Heermann received theological training as a result of a vow his mother made when he was very ill as a child. After ordination, he taught at the university, but had to stop in 1607 after contracting an eye infection.
Four years later, he became a deacon, then the Lutheran pastor, in Koeben. His ministry was interrupted several times by the Thirty Years’ War, but the faithful minister resumed whenever the fighting died down.
In 1634, medical problems forced him to stop preaching, and he finally retired in 1638.
