May 11 the Confession was so far completed that the Elector was able to submit it to Luther for the purpose of getting his opinion on it. According to Melanchthon's letter of the same date, the document contained "almost all articles of faith, _omnes fere articulos fedei._" (_C. R._ 2, 45.) This agrees with the account written by Melanchthon shortly before his death, in which he states that in the Augsburg Confession he had presented "the sum of our Church's doctrine," and that in so doing he had arrogated nothing to himself; for in the presence of the princes, etc., each individual sentence had been discussed. "Thereupon," says Melanchthon, "the entire Confession was sent also to Luther, who informed the princes that he had read it and approved it. The princes and other honest and learned men still living will remember that such was the case. _Missa est denique et Luthero tota forma Confessionis, qui Principibus scripsit, se hanc Confessionem et legisse et probare. Haec ita acta esse, Principes et alii honesti et docti viri adhuc superstites meminerint._" (9, 1052.) As early as May 15 Luther returned the Confession with the remark: "I have read Master Philip's Apology. I am well pleased with it, and know nothing to improve or to change in it; neither would this be proper, since I cannot step so gently and softly. Christ, our Lord, grant that it may produce much and great fruit which, indeed, we hope and pray for. Amen." (St. L. 16, 657.) Luther is said to have added these words to the Tenth Article: "And they condemn those who teach otherwise, _et improbant secus docentes._" (Enders, 7, 336.) Up to the time of its presentation the Augsburg Confession was diligently improved, polished, perfected, and partly recast. Additions were inserted and several articles added. Nor was this done secretly and without Luther's knowledge. May 22 Melanchthon wrote to Luther: "Daily we change much in the Apology. I have eliminated the article On Vows, since it was too brief, and substituted a fuller explanation. Now I am also treating of the Power of the Keys. I would like to have you read the articles of faith. If you find no shortcoming in them, we shall manage to treat the remainder. For one must always make some changes in them and adapt oneself to conditions. _Subinde enim mutandi sunt atque ad occasiones accommodandi._" (_C. R._ 2, 60; Luther, 16, 689.) Improvements suggested by Regius and Brenz were also adopted. (Zoeckler, _Die A. K._, 18.)
