On Sunday, May 17, 2026 (Monday morning, May 18, for Australians), tens of thousands of Americans will gather on the National Mall in Washington D.C. for the first-ever rededication of the USA as one nation under God. Here’s what’s scheduled to take place and the Christian leaders headlining this historic occasion.

Johnson wrote in his open letter of invitation to the national gathering: “This is a unique moment for believers. For the first time in modern history, a U.S. president has called our nation to prayer — to humble ourselves and to rededicate America to God. “This will be the first time that Americans will gather together to rededicate the United States as One Nation Under God.

“Through worship, prayer, and storytelling, we will remember the people, sacrifices, and foundational moments in which God has shaped our history. By the end, I hope you will see the truth in Benjamin Franklin’s famous admonition: ‘that God governs in the affairs of men.’”

The speaker list features multiple well-known American Christians, from Jonathan Roumie (beloved by millions for his portrayal of Jesus in The Chosen), to evangelist Franklin Graham and Grammy-winning worship artist Chris Tomlin. Notably, the event bridges Protestant and Catholic traditions, with both Cardinal Timothy Dolan and Bishop Robert Barron participating alongside evangelical leaders.

According to Pastor Robert Jeffress — who is scheduled to speak at the event — Rededicate 250 could be the largest Christian gathering in 50 years.

Jeffress was referring back to Explo ‘72, a 1972 Campus Crusade for Christ conference attended by over 80,000 college and high school students in Dallas, at which the late evangelist Billy Graham preached. For context, Explo ’72 is widely regarded as one of the most significant Christian gatherings in American history, which some say marked the height of the Jesus Movement. This makes Rededicate 250’s potential scale all the more remarkable.

Event officials have written that the purpose of Rededicate 250 is to “gather in prayer, worship, and storytelling and to rededicate our country as One Nation Under God.”
