Godly people strive to understand each other; good people can differ out of pure motives.
Throughout the Middle Ages, Jews and Christians were consumed by hateful polemics about each other. They fought theological duels that sometimes led to deadly Christian violence against our ancestors. Christians no longer pose any existential threat to Jews, yet the penchant for hateful language has continued, particularly in my Orthodox community. Much of this venom is directed against ourselves in fraternal battles that are turning as lethal as the medieval Jewish-Christian warfare. Today the traditional fear and vilification of gentiles has been transferred to other Orthodox Jews with whom we disagree.
