The 20th Pomeranian provincial synod, 9–11 October 1946, had also decided to develop a new church order in order to reconstitute the Ecclesiastical Province of Pomerania as an independent regional Protestant church body. On 2 June 1950 the Pomeranian provincial synod adopted the prepared new church order and thus established the Pomeranian Evangelical Church, territorially comprising those parts of the former ecclesiastical province located in then East Germany (German Democratic Republic, GDR). By its new constitution its spiritual leader, titled bishop since late 1946, would continue to use that title. The Pomeranian Evangelical Church became a full member of the Evangelical Church in Germany and between 1950 and 2003 was a full member of the Evangelical Church of the old-Prussian Union, now a mere umbrella. Under communist pressure the Evangelical Church of the old-Prussian Union had to skip the term Prussian from its name and renamed as Evangelical Church of the Union (Evangelische Kirche der Union; EKU) on its general synod in December 1953. In 1956 the Pomeranian church counted 720,000 parishioners, about one third of them with refugee background.
