In my judgment, the kabbalists hidden behind the personae of the zoharic fraternity sought to divest Christological symbols of their Catholic garb and redress them as the mystical truths of Judaism.

Much that is to be found in the Zohar was intended to serve as a counterweight to the potential attractiveness of Christianity to Jews, and perhaps even to the kabbalists themselves.

Appreciating the linkage between these two quotations and Jewish kabbalah requires the reader already know and acknowledge the degree to which Jewish kabbalah tends to transcend normative Jewish orthodoxy by leaps and bounds when it comes to the task of seeking a comprehensive theological basis for the whole of the Tanakh. This kabbalistic transcending of more general Jewish orthodoxy occurs in the sense of seeking and finding comprehensive answers to the myriad unanswered and unanswerable questions that arise whenever orthodox Jewish sages exegete the Tanakh in the traditional manner of not seeking a comprehensive center, or so called "transcendental-signifier," that all scripture is assumed to lead to, and which consequently leads to the overarching meaning of all scripture.
Since for Christians, Christ is the transcendental-signifier of the entire scripture, and since Isaiah chapter 53 therein acts something like a transcendental-signifier of Christ, as the transcendental-signifier of the entire scripture (since Isaiah 53 more that any other chapter in the Tanakh lends itself to Christian interpretation, interpolation, and or retrospective re-interpretation), Isaiah 53 is thus ground-zero for a Jewish movement, Jewish kabbalah, inspired (by the comprehensiveness of the Christian kerygma) to present a comprehensive, significant, transcendental, synthesis of Jewish learning worthy of being thought of as Jewish theology.
The Shelah is a consummate scholar who demonstrates mastery in every aspect of rabbinic learning, to wit, halakah and talmudic jurisprudence, homiletics and biblical exegesis, philosophy and ethics, and above all else the esoteric traditions known as Kabbalah. Horowitz combines an extensive knowledge of talmudic-halakhic Judaism and kabbalistic lore and thereby forges a synthesis that he presents as the basic reality of Jewish religiosity.
