Joseph Herman Hertz put his theology into practice in his communal religious policy, which was mostly concerned with halakhah and its implementation. Hertz's commitment to the world outside the Jewish community is evident from his appointment as professor of philosophy at the University of the Transvaal, and his anti-Boer political activity, which led briefly to his expulsion from the country. If Jews were seen to be enjoying the rights of citizenship without fulfilling their responsibilities to the state, the general population would come to resent them. The Chief Rabbis saw it as part of their responsibility to exhort their co-religionists to work for the benefit of wider society, and show the non-Jewish community that Jews were making a valuable contribution, and Hertz fulfilled this function. Hertz's powers came not only from the United Synagogue but also from the Board of Deputies of British Jews.
