FILE - In this June 2, 2012, file photo, Pope Benedict XVI is greeted by nuns during a meeting with priests and religious at the Duomo gothic cathedral, in Milan, Italy. Benedict has been trying to restore Catholic traditions he believes were lost 50 years ago in the modernizing reforms of the Second Vatican Council. As he presses for a more conservative Catholicism, the pope has been vigilant about ensuring that groups and individuals that operate in the name of the church are adhering to core Catholic teaching. The Vatican orthodoxy watchdog, the Congregation for the Doctrine of the Faith, concluded in April that the Leadership Conference of Women Religious had strayed far from authentic doctrine and gave three American bishops the authority to overhaul the organization. The board for the nuns’ group responded by calling the Vatican’s investigation flawed and its conclusions unsubstantiated. Top executives of the sisters’ organization are bringing their concerns to a meeting Tuesday, June 12, in Rome with Vatican officials. (AP Photo/Luca Bruno, File)
