Moscheles was still a practising Jew in Vienna in 1814–15. His wife noted that he was a member of the congregation in Vienna, and that he wrote for the Vienna Jewish community an oratorio celebrating the peace. Throughout his life, like many other musicians of Jewish origin, he remained close to other musicians of similar descent such as Felix Mendelssohn, Anton Rubinstein, Joseph Joachim and Ferdinand Hiller. He also remained in contact with patrons of Jewish origin such as the Eskeles family in Vienna, the Leo family in Paris, and the Rothschilds in England. He married Charlotte Emden, daughter of a Hamburg Jewish banker and a cousin of Heinrich Heine, in a Hamburg synagogue in 1825. Nonetheless, after he settled in England, Moscheles became a member of the Church of England.
