Albrecht Ritschl’s Das Evangelium Marcions und das kanonische Evangelium des Lucas: Eine kritische Untersuchung (Tübingen: Osiander’sche Buchhandlung, 1846) is eight preliminary pages, 301 pages of text, and an unnumbered leaf of corrections. It is the book in which he argues that Marcion’s Gospel is the earlier writing and that canonical Luke is a later revision of it.
A search on 27 September 2026, against the German title, the English title, library and facsimile records, and the scholarship that cites the book, did not locate a complete English translation. That search is not a proof that none exists. What does exist, and is not this book, is the German original, German facsimile reprints, English scholarship that summarizes the thesis, and English translations of other works by Ritschl.
What follows is Ritschl’s 1846 book, with his notes and the page numbers of that printing. His later change of mind is not in these pages. Later reconstructions, modern critical texts, and the True Testament do not silently correct him. Greek and Latin remain as he printed them.
