In 2011, Pope Francis co-
authored a book with Rabbi Abraham Skorka: Sobre el Ciele y la Tierra (On Heaven and Earth).
Concerning interreligious discussions, then-Cardinal Bergoglio of Argentina wrote: "Dialogue is born from an attitude of respect for the other person, from a conviction that the other person has something good to say. It assumes that there is room in the heart for the person's point of view, opinion, and proposal. To dialogue entails a cordial reception, not a prior condemnation. In order to dialogue it is necessary to know how to lower the defenses, open the doors of the house, and offer human warmth."
