Scholarly work on Luke has often noted the significance of Marcion's Gospel for understanding the textual history of the third canonical Gospel. It is not surprising, therefore, that in the past new insights into Marcion's Gospel have led to revisions in the apparatus of the highly influential Nestle-Aland Novum Testamentum Graece, now in its 28th edition. In view of the precedent for continually updating the Nestle-Aland text and apparatus, this article revisits the apparatus to Luke in the light of recent research on Marcion's Gospel in order to highlight problematic references that should be changed or removed in the apparatus of future Nestle-Aland editions.
