Atheist Michael Newdow says he'll ask a federal court to order removal of the national motto "In God We Trust" from U.S. coins and currency.
He says it violates the religious rights of atheists who belong to his "First Amendment Church of True Science."
The church's "three suggestions" are "question, be honest and do what's right."
Newdow says it wouldn't be right to take up a collection when the money says "In God We Trust."
Last year, the Supreme Court dismissed Newdow's lawsuit over the words "under God" in the Pledge of Allegiance because he doesn't have custody of his daughter, in whose name the lawsuit was filed.
Newdow has resurrected that case by filing an identical lawsuit on behalf of two families.
Word of the suit came on the same day the U.S. Supreme Court declined to take up a dispute over whether it's appropriate to put "In God We Trust" on government buildings.
The court rejected an appeal about the inscription on a government center in Lexington, N.C.
The court didn't comment on its ruling.
An appeals court had ruled the phrase was patriotic, appearing on the nation's coins and made the national motto by Congress, but an attorney for opponents of the inscription told justices the statement is a religious creed.
Earlier this year, justices were divided on the appropriateness of Ten Commandments displays in and near government buildings.
