After the Nazis seized power in 1933, more attacks followed and Ehrenberg's moral and pedagogical integrity were put in question.

Ehrenberg became one of the founders of the Confessing Church.
 He and four other Westphalian ministers had already formulated the "Bochum Confession" in May 1933.
The first of its kind, it contained a denial of Nazi ideology and a confession of Christianity's Jewish origins.
 In July 1933, he published 72 Leitsätze zur judenchristlichen Frage (Seventy-Two Theses to the Jewish-Christian Question), clearly stating his own opposition to anti-semitism and calling on the Protestant church to do the same.
After he was the target of attacks in Der Stürmer, and facing pressure from the German Christian church authorities, Ehrenberg asked for early retirement in 1937.
He continued, however, to work for the Confessing Church, whose ministers in Bochum openly showed solidarity with him.

In September 1938, he was barred from delivering any speech or sermon.
His home was destroyed in the pogroms of Kristallnacht and a few days later, he was taken to Sachsenhausen concentration camp.
In 1939, he was able to emigrate to England, thanks to the intervention and pledges of George Bell, Anglican bishop of Chichester.
He had had a correspondence with Bell and was perhaps more significant than Franz Hildebrandt or Bonhoeffer in convincing Bell of the growing crisis in German churches under the Nazi state.
His family joined him shortly afterward.
Ecumenism, religious unity, became increasingly important to him here.

Even though Ehrenberg was strictly anti-communist, his life was saved on several occasions by a communist trade union leader, in the Sachsenhausen concentration camp.

Ehrenberg spoke openly about the German confessional church in England in an effort to prevent the growing disaster in Germany.
George Bell also spoke out about Nazi interference in the church.
Ehrenberg and George Bell were of the same view that civilians and civilian infrastructure should not be affected by the ongoing war in central Europe.

His close friends included Pastor Dr. Werner Koch, a surviving member of the German resistance and the youngest brother of Hans Koch.
