A leadership group of American nuns supports President Obama's healthcare reform, even though the US Conference of Bishops call it a threat to religious liberty. Now the nuns say they're "stunned" by blistering criticism and threats of de-certification by the Vatican for what it calls "doctrinal problems" and "radical feminist themes." When they went to Rome to confront Cardinal William Levada, the former Bishop of San Francisco, who's leading the the crackdown, he called it a "dialogue with the deaf." But the nuns aren't backing down. Are American Catholics caught in a battle between religious obedience and partisan politics?
