On Ash Wednesday, February 18, 2026, nearly 400 prominent Christian leaders — including denominational officials, seminary presidents, theologians, and congregation leaders — released "A Call to Christians in a Crisis of Faith and Democracy," a public letter condemning the Trump administration as "cruel and oppressive" and accusing it of promoting "a Christian faith corrupted by the heretical ideology of white Christian nationalism." The letter warned that the United States was being pushed "toward authoritarian and imperial rule" and alleged that "citizens and immigrants [were] being demonized, disappeared, and even killed" as hard-won rights eroded. Signatories called on fellow Christians to commit to "greater acts of courage to resist." Cardinal Blase Cupich, Archbishop of Chicago, led a public Ash Wednesday Mass and procession in solidarity with immigrant communities targeted by the administration.
The letter directly named white Christian nationalism as a heresy — a striking theological claim that reframed the administration's appropriation of Christian identity as a corruption of the faith rather than an expression of it. It represented the most organized and theologically explicit collective religious response to the administration's Christian nationalist posturing, distinguishing between authentic Christian ethics and the weaponized version the administration deployed to justify immigration crackdowns, attacks on diversity, and authoritarian consolidation of power.
For the institutional capture timeline, the letter documents the growing rupture between the administration's claimed religious authority and the institutional church's judgment — a fracture that matters because the administration's Christian nationalist legitimation strategy depends on broad Christian assent. The public disagreement among clergy weakens the ideological cover that Christian nationalism provides for kleptocratic and authoritarian policy, while simultaneously illustrating the extent to which religious identity has been captured as a political tool.
