Pre-exilic Judaism was polytheistic (or henotheistic). Some have claimed the Shema as a strict monotheistic statement, but later in the same book that declares the Shema there are statements that imply to polytheism. Post-exilic books describe the strictest form of monotheism comparable to Haugs interpretation of Gathic Zoroastrianism. The Jews today don't practice original Judaism. They've either reinterpreted the nature of their god according to the interpretation of god in the intertestimenal books which they threw out, or by Christianity's interpretation of Judaism. Christians, Muslims, and Zoroastrians all venerate angels and saints, in addition to God, but they are all as monotheistic as each other, unless one considers Haugs argument for strict monotheism in the Gatahs: the Devil essentially being an abstract concept representing the negation of good. There are two arguments that can be made in regard to Christianity Islam and Zoroastrianism. That they describe a cosmic dualism and therefore not monotheism or God is really omnipotent, will defeat the Devil at the end of time, and therefore these are monotheistic religions.
