What the Epistle of Barnabas is (and what it isn’t)
The Epistle of Barnabas is an anonymous early Christian treatise in 21 chapters, written as an “epistle” by an author who presents himself as Barnabas. Modern scholarship generally treats that attribution as a literary claim rather than secure authorship. The work’s central move is interpretive: Israel’s scriptures and commandments are read as figures (types) that point to Christ and Christian ethics—especially in discussions of sacrifice, covenant, the cross, and practices like circumcision and food laws. Barnabas is also not a “lost gospel” and it isn’t preserved as a secret text; it is transmitted in standard manuscript contexts. One key guardrail: the fact that it appears after the New Testament in Codex Sinaiticus shows it was copied together with New Testament writings in that codex, but it does not demonstrate that any single church council “removed” it from the Bible.

Primary manuscript evidence: the two complete Greek witnesses
For readers who want to know what actually survives, the most important point is that the Epistle of Barnabas is complete in two independent Greek manuscripts.
First, Codex Sinaiticus (4th century) transmits Barnabas along with New Testament books and the Shepherd of Hermas; the project’s official site explicitly lists Barnabas among the codex’s contents. (codexsinaiticus.org) Second, an 11th‑century witness, Codex Hierosolymitanus, is dated by its scribe to 1056 CE and also preserves a complete Greek text of Barnabas—making it a crucial independent check on Sinaiticus for textual comparison.

A practical takeaway: most modern translations ultimately depend on these witnesses (directly or indirectly), and good editions keep their differences visible rather than silently conflating them.
Codex Sinaiticus: what its placement tells you (and what it can’t prove)
Codex Sinaiticus is a 4th‑century biblical manuscript whose surviving contents include the full New Testament, followed by two additional early Christian writings: the Epistle of Barnabas and the Shepherd of Hermas. The codex’s official “Content” description is explicit that these two texts appear beyond the New Testament collection in that manuscript. (codexsinaiticus.org)
This placement is historically meaningful: it shows that at least one major 4th‑century production context copied Barnabas together with New Testament writings, which helps explain why Barnabas mattered to later readers and why it remained continuously transmissible.
But the limits matter just as much. A codex table of contents is evidence for what that codex includes—not a universal statement about what every church everywhere regarded as scripture. Treat Sinaiticus as strong evidence for reception and circulation, not as a shortcut to claims of universal canon status.
Codex Hierosolymitanus (1056): why it’s a big deal for Barnabas
Codex Hierosolymitanus—often called the Jerusalem Codex—was completed in June 1056 CE and contains a cluster of important early Christian texts. In addition to Barnabas, it is famous for transmitting the Didache and for preserving Greek texts of 1–2 Clement, among other works. (cdn-static.supadu.com)
For Barnabas specifically, its value is straightforward: it gives us a complete Greek text that is independent from Codex Sinaiticus. That means scholars can compare readings between two full witnesses instead of relying on a single manuscript for the entire work.
For non-specialists, this should change how you read a modern English translation. When you see footnotes that mention variant readings, the most meaningful variants typically trace back to differences between these major witnesses (or between these and smaller fragments/versions).
How Barnabas argues: typology and a “re-read” of Torah practices
Barnabas is not mainly a narrative text; it’s an argument, built out of scriptural citations and interpretive claims. The author repeatedly insists that commandments and rituals—sacrifice language, covenant signs, food regulations, circumcision—should be understood in a deeper sense that points to Christ and to a Christian moral life. That is why the text can feel like a running commentary: the author moves topic-by-topic, treating laws and passages as symbols.
This approach also explains why Barnabas can sound sharp in its claims about Israel’s misunderstanding of scripture. Whether a reader finds Barnabas spiritually compelling or polemically troubling, the interpretive method is the heart of the book.
If you’re comparing Barnabas with other early Christian instruction, note that it closes with a “Two Ways” ethical section (light vs. darkness), a form also known from other early Christian catechetical traditions.
Date and authorship: what’s commonly said vs. what the manuscripts can prove
The manuscripts tell us what survives and (sometimes) when a particular copy was made; they do not directly identify the author or provide a composition date. With Barnabas, that gap matters.
Established from manuscript evidence: Barnabas was in circulation early enough to be copied into the 4th‑century Codex Sinaiticus, and it continued to be copied in Greek into the 11th century (Codex Hierosolymitanus). (codexsinaiticus.org)
Disputed interpretation: the precise date of composition (often placed somewhere in the late 1st or early 2nd century in secondary discussions), the author’s identity, and the work’s place of origin. Even older reference works acknowledge that early Christian writers differed in how they treated the text’s authority. (newadvent.org)
A careful reading strategy is to separate (1) what the text claims rhetorically (Barnabas’ voice) from (2) what we can historically demonstrate.
How to use this edition responsibly (translation as a historical reading text)
Because Codex ISO’s edition is presented as a historical reading edition (not a fresh critical collation), the safest way to use it is as a window into how Barnabas has been read in English, while keeping the manuscript situation in mind.
If you’re doing close study, prioritize these steps: (1) identify whether a statement you care about is stable across the major Greek witnesses; (2) watch for places where a translation smooths an ambiguity that the Greek leaves open; and (3) remember that damaged or variant readings are part of the text’s history.
