Researching for my Marcion video was actually pretty tough. Not because of the scarcity of sources, but because of the huge glut of scholarship on the topic. Marcion is pretty popular among scholars, and I needed to distill all of their research into a 10 minute video.
Coincidentally, I had just read a recent monograph on the topic: Dieter Roth’s The Text of Marcion’s Gospel. Roth’s book is so interesting because he tries to reconstruct Marcion’s version of the Gospel of Luke. If you remember from the video, Marcion is famous for “corrupting” the Gospel of Luke (or some other text that his detractors called a corruption of Luke). By mining the writings of authors like Epiphanius and Tertullian, Roth offers a plausible reconstruction of that Gospel. The book is quite technical and really requires an understanding of Latin and Greek, but I highly recommend it if you’re interested in the so-called “Marcionite Canon.”
