No Christian Church Should Allow Non-Christian Worship under its Roof

I was gravely disappointed to learn that on November 14th, the National Cathedral allowed a Muslim only worship service to take place. This is blasphemy to Jesus and the cross. Since when do Muslim mosques allow us in to pray to Jesus? The Episcopal church should not become the namby pamby, stands for nothing version of Christianity, but it is in danger of becoming so. This Muslim service should not have happened.
