Biblical influences Charles Mopsik and
Moshe Idel suggested that mystical currents within Judaism find their source in writings attributed to the prophet
Elijah, "the oldest and most prominent figure" of biblical mysticism, the celestial messenger who initiates the reader into the secrets of the
Torah. The figure of Elijah holds a significant place in
apocalyptic literature that emerged in the 3rd century BCE in the
Jewish schools of the ancient East. This literature of resistance was formed by authors who critically observed the world they lived in while conveying a message of hope. It is associated with another biblical figure, the prophet
Ezekiel. His vision of the
Merkavah (the "Chariot of God") plays an important role in synagogal literature. Philo's influence on ancient Jewish Christianity is considerable, and his influence on synagogue Judaism is no less significant. The figures of the
zodiac and the god
Helios systematically appear in ancient synagogues. the righteous become light in the afterlife, taking on the form of an angel or a star. This conception, specific to synagogal mysticism, is not widely appreciated by the rabbis. The rabbis, at that time, were wary of messianic conceptions. They often involved processes of divine emanation that they disapproved of. The tendency of the rabbis, until the beginning of the 6th century, was "deeply anti-messianic," as noted by Philip Alexander.
Binitarianism Daniel Boyarin introduces the concept of
binitarianism, which refers to a dual identity of God, with a transcendent, absent, and unrepresentable aspect, as well as an immanent, present, and representable aspect, within both synagogal Judaism and Christianity.
Justin Martyr, one of the early
Church Fathers, considered this understanding of the divine as one of the foundations of Christian thought, while the rabbis regarded it as heresy, notes Boyarin. The necessity to integrate, at least partially, the elements of synagogal mysticism into
rabbinic literature to satisfy a society for whom the synagogue remained an essential place, imposed on the rabbis to break away from
heresiology. According to Boyarin, this was a significant change. Rabbinic Judaism no longer conceived of heretics among the Jews. It abandoned its initial project to embrace a plurality of beliefs, sometimes contradictory, focusing on practices rather than faith. "This directive becomes almost omnipresent and foundational for later forms of Rabbinic Judaism. There is now practically no possibility for a Jew to cease being Jewish because the very notion of heresy has been ultimately rejected, and Judaism (even if the term is anachronistic) refused to be, ultimately, a religion", concludes Boyarin. The nature of the opposition between ancient Christianity and Rabbinic Judaism lies in the fact that "they belong to completely different categories," notes Mimouni, who further explains, "From the Christian perspective, Rabbinic Judaism and Christianity fall into the category of religions [...]. From the perspective of the rabbis, Christianity is a religion, while Judaism is not, at least until the attempt of
Maimonides and especially until the time of Modernity, when the notion of 'Jewish faith' emerged." == Synagogal art ==
