Is it fair — or even biblical — to apply the word "antichrist" to a political movement? Visiting scholar Matthew D. Taylor (Georgetown University) answers that question from scripture and history. In this conversation, I sit down with Matthew Taylor, author of Defying Tyrants: Following Jesus in a World of Christian Antichrists, to explore one of the most uncomfortable questions in American Christianity today: when does a Christian movement begin to exhibit the spirit of antichrist? Taylor's answer draws on New Testament scholarship, the parable of the wheat and tares, and a deeply inconvenient argument — that the history of Christianity, from Constantine forward, is in part a history of Christians abusing power in Jesus's name. That's not a fringe claim. It's a scholarly one with serious biblical grounding. This is not a political hit piece. Taylor is careful, precise, and anchored in the text. But the implications for Christian nationalism are impossible to avoid. If Christians can be the persecutors — not just the persecuted — what does that mean for movements wrapping authoritarian power in a cross?
