An update indicates the caller was the Sostituto, Archbishop Edgar Pena Parra which underscores the mammoth clout and complete access of the Vatican’s de facto “chief of staff”. Of course he would have known the pope was in a public audience. Why would he call and expect the Holy Father to take the call which His Holiness did. How peculiar, how odd, and is this more “court-intrigue” and a hireling making a narcissistic point about how important he is?
Very odd. What could be so important? Something like Pope Emeritus taking back his renunciation?
