After the war the congregation could develop again and ministered – among others – a large British-born artisan population as well as American, German, Indian, Chinese, Finnish and Russian Christians. In 1921 Charles Andrew Schönberger came to Germany and opened a branch of the Anglican Hebrew Christian Testimony to Israel in Berlin, right opposite to St. George's on Oranienburger Straße 20/21. They won a number of proselytes among the Jews of Berlin for the Anglican congregation. When the Nazi persecution of Jews and Jewish-born Christians, likewise discriminated (see The forsaken children of the Church – Protestants of Jewish descent), turned the more and more unbearable, the Hebrew Christian Testimony to Israel relinquished its premises on Oranienburger Straße 20/21 to Heinrich Grüber's help organisation, the Bureau Grüber (), on 7 December 1938. The Bureau Grüber cooperated in its efforts with Bishop George Bell, who had gained his sister-in-law Laura Livingstone to run the Berlin office of the "International Church Relief Commission for German Refugees". A plaque at the new building on Oranienburger Straße 20/21 commemorates these joint Anglican and Confessing Church efforts.
