I might trade them for letting the Pope pray in the Hagia Sophia, but that ain’t gonna happen. Nor have they done anything about this.
It wasn’t just praying, by the way. The Beeb says they “had asked that the cathedral become an ecumenical temple where believers from all faiths could worship.”
Said the Bishop:
…the joint use of temples and places of worship would only generate confusion amongst the faithful. Shared use of places of worship could make sense in airports or an Olympic village, said the bishop, but not in a consecrated Catholic cathedral.
