Being instructed from the prophetic and apostolic Scriptures, we are sure about our doctrine and Confession. By the grace of the Holy Spirit, our minds have been confirmed. Therefore, this Book of Concord should be published. It is necessary that, amid so many errors in our times, as well as causes of offense, there should exist a godly explanation about all these controversies. It should be derived from God's Word by which pure doctrine might be distinguished from the false. This matter is important. There are contentious people not bound to any formula of the pure doctrine. They stir up controversies, according to their good pleasure. The result is that the pure doctrine is hidden and lost. Then nothing is passed on to future generations except academic opinions. We owe our subjects this service: we should diligently care for the things that apply to this life and the life to come. We should take pains, with our utmost ability, to attend to those matters that promote (a) the extension of God's name and glory; (b) the spread of His Word (from which alone we hope for salvation); (c) the peace and tranquility of churches and schools; and (d) the instruction and consolation of disturbed consciences. We must do this. For it is a fact that this work of Christian concord has already been longed for and expected with anxious prayers and the greatest desire by many good and sincere people.
