The Mishnah Rule That Guards the Oneness of God

There is a rule in the Mishnah that seems, on the surface, almost absurdly strict: if someone says “Modim, Modim” during the Amidah prayer, we silence them immediately (Berakhot, Chapter 1). Not gently. Not after a conversation. We silence them on the spot.

The word Modim means “we give thanks” and is the opening word of one of the central blessings in Jewish prayer. Saying it twice looks like enthusiasm. Looks like emphasis. What could possibly be wrong with giving thanks twice to God?

The answer, preserved in a text from The Wars of God, is that it can appear as if there are two authorities. Two divine powers receiving your gratitude. The Mishnah in Megillah says the same rule applies to “Shema, Shema”: saying “Hear, O Israel, the Lord our God, the Lord is One” twice in quick succession sounds like you are proclaiming two Lords rather than the One whose singularity the Shema is designed to assert. You cannot say “One, One” without implying that the ones you are counting are separate.

The Talmud in Berakhot 14a goes even further. Someone stood before Rava and said “Emet, Emet,” truth, truth. Rava was displeased. Truth, he said, cannot be doubled. Truth is singular. To say it twice is to suggest that you are holding two truths, which means neither of them is complete. The same logic applies to “One, One”: if you need to say it twice, the oneness you are proclaiming has already broken into pieces.

This is the point at which the text takes a sharp and dizzying turn.

The Zohar, in the section on Genesis, interprets the phrase “The Lord is King, the Lord was King, the Lord will be King forever” as referring to different aspects of the divine: the Father and Mother, the present configuration, the small and feminine. Three configurations, three divine faces, all crowned simultaneously by a single proclamation. If that is what the Zohar means, then God is being addressed in at least three different modes within a single sentence. Which one is the true king? Which one receives the gratitude of Modim?

The text quotes Rabbi Ba’al Ha’ikarim, who issued a serious warning against studying the Zohar without proper grounding in traditional learning. Not because the Zohar is wrong, but because without a teacher and without a firm foundation in the basic structure of Jewish theology, the Zohar’s language of multiple divine faces can look exactly like what the Mishnah was trying to prevent: the appearance of multiple powers, multiple addresses for human prayer, multiple destinations for the single name of God.

The tradition of warning seekers about Kabbalah without guidance runs throughout the mystical literature. The danger is not the material. The danger is the lens. Someone who reads the Zohar’s language of sefirot and partzufim, divine faces and configurations, without understanding that these are all descriptions of a single God engaging with creation through different modes, will come away thinking they have found evidence for exactly what the Shema denies.

The Mishnah’s rule about Modim is doing protective work. It is not a quirk about prayer etiquette. It is an enforcement mechanism for the most fundamental commitment of Jewish theology, the absolute unity of God, a unity so complete that even the appearance of multiplicity in a single prayer word demands immediate correction.

Say it once. Say it fully. Let the single word carry all the gratitude you have. If the word needs to be doubled to feel like enough, the problem is not with the word. The problem is with the expectation that theological sincerity requires repetition. In Jewish prayer, as in Jewish theology, one is enough. One is everything. The whole tradition exists to protect that one.
