At Smalcald the first duty imposed upon the scholars and theologians was once more to discuss the Augustana and the Apology carefully, and to acknowledge both as their own confessions by their signatures. Thereupon they were, in a special treatise, to enlarge on the Papacy. The Strassburg delegates report: "It has also come to pass that the scholars received orders once more to read the articles of the Confession and to enlarge somewhat on the Papacy, which they did." (Kolde, _Analecta,_ 298.) However, since neither the Augustana nor its Apology contained an article against the Papacy, the demand of the princes could only be satisfied by a special treatise, the "Tractatus de Potestate et Primatu Papae," which Melanchthon wrote and completed by February 17, whereupon it was immediately delivered to the princes. The princes had furthermore ordered the theologians, while reviewing and discussing the Augustana (and its Apology), to reenforce its doctrine with additional proofs. Owing to lack of time and books, this was not carried out. February 17 Osiander reports to the Nuernberg preachers: "We are enjoying good health here, although we traveled in stormy weather and over roads that offered many difficulties, and are living under a constantly beclouded sky, which unpleasantries are increased by troublesome and difficult questions in complicated matters.... The first business imposed on us by the princes embraces two things: first, to fortify the Confession and the Apology with every kind of argument from the Holy Scriptures, the fathers, councils, and the decrees of the Popes; thereupon, diligently to discuss in detail everything concerning the Primacy, which was omitted in the Confession because it was odious. The latter we completed so far to-day that we shall immediately deliver a copy to the princes. The former, however will be postponed to another time and place, since it requires a longer time, as well as libraries, which are lacking here." (_C. R._ 3, 267.)
