"It was a mosque long before it was a cathedral,in fact the cathedral is built inside the mosque. "
from the English section of the webpage linked below:
"In 780 AD, begin the construction of the biggest mosque the world had ever known over
the structure of what it was known as the visgothic church of Saint Vincent."
http://www.cyberspain.com/ciudades-patrimonio/fotos/cormez.htm The Islamics have a very selective memory about how their mosque got in Cordoba.
Or how 30,000 Christian churches/shrines in the Holy Land were either destroyed or
appropriated during the Muslim Crusade (Jihad) of the mid 7th Century.
I'm not Catholic, but I'd heartily applaud the Pope if he said that "limited time
engagements" might be arranged...once the "peaceful" Muslims started handing
over Osama bin Laden, etc. to responsible legal authorities (like John Ashcroft).
