Corrections

Ad Fontes is about how texts change in transmission, so this online study tracks its own substantive corrections. Typographical fixes are not logged. When a correction may also affect the print edition of the book, it is identified as an erratum candidate for a future printing.

July 14, 2026 — Glossary

• Diatessaron. Corrected “the earliest known full New Testament reading text.” Tatian’s work is a harmony of the four Gospels, not a complete New Testament. (Erratum candidate for the print edition.)
• ECM (Editio Critica Maior). Clarified that each volume completely collates a representative selection of witnesses chosen after test-passage analysis of the wider tradition, rather than “all known manuscript witnesses.” (Erratum candidate.)
• NA28. Corrected an anachronism: the NASB95 followed NA26, while the ESV and NET followed NA27; NA28 succeeded NA27 in 2012. (Erratum candidate.)
• Text-types. Added the caution that Alexandrian, Byzantine, and Western text-type labels are historical generalizations rather than rigid genealogical families. (Clarification.)
