Persistent pressure and criticism have prompted the Church of Jesus Christ of Latter-day Saints to erect a new "technological barrier" in the system used for controversial posthumous or proxy baptisms.
Mormons around the world are getting this warning Sunday: Stop posthumous baptisms of "unauthorized groups, such as celebrities and Jewish Holocaust victims."
"Our preeminent obligation is to seek out and identify our own ancestors," says a letter to be read in every Mormon congregation. "Those whose names are submitted for proxy [baptisms] should be related to the submitter."
Many religious traditions stress the importance of charity. But Mormons are remarkable for the amount and the precision with which they give to their church.
The Church of Jesus Christ of Latter-day Saints teaches that each Mormon in good standing should tithe 10 percent of his or her income. The money goes right to church headquarters in Salt Lake City and then is distributed back to congregations around the world.
"That's written in stone, and preached from the pulpit," says Gordon Dahl, an economist at the University of California, San Diego, who is Mormon.
When GOP presidential candidate Rick Santorum was growing up, he says, John F. Kennedy was a hero in his Catholic home.
In a speech last year, he said he had always heard glowing reports of Kennedy's speech about religion to Protestant ministers in 1960.
"And then very late in my political career, I had the opportunity to read the speech and I almost threw up," Santorum told a group of college students last year. "You should read the speech. In my opinion, it was the beginning of the secular movement of politicians to separate their faith from the public square."
