A nun walks under the Bernini colonnade in St. Peter's Square at the Vatican, Friday, Feb. 15, 2013. Pope Benedict XVI signed off on one of the last major appointments of his papacy Friday, approving a German lawyer and financier to head the Vatican's embattled bank. Ernst von Freyberg has solid financial and Catholic credentials as a former investment banker and member of the Sovereign Military Order of Malta, an ancient chivalrous order drawn from European nobility.
