Gennadius of Marseilles

• Ecclesiastical historian. Presbyter of Marseilles.
• If we accept his de Viris Illustribus (Lives of Illustrious Men), we are warranted in classing Gennadius of Marseilles with the Semi-Pelagians, as he censures St. Augustine and Prosper and praises Faustus.
• Moreover, the very laudatory account of St. Jerome at the commencement of the book seems inconsistent with the hostile reference to that father under the art.
• He was still living at the time of Pope Gelasius (492-496).
• He was the author of a great number of heresiological works.

• He continued Jerome’s patristic biographies - the de Viris Illustribus. This work, in its most commonly accepted form, was probably published ca. 495, and contains short but accurate biographies of ecclesiastics between 392 and 495, in 101 chapters.
• A treatise, entitled Epistola de Fide meâ, or de Ecceliasticis Dogmatibus Liber, begins with a profession of faith in the three creeds, interwoven with the names of those who are considered by the writer to have impugned this or that article of belief.
• He wrote eight books Against all the Heresies, five

Against Nestorius, ten Against Eutyches, and three Against Pelagius.

• Homilies on the Millenium and St. John’s Apocalypse.
