"Is Rome using Marian Sanctuaries to win over Islam" -- you better believe it.
Rome is uniting all religions under her banner. The popes kissing the koran, praying in mosques, etc. The tie that brings them together is the catholic churches version of Mary.
The Koran denies Jesus as the Son of God yet it refers to Him as the son of Mary many times. Muslims refer to her as "our lady" as well as catholics.
They need to read Jeremiah chs. 7 and 44, and Isaiah 47 to see what the Bible says about the "queen of heaven" and "lady of kigdoms" (long before Jesus' mother was ever born by the way)
I would recommend to everyone to read the book "Babylon Religion" by David Daniels. It shows how satan's counterfeit religion started at the tower of Babel and is still alive and well today only it has Christian names to replace the pagan names. Good ole Roman(satanic)religion.
The sad part is that Rome is being very successful in bringing fundamental Protestant and Baptist churches back/into its fold. The ecumenical spirit is moving fast. I pray that God will destroy this false religion of the devil quickly.
