When talking about the Qur’an with others, I like to ask “Is it an ancient text or a medieval text?” Most people will say ancient right away, but it does not fit nicely on either side. Muhammad died in 632, and so the text of his book was written in a period that is referred to as either late antiquity or the early middle ages. To give some context: In the West, St. Benedict has only decades ago written his rule which will give stability to Europe in the Middle Ages, and St. Isidore and St. Gregory the Great are wrapping up the era of the Church Fathers in the West. And yet these developments have no direct bearing on the Qur’an. When Muhammad refers to “Romans”, this refers to those who are living in Greece and Turkey, what history now refers to as the Byzantine Empire (and most translations of the Qur’an will just say “Byzantines” instead of “Romans”). In the Eastern Empire, the Patristic era has not yet ended. St. Maximus the Confessor will arrive around 650 to determine the Monothelite controversy, and then the following century will be concerned with the Iconoclasm controversy—a controversy that inspired (in part) by iconoclastic Muslim neighbors, but which is ultimately resolved (in part) through the writings of St. John of Damascus, who wrote under the protection of an Islamic patron.
