Rabbi Eric Yoffie, president of the liberal Union for Reform Judaism, said "religious right" leaders believe "unless you attend my church, accept my God and study my sacred text you cannot be a moral person."
"What could be more bigoted than to claim that you have a monopoly on God?"
conservatives too narrowly define family values, making a "frozen embryo in a fertility clinic" more important than a child, and ignoring poverty and other social ills.
"When they cloak themselves in religion and forget mercy, it strikes us as blasphemy," Yoffie said, urging a renewal of religious tolerance in the United States. "We need beware the zealots who want to make their religion the religion of everyone else."
Yoffie also urged lawmakers to model themselves on presidential candidate John F. Kennedy, who famously told a Houston clergy group on the campaign trail in 1960 that a president should not make policy based on his religion.
