Though far away from the center of the action in Rome, Bishop Celestino Aos, the temporary head of the embattled Archdiocese of Santiago, Chile, has a tough job. He’s replacing a cardinal being investigated for cover-up of clerical sexual abuse, whose predecessor is also being questioned by local prosecutors.During the Easter season, Bishop Aos might have made his own job even harder when on Holy Thursday during the Chrism Mass he was filmed denying communion to at least two faithful who were kneeling down.
