Due to his birth to a non-Jewish mother, Cardozo was technically not halakhically Jewish (natural-born Jewish status is conferred through one’s mother), but at age sixteen he formally converted to Judaism through the Amsterdam Rabbinate, formed by Hacham Salomon Rodrigues Pereira, Chief Rabbi Aron Schuster and Rabbi Benjamin Pels.
[7] He heads a Think Tank focused on finding new Halachic and philosophical approaches to dealing with the crisis of religion and identity amongst Jews and the Jewish State of Israel.
Rabbi Avrohom Gordimer, a rabbinic coordinator for the Orthodox Union, said that Cardozo has "accepted the approach of the Conservative movement, which postulates that Halacha is not objective divine truth, is not fixed, and that it must change in accordance with the values of the times and with various needs.

[10] Cardozo maintains that his views remain within the acceptable realm of Orthodoxy and on numerous occasions distanced them from the Reform & Conservative movements.
