Christian unity "will not be the fruit of subtle theoretical discussions", Francis said at St Paul Outside the Walls in Rome yesterday evening (full text, full video). The Pope expressed "deep concern" at renewed fighting in Ukraine in his Angelus address (full text, full video). Fr Richard McBrien, the American theologian who once "had a higher media profile than anyone in the Catholic Church other than Pope John Paul II", has died aged 78. Francis is "truly sorry" that his comments about big families "created such disorientation", Vatican official Archbishop Giovanni Becciu has said. The Cause of Léonie Martin, sister of St Thérèse of Lisieux, officially opened at the weekend. John Allen asks if Francis is in a hurry because he believes we are in the end times.
