Unfortunately the Pope and it's membership are "inviting" them in... the pope wants the two religions (Christianity and Islam) to be friends....a 'serious' mistake...as does our government....so their can be no agreement...it IS a battle for the souls of men
That is your one world religion. Did you know that the Koran speaks highly of Jesus and even says Mary was sinless.
They believe the coming man of sin will be Jesus the Messiah returning to pick up where he left off and they will fall down and worship him along with the rest of humanity.
