 Published under the pseudonym Ambrosius Sehmann von Caminiez (an anagram of his real name), his "Muthmassliche Zeit-Bestimmung" set out Zimmermann's belief that the dramatic upheavals ushering in Christ's kingdom on earth would occur in or around 1693.As his superiors in the Lutheran church viewed millenarianism as a dangerous heresy, Zimmermann was removed from his ministry in 1685.Another charge raised against him was that he adhered to the theosopher Jakob Böhme, whose complete works had been published in 1682.
