Maximus the Confessor: The Byzantine official and monk who warned and witnessed the….JEWISH-MUSLIM ALLIANCE against…CHRISTIANITY!!!
Maximus the Confessor (c. 580–662), a Byzantine official and monk, witnessed the early Islamic conquests firsthand. What is striking is not just his fear—but how he describes what he saw. He does not portray it as a simple Arab invasion. Instead, he speaks of a “Jewish–Arab” convergence, in which Jewish communities were part of the advancing forces. His tone is hostile and apocalyptic, but beneath that rhetoric is a historical observation that deserves to be taken seriously.
Why would a contemporary Christian observer describe the conquest this way?
One possibility—echoed in modern scholarship such as Fred Donner’s Muhammad and the Believers—is that the earliest movement around the Prophet ﷺ was not yet a rigidly defined “Islam” in the later sense, but a broader community of Believers, centered on pure monotheism, divine law, and moral accountability. In that early phase, the lines between Jews and the emerging Muslim community may have been far more porous than later theology would allow. From the outside, especially from a Byzantine perspective, the distinction may have been nearly invisible.
What Maximus calls a “Jewish–Arab army” may therefore reflect not just political convenience, but a deeper reality: a moment in which Jews and early Muslims could still recognize one another as participants in a shared Abrahamic project—a project defined by law, scripture, and rejection of imperial Christian theology. This would explain why some Jewish communities appear to have welcomed the new order, and why early Islamic discourse continues to engage Banī Isrāʾīl as an ongoing religious community, not merely a relic of the past.
From this angle, the early conquests begin to look less like the birth of a completely new religion, and more like the reconfiguration of an existing religious world—one in which older alignments briefly resurfaced before hard boundaries were drawn. What later became two distinct traditions may, at this early stage, have functioned as overlapping expressions of a single monotheist revival.
Maximus, of course, could not accept this. For him, the collapse of boundaries between Jews and the new Arab movement was not a sign of continuity, but of crisis. That is why he reaches for the language of Antichrist. But in doing so, he unintentionally preserves a memory of something that later histories obscure: a time when the divide between Judaism and the emerging Islamic movement was not yet absolute, and when cooperation between them was visible enough to alarm the Byzantine world.
It is also worthy of note that the Antichrist demonology expressed has been co-opted by some Muslims against Jews today.
Sometimes the most revealing testimony comes from those who opposed what they were witnessing.
Letter 14 Describing the “Jewish Arab” army of the early Islamic conquests.
“But I remind you [Christians], who are guarded by God, to be vigilant and pray according to the command of the Lord that we will not be overcome by the snares of all the temptations that surround us from every side. For if we are vigilant and sober, I know that we will guard ourselves against the tricks of the demons. And if we pray, we will gain for our aid the divine grace that battles along with us and makes us victorious against every opposing power and protects us from error and ignorance. This is especially what we must do now, when, even without a command, nature, taking into account the circumstances, teaches us to seek refuge in God. For what is more precarious than the evils that beset the world today? What is more terrible to those who understand than the things that are happening?
What is more pitiable or fearsome for those who endure them? To see this barbarous people from the desert overrunning another’s lands as if they were their own! And to see this civilized polity devoured by savage and raging beasts, who have the mere appearance of only the form of a human beings! And to see the Jewish people, who have long delighted in the flow of human blood and know only how to please God through slaughter of a creature, who because of this are filled with rage to be more conspicuous in wealth of wickedness than those acclaimed for iniquity, who think that they serve God by doing what is hated by God, who alone are the most faithless of all the peoples on the earth. And therefore they are most ready to welcome the enemy forces, ushering in, by every way and means, the advent of the evil one, and revealing by what they are doing the arrival of the Antichrist, since they ignored the true Savior.”
