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

Biblical Unitarians, like most Protestants, do not regard the deuterocanonical books (Tobit, Wisdom, Sirach, Baruch, 1 and 2 Maccabees) as part of the biblical canon, though they value these texts as important historical and spiritual sources from Second Temple Judaism. The books were not included in the Hebrew canon, do not appear in the earliest Greek New Testament manuscripts as authoritative Scripture, and are explicitly rejected by major Reformation figures and Protestant confessions.

Biblical Unitarians note that Jesus and the New Testament authors consistently cite from the Hebrew Bible (the 39 books of the Protestant Old Testament) but never cite the deuterocanonical books as Scripture. While these works provide valuable context for understanding First-century Jewish thought and are historically important, they are not considered part of the apostolic witness or the biblical foundation of Christian doctrine. This view aligns with the classical Protestant principle of sola scriptura applied to the canon of the Hebrew and Greek Testament scriptures.
