Johann(es) Fleck (Latinised: Flaccus, (1559 in Zwickau[1] – 30 July 1628 in Küstrin) was a German Lutheran pastor, superintendent and court and cathedral preacher.
"In 1597, Superintendent Johannes Fleck railed from the pulpit that in future the church should be kept closed because young and old adulterers held their secret conversations in it and full-blooded drunkards purified themselves in it"[2] When the Franciscan Monastery Prenzlau [de], which had been repaired for the Protestant church by order of the electoral captain Bernd von Arnim in 1597, was consecrated on 24 February 1598, Fleck preached the first Lutheran sermon.
[3] In 1601, Joachim Frederick, Elector of Brandenburg appointed him as court and cathedral preacher in Berlin.
In this capacity, he preached the inaugural sermon (which has survived in print) at the newly founded Joachimsthalsches Gymnasium in 1607.
Under John Sigismund, Elector of Brandenburg, Fleck was transferred to Küstrin as inspector (superintendent) in 1611.
