Reform Judaism

Lore & Background

Understanding Judaism through the historical-critical method and modern philosophy, the early Reform movement sanctioned conscious adaptation of religious life, omitting observances and beliefs considered irrelevant or superstitious. In the public sphere, it removed parts of the liturgy pertaining to concepts like bodily resurrection and the restoration of the sacrificial cult, and translated much of the prayer from Hebrew to the vernacular German. In the private sphere, it condoned the widespread abandonment of personal observance of dietary, Sabbath, and other ritual laws.

Reader's Guide

Reform Judaism's significance lies in its radical redefinition of Jewish identity and practice, prioritizing ethical aspects over ceremonial ones and individual autonomy over communal law. Its early 'Classical Reform' phase in the United States, flourishing from the 1860s to the 1930s, adopted a universalist approach with little place for Jewish particularism, disposing of most traditional practice. Since the 1970s, the movement has adopted a policy of inclusiveness and acceptance, becoming extremely diverse and strongly identified with progressive and liberal agendas, mainly under the rubric tikkun olam ('repairing of the world'). This shift, termed the transition from 'Classical' to 'New' Reform, favored personal spiritual experience and communal participation over coherent theology, drawing large crowds but also drawing criticism that Reform became more of a Jewish activities club than a defined belief system. The movement's inherent pluralism and emphasis on individual autonomy impede any simplistic definition.

Did You Know?

• The Shema prayer, central to Judaism, is commonly translated as: 'Hear O Israel: the LORD is our God, the LORD is One' (Deuteronomy 6:4).
• Jews traditionally do not pronounce the Tetragrammaton (YHWH), substituting HaShem ('the Name') in speech and Adonai ('My Lord') in prayer.
• The Torah specifically forbids ascribing partners to God's singular sovereignty, and the idea of a duality or trinity is considered akin to polytheism in Judaism.
• In Judaism, God is never portrayed in any image, and is understood to be similar to nothing and nothing is comparable to him.
• Some modern interpretations of Judaism emphasize God as an impersonal force or ideal rather than a supernatural being concerned with the universe.

The Shared Abrahamic Foundation

Every major Abrahamic faith—Judaism, Christianity, Islam, Samaritanism, the Druze path, the Baháʼí Faith, and the Rastafari movement—rests on a single bedrock conviction: there is one God, the deity who spoke to Abraham in the ancient narratives. This shared God is described across these traditions as eternal, all-powerful, all-knowing, and the origin of the entire cosmos. He is simultaneously transcendent, existing beyond the boundaries of space and time so that nothing within creation can constrain him, and deeply personal, bending close enough to hear an individual's whispered prayer and to respond to the moral choices of his creatures. The theological vocabulary of each of these faiths carries the imprint of the God of Israel as portrayed in the Hebrew Bible, explicitly named YHVH in Hebrew and rendered as Allah in Arabic. All of these communities trace their spiritual or genealogical lineage back to Abraham as a common patriarch, and all affirm God's holiness, justice, boundless benevolence, and presence everywhere at once. Despite their later divergences, this common monotheistic architecture remains the defining feature that sets the Abrahamic family apart from other religious traditions.

Judaism's Indivisible Oneness

Judaism, the eldest of the Abrahamic faiths, anchors itself in a strictly exclusive monotheism that finds no room for partners, equals, or intermediaries. The divine being is venerated solely as Yahweh, the name rendered in the Hebrew Bible as the four-letter Tetragrammaton (YHWH) or as Elohim. Out of reverence, Jews traditionally avoid pronouncing the sacred name, substituting HaShem—literally 'the Name'—in everyday speech, or Adonai, 'My Lord,' in prayer. The Shema, drawn from Deuteronomy, crystallizes this conviction in a single declarative sentence: the LORD is Israel's God, and the LORD is One. Within this framework, God is conceived as absolutely unique, flawless, and infinite in every attribute—omnipotent, omnipresent, omniscient—without any second, without any division. The Torah explicitly forbids ascribing any co-sovereign to this singular being. Any suggestion of duality or trinity is treated as heretical, effectively equivalent to polytheism. God is never depicted in any visual form, and is understood to be beyond all human thought and expression, similar to nothing in the world and comparable to nothing else.

A God Who Speaks and Listens

Within Jewish theological tradition, the divine being is not an abstract principle floating apart from the world. God is described as anthropomorphic in the sense of possessing a will, as benevolent, as eternal, and as the ultimate wellspring of all moral order. The term 'God' in this context points to a genuine ontological reality rather than a mere projection of the human mind. Traditional interpretations stress a God who is both personal and transcendent: one who reaches into the fabric of the world, intervenes in history, listens to the prayers of individuals, and responds to the deeds of his creatures. Yet this personal engagement coexists with a radical transcendence. God exists outside of space and time, subject to nothing within his own creation. He is the sole creator of everything that exists, free from every fault, deficiency, or limitation. In more recent interpretive currents within Judaism, however, some thinkers have shifted the emphasis, portraying God less as a supernatural personality concerned with the universe and more as an impersonal force or ideal. This spectrum—from the intimate, intervening deity to the boundless, non-personal ground of being—reflects the ongoing conversation within Jewish thought about how to hold together God's closeness and God's incomparability.

The Line of Distinction

The clearest theological boundary separating Judaism from its Abrahamic siblings runs through the question of divine plurality. Christianity, which emerged in first-century Judea from a strand of apocalyptic Jewish Christians, inherited much of the Jewish God-conception—omnipotence, omniscience, creatorhood, personality, immanence, and transcendence—yet introduced a decisive innovation: the identification of Jesus of Nazareth as the fulfillment of messianic prophecy, the completion of the Mosaic Law, the Son of God, and in many denominations, the incarnation of God in human form. Mainstream Christian theology, codified at the Council of Nicaea and enshrined in the Nicene Creed, articulates this through Trinitarianism: three distinct persons sharing one indivisible essence. Judaism regards any such multiplicity within the Godhead as fundamentally incompatible with its exclusive monotheism. The Torah's prohibition against ascribing partners to the singular sovereign is absolute, and the idea of a Trinity is classified as heretical, tantamount to polytheism. From the Jewish perspective, belief in an intermediary between humanity and God, or in multiple persons within the divine, contravenes the foundational demand that God remain the absolute, indivisible One. This single point of divergence shapes the entire theological landscape that separates the two traditions.
