At the heart of Karaite self‑definition is a claim that the Hebrew Bible (Tanakh) alone constitutes authoritative revelation for communal law and belief. Karaites describe themselves as 'scripturalists': they undertake halakhic and theological reasoning directly from the text of Torah, Prophets and Writings, employing philology, contextual reading and appeals to literal sense. This claim is not monolithic; among Karaites there are diverse hermeneutical schools and emphases, but the shared presupposition — rejection of the rabbinic Oral Torah (Mishnah, Talmud, and later rabbinic codes) as normative binding law — is the defining doctrinal boundary between Karaism and rabbinic Judaism.
Adherents hold that the divine communication recorded in the Hebrew Bible supplies both narrative theology (God’s relation to Israel and history) and normative commandments. Consequently, Karaites typically emphasize the plain sense (peshat) and grammatical‑historical exegesis; they often appeal to context, comparative lexical study, and historical‑geographical considerations in order to render a text’s obligation in life and law. For example, where rabbinic tradition might consider an action forbidden or required because of a Talmudic ruling, Karaites will look for a direct biblical injunction or an interpretive argument grounded in grammar and immediate context.
This scripturalism produces particular theological contours. On cosmology and God’s nature Karaites share core monotheistic commitments with Rabbinic Judaism: God is the singular creator, moral lawgiver, and object of worship. Karaite writings such as Aaron ben Elijah’s Etz Hayyim engage questions of divine attributes, providence and human responsibility in ways that parallel medieval Jewish philosophy, while retaining distinct emphases born of scriptural exegesis. Theological discussions about prophecy and the authority of later scriptural books (for example, the role of the Prophets in interpreting the Torah) play out differently in Karaite discourse because the interpretive horizon centers on Scripture itself rather than an evolving oral jurisprudence.
Ethically, Karaites tend to emphasize personal responsibility for complying with commandments as understood from the Bible. Practices of repentance (teshuvah), charity, and communal responsibility are present, though their precise form derives from scriptural injunctions as read within each community’s interpretive tradition. Thus, for example, laws about ritual purity, offerings, and festival observance are grounded in a direct reading of biblical passages and debates among Karaite jurists rather than the rabbinic corpus.
A central locus of difference — and ongoing intercommunal tension — is the status of legal precedent and the possibility of communal innovation. Rabbinic Judaism operates with a legal system that regards the Mishnah and Talmud as authoritative layers of interpretation which constrain later innovation. Karaism allows for a greater role for reasoned interpretation from the biblical text, and for communal adjudication by locally recognized scholars. This creates a tension: to rabbinic authorities, Karaites appeared to reject centuries of jurisprudential experience; to Karaites, rabbinic reliance on the Oral Torah represented an unauthorized accretion.
Karaite theology also includes particular stances on ritual matters that are rooted in scriptural readings. Calendar determination (the timing of months and festivals) is one such example: many Karaites have historically relied more heavily on local moon observation and agrarian signs than on the fixed calculated calendar adopted by rabbinic communities; this has produced divergent festival dates that remain a visible sign of difference. Another example is the approach to sacrificial laws and Temple‑related commandments: Karaites interpret these primarily as obligations tied to the biblical text, with discussions about their present applicability shaped by historical conditions and textual exegesis.
The Karaite canon is the same Hebrew Bible as used by other Jewish groups; Karaites do not, as a rule, add distinct scriptural books. Where divergence appears is in the status of scriptural interpretation: certain late‑composed liturgical poems and communal practices are accepted because they are argued from Scripture. Karaite literature includes medieval theological treatises and legal codes — Etz Hayyim and Aderet Eliyahu are two named works — that function as interpretive authorities in many communities. Thus Karaism combines a strict scriptural standard with an institutionalized body of secondary literature that guides practice.
Diversity within Karaism is substantial. Historians and contemporary observers distinguish among Levantine Karaites (with roots in Jerusalem, Egypt, and Syria), Crimean and Turkish communities (which developed different liturgical melodies, communal hierarchies and social strategies), and modern diasporic variants. These groups differ on matters such as the role of custom, the linguistic medium of prayer (Hebrew, Karaim dialects, Arabic, Turkish), and the valuation of certain medieval authorities. The existence of these diverging practices demonstrates that the doctrine 'Scripture alone' accommodates plural interpretive frameworks in practice.
Karaite eschatological and messianic ideas generally resemble mainstream Jewish expectations — belief in future vindication, resurrection (in many but not necessarily all Karaite formulations), and restoration — but the theological elaboration often stems from literal readings of prophetic texts rather than rabbinic elaboration. Similarly, metaphysical or philosophical debates (on the nature of angels, free will, and divine justice) are conducted in the same intellectual corridors as medieval Jewish philosophy but always anchored to scriptural exegesis.
Finally, the Karaite worldview includes a self‑conscious identity politics: adherents frequently describe themselves as restoring an earlier, purer reading of Scripture and of Israelite religion, a claim that places them in continuity with the biblical past while setting them in instructive tension with rabbinic Judaism. That tension, present since the tradition’s earliest centuries, shapes theological formulations, ethical emphases, and communal memory in ways that remain vibrant in contemporary Karaite thought.
