Documentary Hypothesis, as expressed by the Graf-Wellhausen theory, with his arguments presented in the work Die wichtigsten Instanzen gegen die Graf-Wellhausensche Hypothese (1903/1916). A. Altmann, however, sees Hoffmann's writings on these matters (though evidencing great expertise) as pure apologetics, the cause of which may be seen as laid out in his introduction to Leviticus , where Hoffmann makes the following remarks: Yet, despite the piety of the above sentiments, and his repeated proclamations regarding the divinity of the Oral Law, Hoffmann was still very much the Wissenschaft scholar. He cites in his work scholars such as Z. Frankel, A. Geiger, S.J. Rapoport, and H. Graetz, he studies the influences of Ancient Near Eastern culture on the evolution of the Talmud, and he identifies problems in the transmitted text. For example, Hoffmann in The First Mishna (discussed below) sees the present Mishna Avot as having been redacted from three different sources, a Mishna of Rabbi Akiva, a Mishna of Rabbi Meir, and a Mishna of Rabbi Judah Ha-Nasi, the originals of which cannot be completely reconstructed due to their thoroughgoing fusion and subsequent manipulation. The extent to which Hoffmann resided in the Wissenschaft movement can also be seen from the criticism he received from such opponents of the movement as Samson Raphael Hirsch. Hildesheimer notes regarding Hirsch's opinion of his Rabbinical Seminary (where Hoffmann worked after leaving Hirsch's institution) that "a question certainly exists as to whether Rabbi Hirsch considers the seminary to be an Orthodox institution." Hirsch's opposition extended to Hoffmann's own work, judging Hoffmann's book Mar Samuel to contain heresies . Hoffmann's resolution of this tension between faithfulness to tradition and textual criticism is found by in the following passage from the introduction to The First Mishna: Writings Hoffman produced the Die Erste Mishna (The First Mishna), mentioned above, a historical and linguistic analysis of the Mishnah. Die Erste Mishna posits an early, uniform, undisputed, and therefore authoritative collection of the Oral Law, attempting to understand the historical development of the Mishnah from within itself and from rabbinic and non-rabbinic sources related to it. In this and the below work, Hoffmann draws on his expertise in midrash halakha and Semitic languages. For further context, see Oral Torah #In rabbinic literature and commentary. His commentary on the Pentateuch that included a translation of the text into German, is still widely cited. In it, he addresses erstwhile biblical criticism, particularly questions
