The Tetrapolitan Confession, also called the Strassburg and the Swabian Confession, is the oldest confession of the Reformed Church in Germany, and represented the faith of four imperial cities, Strassburg, Constance, Memmingen, and Lindau, which at that time sympathized with Zwingli and the Swiss, rather than Luther, on the doctrine of the sacraments.
It was prepared in great haste, during the sessions of the Diet of Augsburg, by Bucer, with the aid of Capito and Hedio, in the name of those four cities (hence the name) which were excluded by the Lutherans from their political and theological conferences, and from the Protestant League. They would greatly have preferred to unite with them, and to sign the Augsburg Confession, with the exception of the tenth article on the eucharist, but were forbidden. The Landgrave Philip of Hesse was the only one who, from a broad, statesmanlike view of the critical situation, favored a solid union of the Protestants against the common foe, but in vain.
Hence, after the Lutherans had presented their Confession June 25, and Zwingli his own July 8, the four cities handed theirs, July 11, to the Emperor in German and Latin. It was received very ungraciously, and not allowed to be read before the Diet; but a confutation full of misrepresentations was prepared by Faber, Eck, and Cochlaeus, and read Oct. 24 (or 17). The Strassburg divines were not even favored with a copy of this confutation, but procured one secretly, and answered it by a “Vindication and Defense” in the autumn of 1531.*
