Catholic Doctrines on the Jewish People after Vatican II establishes that the Catholic Church has a new teaching about the Jewish people: the covenant made with God is irrevocable. D'Costa faces head-on three important issues arising from the new teaching. First, previous Catholic teachings seem to claim Jewish rituals are invalid. He argues this is not the case. Earlier teachings allow us positive insights into the modern question. Second, a nuanced case for Catholic minimalist Zionism is advanced, without detriment to the Palestinian cause. This is in keeping with Catholic readings of scripture and the development of the Holy See's attitude to the State of Israel. Third, the painful question of mission is explored. D'Costa shows the new approach safeguards Jewish identity and allows for the possibility of successful witness by Hebrew Catholics who retain their Jewish identity and religious life.
