CORDOBA, SPAIN – Mansur Escudero knew the answer before he asked. Approaching the guard at Cordoba’s majestic once-a-mosque, now-a-cathedral, Escudero posed the question: May I say Muslim prayers inside? The slightly startled Spanish guard gave an emphatic no. This is a Catholic church, he said, and as such it is absolutely prohibited to pray in any other faith. Escudero persisted, but the guard was firm. This is a cathedral, the guard repeated, growing more agitated: “A CA-THO-LIC CHURCH.”
