"The Roman Catholic bishop of Cordoba in southern Spain has rejected an appeal from Muslims for the right to pray in the city's cathedral, a former mosque.
Juan Jose Asenjo rejected the request made by Spain's Islamic Board in a letter to the Pope.
It had asked that the cathedral become an ecumenical temple where believers from all faiths could worship.
The bishop said such a move would not contribute to the peaceful co-existence between people of different religions.
On the contrary, he said in a statement late on Wednesday, 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."
