Q: If not, then why would a place claiming to be a "Holy City" of the Father God do it on earth?
A: Because they are neither a Holy City of the Father God on earth NOR guided by His Spirit.
Exult not like the peoples;
for you have played the whore, forsaking your God.
You have loved a prostitute’s wages
on all threshing floors.
Hosea 9:1 ESV
"A dedicated prayer room for Muslims has reportedly been opened inside the 500-year-old Vatican Apostolic Library in Rome after a plea for the separate, carpeted space was made by visiting Islamic scholars.
The Catholic Herald reports Fr. Giacomo Cardinali, Vice Prefect, said in an interview with the Italian newspaper La Repubblica thatMuslim academics had requested an area in which to pray, and the library had agreed. “Some Muslim scholars have asked us for a room with a carpet for praying and we have given it to them,” he said.
In the interview, Cardinali referred to the library’s modern collections: about 80,000 manuscripts, 50,000 archival items, nearly two million printed books, and hundreds of thousands of coins, medals, engravings, and prints.
The library, located within Vatican City, traces its origins to Pope Nicholas V in 1451 and has since served as one of the world’s leading repositories of Christian and human knowledge.
The opportunity given by the Vatican for Muslims to pray in their own designated area is at odds with Islam’s own strictures
for its holy city.
