Renan, E., Marc-Aurele et la fin du monde antique. Paris, 1882, p. 579: "On peut dire que, si le christianisme eût été arrêté dans sa croissance par quelque maladie mortelle, le monde eût été mithriaste."

Justin Martyr, First Apology, ch. 66: "For the apostles, in the memoirs composed by them, which are called Gospels, have thus delivered unto us what was enjoined upon them; that Jesus took bread, and when He had given thanks, said, "This do ye in remembrance of Me, this is My body; "and that, after the same manner, having taken the cup and given thanks, He said, "This is My blood; "and gave it to them alone. Which the wicked devils have imitated in the mysteries of Mithras, commanding the same thing to be done. For, that bread and a cup of water are placed with certain incantations in the mystic rites of one who is being initiated, you either know or can learn."
