"I think Christians should argue more, because it's healthy. They don't do it as well as the Jews do. If we look at the New Testament, Jesus is frequently arguing with fellow Jews, and what that means is it puts him right in the heart of Judaism rather than takes him out of Judaism. If you look at rabbinic literature, post-Biblical Jewish literature, it's "Rabbi This says this, rabbi That says that, some third rabbi says some third thing, the people do what they want, and they've been arguing over this stuff for two thousand years. The reason we can do it so well is because at the end of the day, we're all still Jews.
Jews never settle down just to be a religion and just to be a belief system. Jews have always kept an ethnic component or a people-hood component to who we are. So our arguments take place in the family, and just as a relatively healthy family will have certain disagreements, at the end of the day, you're all still brothers and sisters and parents and children.
What happens in Christian communities is if you argue too much, if you disagree too much, you put yourself out of the community, because if you get into a tradition by belief you get out by belief. I think if Christians took baptism more seriously, they'd be able to argue better. Because baptism means you're in the system, and it's not something that washes off."
