With Vice President JD Vance calling Charlie Kirk “a martyr for Christianity,” some Kirk admirers suggest his assassination will galvanize throngs of people — notably young conservatives — to become more engaged in evangelical and Catholic churches. Evocations of Kirk-inspired religious fervor surfaced almost immediately after his death on Sept. 10, and continued to swell as much of Sunday’s VIP-studded memorial service for the conservative activist resembled a massive megachurch service. There have been widespread reports of attendance surging at some evangelical churches. But a religious demographics expert says any surge might be brief, given there are no recent examples of an enduring religious revival after a civic trauma.
