Deuterocanonical Books — "Tobit, Wisdom, Sirach, Maccabees"

Eastern Catholic Churches include the deuterocanonical books in their biblical canon in accordance with the broader Catholic tradition. These texts—Tobit, Wisdom, Sirach, 1 and 2 Maccabees, and portions of Daniel and Esther—are affirmed as Scripture and are cited in the Divine Liturgy, theological teaching, and pastoral practice. The Eastern Catholic approach combines Eastern Orthodox liturgical and theological sensibilities with the Roman Catholic definition of the biblical canon.

Eastern Catholic Churches, while maintaining Eastern Orthodox traditions in liturgy and theology, remain in communion with the Roman Catholic Church and thus follow the Catholic canon that includes the deuterocanonical books. These texts are valued for their historical accounts, spiritual wisdom, and their role in the Church's lived Tradition. The inclusion of the deuterocanonical books reflects the Eastern Catholic commitment to the fuller biblical tradition that encompasses both Palestinian and Hellenistic Jewish sources, as preserved in the Septuagint and the patristic consensus.
