Breuer's position was that only a single correct text of Tanakh existed; any variants from this authoritative edition were therefore errors.

Breuer's approach to establishing this correct text and punctuation of Tanakh was at first eclectic, based on several early manuscripts (and the Venice edition of Mikra'ot Gedolot) and their masoretic notes, as well as notes from Wolf Heidenheim and Minḥat Shai (Rabbi Solomon Norzi).

He later gained access to the Aleppo Codex (dating from the tenth century) and found it to match almost perfectly with his work, supporting his thesis of only one correct edition.

It is based graphically on the Aleppo Codex, and is now the official Tanakh of the Hebrew University of Jerusalem and of the Israeli Knesset.

If applied, this approach would provide an alternative framework to the documentary hypothesis, which maintains that the Torah was written by multiple authors.

[2] In his two volume book Pirkei Moadot (1986), Breuer discusses twenty eight topics, mostly holidays like Shabbat, Pesach, Shavuot, and Hanukkah.
