As a united Protestant church, it combined both Lutheran and Reformed traditions (Prussian Union).
Following the second constitution of the German Democratic Republic (GDR), enacted on 9 April 1968 and accounting for its de facto transformation into a communist dictatorship, the church bodies were deprived their status as statutory bodies (German: Körperschaft des öffentlichen Rechts) and the church tax, automatically collecting parishioners' contributions as a surcharge on the income tax, was abolished.
The area covered by the Evangelical Church of the Church Province of Saxony was equivalent to the old Prussian Saxony province, similar to the East German state of Saxony-Anhalt (1946–1952; except of former Anhalt) and small parts of the states of Brandenburg and Thuringia.
Some holders of the general superintendency were royally styled as bishop, then still considered a rather non-Protestant title.
In 1933 Nazi-submissive German Christians, then dominating the legislative general and provincial synods, introduced the title bishop for the spiritual leaders, including their hierarchical supremacy over other church collaborators.
