Catholic nuns in the U.S. have been thumbing their nose at Rome’s demands to toe the doctrinal line and they need to obey or face serious consequences, the Vatican’s enforcer of orthodoxy said in a surprisingly tough talk to women representing most American sisters.

“The Holy See believes that the charismatic vitality of religious life can only flourish within the ecclesial faith of the church,” Cardinal Gerhard Mueller, head of the Vatican’s Congregation for the Doctrine of the Faith, told four members of the Leadership Conference of Women Religious.

Mueller said the LCWR — which represents about 80 percent of the more than 50,000 Catholic nuns in the U.S. – is dependent on the Vatican for its bona fides as a church body. He indicated that the group’s status, and the Catholic faith of the sisters, was at risk if they did not heed Rome’s directives.
