The very first sentence of this article is spot on (as is the rest of it): "Scripture tells us that they will know that we are Christians by our love (John 13:35), but the media tell us that they will know that we are Catholics by our fights." Warring factions in churches are not limited to Catholics, either, but they blight the whole Christian message. Conflict and disrespect, seen even in these forums, is duly noted by many people. There will always be differing views on some things, but the unkind reactions to those who disagree,  extending even to vicious remarks toward them, has consequences.  I've heard young people say that disrespect they observe among church members is a reason that they are spiritual but not religious. Maybe the first step in evangelism is a culture change where we treat others in the church with exceptional kindness and gentleness, especially where we disagree. Wouldn't that be a powerful message to the world?
