Unity is mission critical because unity authenticates our message. It makes us credible and convincing. Disunity makes us, well, it makes us like everybody else. Public shaming, theological elitism, heresy hunting, name-calling—those confirm the suspicions of those looking for reasons to size us up and write us off as posers, users, and hypocrites. That behavior undermines our influence, silences our voices, and causes outsiders to wonder why we insist on referring to our message as good news.
