In 1870 under royal appointment returned to the parish of St. Hedwig in Berlin, as episcopal delegate for Brandenburg and Pomerania and next made Honorary Canon in Wrocław.

As bishop, Herzog removed the pastors with dubious appointments and opposed the teaching of religion in the people's native language.
