In the spring of 6 CE, a Galilean teacher named Judas stood against the Roman census and declared that God alone was master of Israel — that paying tribute to Caesar was not merely a political inconvenience but a betrayal of the covenant that gave Jewish existence its meaning. His declaration sparked a movement that would burn for a hundred and thirty years, consuming everything it touched and transforming a people in ways that are still visible in the world today.No Master But God traces the full arc of Jewish resistance against Rome, from the consolidation of Herod the Great's client kingdom through the catastrophic Bar Kokhba revolt of 132–135 CE. It follows the dynasty of resistance fighters that Judas of Galilee founded — through his crucified sons, his messianic grandson, and the kinsman who organized mass suicide at Masada rather than submit to Roman capture. It reconstructs the siege of Jerusalem, the burning of the Temple, and the systematic Roman attempt to erase Jewish identity from the landscape of Judaea itself.Drawing on Josephus, rabbinic literature, Roman administrative records, and the extraordinary letters of Bar Kokhba discovered in the Judaean desert caves, Conrad Brennan delivers a narrative of faith, resistance, and catastrophe that speaks directly to what it costs to believe something completely — and what survives when belief outlasts the world that produced it.
