The Eastern Orthodox Church includes broader scriptural texts including deuterocanonical materials in its biblical canon. The Orthodox tradition received the Old Testament through the Septuagint, which incorporates texts not found in the Hebrew Bible, including Tobit, Wisdom, Sirach, 1 and 2 Maccabees, and additions to Daniel and Esther. These are affirmed as Scripture within the Orthodox Church.

The Eastern Orthodox approach to canonicity reflects the role of the Septuagint in early Christian tradition and the consensus of the ecumenical councils. While the Church recognizes historical distinctions between different categories of biblical texts, the deuterocanonical books are included in the Orthodox biblical canon and cited in the Divine Liturgy and theological teaching. The Church's reception of these texts through patristic and liturgical tradition substantiates their canonical status. This reflects the Orthodox principle that Scripture's authority is authenticated through the Church's living tradition and the witness of the seven ecumenical councils.
