Liberation Theologist Leonardo Boff, of Brazil, speaks at a book fair where he attended the launching of a book by Clelia Luro, the wife of former bishop Jeronimo Podesta, in Buenos Aires, Argentina, Saturday, April 27, 2013. Liberation theologist Leanardo Boff says Pope Francis has what it takes to fix a church “in ruins.” Previous popes tried to silence the Brazilian leftist, but Boff says the former Argentine cardinal who became pope last month has both the vigor and tenderness to create a new spiritual world.
