Who was responsible for writing the Zohar and was it only one person

Who Wrote the Zohar?

The authorship of the Zohar is one of the most debated questions in Jewish intellectual history. The traditional view attributes the Zohar to Rabbi Shimon bar Yochai (Rashbi), a 2nd-century Tanna, while modern scholarship largely attributes its composition to Rabbi Moshe de Leon, a 13th-century Spanish kabbalist — though even this view is nuanced, as the Zohar likely developed in layers involving multiple contributors.

Key Takeaways

The traditional view holds that Rabbi Shimon bar Yochai authored the Zohar while hiding in a cave, with its teachings transmitted orally until later.
Rabbi Moshe de Leon (13th century Spain) was the person who first circulated the Zohar publicly, and his wife reportedly admitted he wrote it himself.
Modern scholarship sees the Zohar as a composite work — likely authored or compiled primarily by de Leon, possibly with collaborators.
Some authorities, including critics cited in the sources, argued that the Zohar was written by a medieval philosopher-kabbalist, not an ancient Tanna.
The Zohar's sanctity and authority are accepted by the vast majority of traditional Jewish communities regardless of the authorship debate.

The Traditional Attribution: Rabbi Shimon bar Yochai

The dominant traditional position is that the Zohar was authored by Rabbi Shimon bar Yochai (Rashbi), who lived in 2nd-century Roman Palestine.

The Zohar itself presents this framework — its teachings are delivered as dialogues between Rashbi and his disciples, including his son Rabbi Elazar. We see this directly in the retrieved sources:

"Rabbi Shimon [who wrote the Zohar] said, 'Elazar, my son, stop talking lest the supernal hidden secret, which humans know nothing about, be revealed.'" [Zohar, Introduction 4:11]

This passage depicts Rashbi actively teaching mystical secrets to his son Rabbi Elazar — consistent with the traditional narrative that the Zohar records Rashbi's hidden teachings.

The Likkutei Etzot (collected teachings of Rebbe Nachman of Breslov) reinforces the traditional attribution:

"Rabbi Shimon bar Yochai, who wrote the Zohar, invested the Aramaic language with such sanctity that even other things written in Aramaic have the power to arouse you to God." [Likkutei Etzot, Torah Learning 71]

The traditional narrative holds that Rashbi composed (or dictated) the Zohar during his 13 years hiding in a cave from Roman persecution [based on Shabbat 33b], and that the text was preserved and only revealed centuries later.

The Historical-Critical View: Rabbi Moshe de Leon

The most significant challenge to traditional attribution comes from historical evidence pointing to Rabbi Moshe de Leon (c. 1240–1305) of Guadalajara, Spain.

The retrieved source from BePardes HaChasidut VeHakabbalah presents the key evidence:

"The answer that appears reasonable is: Rabbi Moshe de Leon composed both the main body of the Zohar and its additions. Evidence for this: Rabbi Moshe revealed it, he distributed it publicly, he sent pamphlets from it to wealthy patrons and received handsome payment; his wife testified that de Leon never copied his pamphlets from any book, but 'wrote what he wrote from his own mind and heart'; Rabbi Yitzchak of Acre investigated and testified about this matter; the 'Ra'aya Meheimna' (the ancient Moses) merges in many places in the Zohar with the author of the Zohar, whose name is also — Moses…" [BePardes HaChasidut VeHakabbalah, History of the Zohar, Part I, 4:2]

This is a remarkable piece of evidence — the wife of de Leon herself admitted he composed it independently. Rabbi Yitzchak of Acre, a contemporary kabbalist who investigated the matter personally, also appears to have concluded de Leon was the author (though his own account is ambiguous).

The Critical View: A "Philosopher-Deceiver"

The most polemical position comes from The Wars of God (Milchamot Hashem), which appears to be a rationalist anti-Zohar polemic. This work refers to the Zohar's author as "הפילוסוף הרמאי מחבר הזהר" — "the deceiving philosopher, author of the Zohar" — and levels serious accusations:

That the Zohar's author denigrated the Mishnah and Talmud, calling them derogatory names like "shifcha" (a maidservant) and "klipah" (a husk) [The Wars of God 6:18]
That the Zohar's doctrine of the Sefirot (divine emanations) contradicts true Jewish monotheism as understood by Rambam, Saadia Gaon, and Yehuda HaLevi [The Wars of God 7:3]
That the "new kabbalists" were led astray by this philosopher-author [The Wars of God 3:2]

This view represents a minority rationalist position that rejected the Zohar's authenticity and authority altogether.

Was It Only One Author? The Composite Theory

Most contemporary scholars — and even some traditional authorities — recognize that the Zohar is not a single unified text but a library of related works:

The Main Components of Zohar Literature:

Sefer HaZohar — the main body of the Zohar
Zohar Chadash — "New Zohar," printed separately
Tikkunei Zohar — 70 commentaries on the opening word of Genesis
Ra'aya Meheimna — "The Faithful Shepherd," a section with a distinct style
Midrash HaNe'elam — considered by some scholars to be an earlier layer

The BePardes HaChasidut source notes that de Leon composed "both the main body of the Zohar and its additions" — suggesting even proponents of de Leon's authorship recognized multiple textual layers.

Scholar Gershom Scholem, the preeminent modern researcher of Kabbalah, concluded that the Zohar was primarily authored by de Leon, but that the Ra'aya Meheimna and Tikkunei Zohar sections were composed by a different, slightly later author — meaning at least two medieval authors were involved.

Why Does This Debate Matter?

The underlying tension is theological and halachic (relating to Jewish law):

If Rashbi wrote the Zohar in the 2nd century, it carries near-prophetic authority and can even be used to adjudicate halachic questions.
Rabbi Yosef Karo (Beit Yosef) and the Vilna Gaon both ruled according to Zohar in various halachic disputes, treating it as an authoritative ancient source.
Rabbi Yitzchak bar Sheshet Perfet (Rivash, 14th century) already expressed doubts about the Zohar's antiquity, noting it contained apparent errors about Talmudic figures.
If de Leon wrote it in the 13th century, it is still a profound work of mystical theology — but its halachic weight is considerably diminished.

The Mainstream Traditional Conclusion

Despite the historical debates, the overwhelming consensus of traditional Jewish authorities — Sephardim, Ashkenazim, and Hasidim alike — accepts the Zohar as a sacred, authoritative text associated with Rabbi Shimon bar Yochai's tradition. The Ari (Rabbi Yitzchak Luria) built his entire Kabbalistic system on the Zohar. The Beit Yosef, Ramak (Rabbi Moshe Cordovero), and virtually all subsequent mystical tradition treat it as ancient and holy.

Even those who privately doubted its authorship — like the Chatam Sofer, who reportedly held nuanced views — did not publicly challenge its sanctity, given its deep acceptance throughout the Jewish world.
