📘 The Biblical Canons: A Side‑by‑Side Overview


1. What Is a “Canon”?

The word canon means “rule” or “standard.”
In Scripture, it refers to the set of books recognized as inspired and authoritative for faith and practice.

Scripture Notes:

  • “All scripture is given by inspiration of God…”2 Timothy 3:16
  • “…holy men of God spake as they were moved by the Holy Ghost.”2 Peter 1:21

2. Why Do Different Traditions Have Different Canons?

The Old Testament was transmitted through different historical communities:

  • Jewish communities preserved the Hebrew Scriptures (Tanakh).
  • Early Christians used the Septuagint, a Greek translation containing additional books.
  • Church councils in the 4th–16th centuries affirmed different collections based on tradition, language, and usage.

The New Testament, however, is the same across all major Christian traditions.
