Some today have posited that the Lutheran view of the law only has the first two uses (to restrain evil, and to act as a pedagogue to point us to Christ). However, it is clear that not all Lutherans rejected the third use of the law. In fact, the evidence rather points to the opposite conclusion. Take this section from the Form of Concord (Schaff, Creeds of Christendom, III, pp. 130-131):
Article 6. Of the third use of the law. Statement of the Controversy. Since it is established that the Law of God was given to men for three causes: first, that a certain external discipline might be preserved, and wild and intractable men might be restrained, as it were, by certain barriers; secondly, that by the Law men might be brought to an acknowledgment of their sins; thirdly, that regenerate men, to all of whom, nevertheless, much of the flesh still cleaves, for that very reason may have some certain rule after which they may and ought to shape their life, etc., a controversy has arisen among some few theologians concerning the third use of the Law, to wit: whether the Law is to be inculcated upon the regenerate also, and its observation urged upon them or not? Some have judged that the Law should be urged, others have denied it.
The rest of the article clearly and explicitly affirms the third use of the law. The last sentence quoted here, however, might be a reasonable explanation as to why this misperception of Lutheranism has arisen: some Lutherans may have denied the third use of the law.
