ATHENS, Greece (AP) — Church bells have rung “in mourning” across a western Greek diocese to protest the passing of a law making it easier for people to officially change their gender.

Under the guidance of Metropolitan Amvrosios of Kalavryta, a fiery conservative Orthodox bishop, clerics in his diocese decided that starting Sunday church bells are to ring every day, through Saturday, at noon for three minutes. They also called for the repeal of the law.

The law, passed with 171 votes in favor in the 300-member parliament last week, allows Greeks over the age of 15 to change the gender listed on their identity cards and other official documents following a simplified procedure in court. Until now, they had to prove they had undergone sex-change surgery and psychiatric assessment.
