VATICAN CITY - The Vatican appointed German lawyer Ernst von Freyberg to be the new president of its bank on Friday, filling a post left vacant since May when the previous head was ousted by its board.The Vatican has been trying to shed a reputation for a lack of financial transparency at its bank, officially known as the Institute for Works of Religion (IOR), but has been dogged by scandals.A Vatican statement said Freyberg brought "a vast experience of financial matters and the financial regulatory process."
