Gotthard Fritzsche went to Breslau after his gymnasium training, to receive his university training. There he studied under Johann Gottfried Scheibel. As was customary, after his university education, he served as a private tutor. At his first examination for entering the ministry, he declared himself to be against the Prussian Union, and was banned from ministry in the State church. He joined the underground Old Lutheran church as a "Flying Pastor", who travelled from place to place disguised as a travelling tradesman, performing secret worship services and rites to those opposed to the State church. After a time, he grew weary of the work, and he travelled to Hamburg.
