Aleinu, which concludes each of the three daily prayers in Judaism, describes the aspiration of all of humanity acknowledging God and calling in His name, fulfilling the verse, “God shall be One and his Name One” (Zechariah 14:9).

The theology behind this prophetic vision is the subject of this book. God Shall Be One weaves together the words of Israel’s prophets and sages throughout the ages to tell the story of a largely overlooked conception of the relationship between Judaism and other religions – offering a healing approach.

Especially now, in a globalized society that has seen increased violence in the name of religion, there is an urgent need for a cogent argument for mutual respect and cooperation.
