The Vatican Bank may be the size of a mid-tier investment bank, but it wields tremendous power and influence, said Gerald Posner, author of 'God's Bankers'. Posner added that it took him a decade to extensively research the book because the Vatican denied his requests at every turn. He said money was a motivating factor in the Catholic Church's silence in the face of the Nazis attempt to slaughter Jews throughout Europe. Posner said the Pope is the sole shareholder of the Vatican Bank and Pope Francis is indeed trying to change the bank by increasing its transparency the world over.
