I have many Catholic family members and they don't believe the Bible either. At best they have been taught to believe it is stories / allegories but not to be taken literally. They believe that they should obey the Pope. Not God. In essence, they believe the Pope has the authority of God and that the same type of authority / power belongs to their priests as well. They believe their priests have the power to forgive their sins and that their salvation can only come through the Roman Catholic Church. None of this is scriptural but when they are shown that in the bible their response is they don't believe the bible or take it literally.
If they believed the bible they would know that Jesus never taught his church to build an army, to have a court system or a Vatican, to hoard billions in gold,silver, precious gems and art work in a Vatican vault, Jesus never told the church to establish a bank (Vatican banks) nor create the United Nations to seize lands, whole islands, castles, palaces, archaelogical sites, private properties for their own private pleasure and use (UNESCO World Heritage:
UNESCO World Heritage Sites: UN Controls Priceless Lands and Monuments | Alternative), Jesus never appointed a Vicar, that Jesus never taught a church to start a war or seek world dominating political power over Kings, Queens and Presidents. Jesus never taught any church to raise up death squads and spy agencies who murder in the name of God - such as the Jesuits are. Roman Catholicism is actually based on a Babylonian religion that has nothing to do with the Bible. We talk about the Palestinians being an Arab invention but who was behind the scenes orchestrating this from beginning to end? The Vatican. Of course. They are the force behind the UN, the IMF, the World Bank, the wealth of the Vatican is greater than any other single organization on earth. It's utterly corrupt, evil and the religious component that has been set in place for the future One World Order Government. The Vatican's goal has always been the same, to take Jerusalem for its headquarters. They having been using the Muslims to accomplish this goal - for centuries - read Dr. Alberto Rivera - ex - Jesuit and he will explain why the Vatican is using the Muslims. What will happen in the end?
I suspect that after the Vatican uses the Muslims to wipe out the Jews and Christians who resist Rome's authority they will turn on the Muslims for one final crusade and kill them all. The Vatican has always worked both sides of every war, every coup, every agenda. It's their way of being in control of both sides.
