At the beginning of chapter 6 in Pope Francis' encyclical Fratelli Tutti, he explores what healthy dialogue looks like (and does NOT look like). He explains that true friendship and unity can emerge by talking with people we disagree with but only if it's done right. He lays out practical ground rules and explains the obstacles and pitfalls many of us get into when we are trying to work out difficult issues with others. Sifting through issues together can be a powerful method to discover fundamental truths about life we can all agree on.
