jacob. For thus your father also learned the Gospel with a holy desire that he might worship God. And he cherished and adorned the churches, and devoted all his counsels with the greatest moderation, to the common peace and tranquility of Germany.
Receive therefore, Illustrious Prince, this great work, which is now dedicated to you; that by reading these wonderful histories of the government, the perils, and the defense of the Church of God, you may learn to govern and strengthen your own exalted mind.
The reason why this commentary did not appear all at once, but in separate volumes, was because the labor of collecting and committing it to paper was very great; and we have not much idle time at our disposal, from the duties of our calling, as many dream we have; nor as those have, who only vaunt and talk of their great and numerous good works. I hope however that this my candid confession will be accepted by the reader, if I shall put into his hands a part of our labors first; though it is not a small part; and I promise that the remainder shall be added to it in a short time. For as one of old says, "A godly mind surmounts the hardest toil."
We who are engaged in church work have not only the labor of commenting and teaching, but we have also to endure many other burdens; and that, too, with much courage and firm determination of mind.
Nor am I deterred from my purpose even by the opinions of those, who say that nothing which our adversaries advance, who reproach this kind of doctrine (which, through the goodness and mercy of God, sounds forth in our Church), ought to be published to the world. For God's will is that he should be proclaimed aloud, both by the living voice and by the writings of his Church. Hence it is said concerning the Church's living voice, "Out of the mouths of babes and sucklings hast thou perfected praise." And concerning her writings, "These things shall be written for the generation to come." God's will is, that the doctrine revealed by him should be delivered faithfully and purely to posterity. And his will also is that we should inculcate it by speaking, by discoursing, by commenting, and by writing; that it might become familiarly known to us. And this continual meditation and application of the pen are of essential service to the promotion of godliness.
In a word, on what subjects can we meditate and what things can we commit to paper more useful and important than these? I approve of the labors of all, who devote themselves to the useful arts. I praise those who describe the nature and properties of plants and adorn any of the arts given us from above. But it is not more the duty of men to philosophize upon plants or upon the anatomy of the human body, than to collect with a godly intent those things which were delivered to us of God, attended with sure and certain testimonies.
And as to our adversaries, who reproach the doctrine of our Church, all such are refuted in this very book of Genesis by those sure witnesses, Abraham, Isaac, Jacob and Joseph. Since, therefore, we have such eminent men as these, as witnesses on our side; nay, as our teachers, too; let us not be moved by the calumnies and reproaches of the wicked. Reader, farewell. To God I commend you.
Christmas, 1544.
