1 John 5:7-8 — "The Comma Johanneum"

Lutheran theology recognizes that the Comma Johanneum (1 John 5:7-8) does not appear in the earliest Greek manuscripts and was likely added later as a trinitarian clarification. However, Lutheran Bibles include the passage (often with textual notation), and Lutheran theology affirms the trinitarian content as consistent with biblical and creedal teaching. The doctrine of the Trinity itself is unquestionably affirmed in Lutheran faith; the textual status of this particular verse is less certain.

Lutheran tradition values the passage for its explicit trinitarian statement, even while acknowledging the manuscript evidence. Luther himself accepted various readings and translations that affirmed the Trinity. LCMS and Lutheran practice includes this passage as Scripture, though textually-aware.
