§.XII strict close: Proof — Frederick Palatine Naumburg 1561 / Augsburg 1566; Philip of Hesse favoring Reformed
That the Reformed no less than the Lutherans have always been held Augsburg Confession associates appears (1) from Frederick the Palatine at Naumburg in 1561 and at the Augsburg Diet in 1566.
See more fully the Author of the ausführlichen Behauptung, Appendix pp. 36–43; Pareus, Irenicum, pp. 292 and 297; Crocius's German Summarische Nachricht… (nos. 123–130; pp. 54–58), and his Comment on Augsburg Confession Society, Q.2, caps. XVIII and XXI; also our Becmann, loc. cit., p. 99ff.
(2) From Philip, Landgrave of Hesse, who steadily favored the Reformed side and with great zeal pressed the more rigid into it by speech and many letters — in Chytraeus's Acts with the Zwinglians from p. 633ff.; Calixtus, On Tolerance of the Reformed, n. 62 (Batavian) and n. 65 (newest Helmstedt); and the History of the A.C. By three theologians, written in German and Latinized by Chemnitz's son-in-law.
