Annotatio III §.II: From the Reformed side — Wittenberg Formula never revoked, only declared; Helvetian approval; Zurich reply dated 4 May 1538 (not 1539 typo in Werenfels)
From the Reformed side: the Wittenberg Formula of Concord was never revoked — only declared (Crocius on the Augsburg Confession, p. 162).
The Swiss approved it point by point (Crocius, pp. 100 and 107).
Because some have doubted that approval, we must call the Helvetians’ own reply letters from Zurich to Luther as witnesses — written a little later, yet not as late as 1539 (the year a Berlin printing of Werenfels’s sermon assigns them, perhaps by typographical error, in this very year of my writing).
They were drawn up on 4 May 1538 — about half a year after Luther’s letter reached them — as Selneccer, Kirchner, and Chemnitz, the three most celebrated Lutheran historians of the Augsburg Confession, recount when they cite the letters in these words:
