Francis "shocked" residents of a shantytown when he paid them a surprise visit yesterday on his way to celebrate Mass in a Roman parish (full video). The Pope described the sick as "the flesh of Christ" at the Angelus (full text, full video). Metropolitan Hilarion appeals for a "strategic alliance" between Catholic and Orthodox believers. Cardinal Gerhard Ludwig Müller argues that Francis "is pursuing a spiritual cleansing of the temple" at the Vatican. Fr John Zuhlsdorf suggests this could be a "pivotal week" in Rome. Sister Mary Ann Walsh says "mercy has jumped in from every corner to help me" since her diagnosis with cancer. And a new website shows how Catholics around the world live out the faith.
