Input: Question: What religious denomination was the church that Froehlich worked in in 1921? Passage:August Froehlich was born in 1891 in a well-to-do business family in Königshütte (now Chorzów) in Prussian Silesia. In 1912 young Froehlich started theological studies in Breslau to become a priest, but before completing it, at the break of the First World War, he was mobilized. He served in the elite 1st (Emperor Alexander) Guards Grenadiers. Soon, while on the Russian front, on 3 July 1915, in one of the first battles, he was seriously injured. Mistakenly taken for dead, he was left on the battlefield, found alive only the following day by German military medics. After his recovery, he resumed his military service, this time in France. Among other medals he received the Iron Cross - first and second class. He was wounded again and became a POW. He returned home to Breslau from British imprisonment in the autumn 1920, two years after the end of the war. He continued his theological studies in the theology faculty at the Breslau University. On 19 June 1921 August Froehlich was ordained a priest by Cardinal Adolf Bertram in the cathedral of Breslau Diocese. After his first mass in his home parish Saint Barbara in Königshütte, he was appointed by the Bishop of Breslau to the autonomous Berlin ecclesiastic province. He worked in Berlin and Pomerania.
