A priest, a monk and a rabbi are debating which of their religions is the correct one. They decide to settle it with a contest to convert a bear to their religion.
The rabbi tries first. Two days later, the priest and the monk end up visiting him in the hospital.
The rabbi says: “OK, maybe I shouldn’t have begun with circumcision.”
Let’s set aside the foreskin jokes, because I don’t think the rabbi would have had much better luck with a lady bear. Isn’t it a strange fact of our religion that we almost never set out to proselytise?
We, of course, welcome all sincere converts, and this synagogue is happy to encourage anyone on their spiritual journey. But you won’t find us outside Asda, handing out flyers with words from the Mishnah. And you certainly won’t turn on your TV to see a rabbinic televangelist warning you about the perils of pork.
But if you think you have stumbled upon spiritual knowledge, don’t you want to share it with the world? Who are we to zealously guard the secrets of the universe?
Even if you take a more humble approach to Judaism’s teachings, and think they’re just as good as any other people’s, there must be something particularly worthwhile about Judaism for you to log in to this morning’s service rather than watching Bargain Hunt. (Wait, don’t go, I promise this is going somewhere!)
That strange paradox of Judaism – that we have a universal truth but don’t seek to spread it – is encapsulated in the story of Abraham.
This week, God tells Abraham: “Go out by yourself. I will make your name great and you shall be a blessing.”[1]
Then, in the next two verses, as if a parallel to the first, God says: “All the families of the earth shall be blessed by you.” Then Abraham goes out with Lot and Sarah.[2]
So… does Abraham go out to bless himself or does he go out to bless others? Which is it?
This is the great tension in Judaism. Do we exist only for Jews? If so, why are we trying to change the world? Or do we exist for humanity? In which case, why aren’t we trying to make everyone Jews?
Our midrash plays with this tension. Bereishit Rabbah, a collection of rabbinic explorations of Genesis, contains an unusual parable. In it, Rabbi Berekhyah compares Abraham to a tightly sealed bottle of perfume. The bottle was left in the corner and nobody smelt it. As soon as it was moved, its fragrance was emitted. This, says our midrash, is what it was like when God told Abraham to go out from place to place and make his name great in the world.[3]
Makes perfect sense, right? No? Fine, let’s unpack it.
Abraham is a tightly closed bottle of perfume when he starts out in Haran. At this stage, Abraham has encountered God. Abraham has realised that the idols amount to nothing and the Creator of the Universe is a singular and invisible presence. He is somehow pure and untouched. The Pagans have not affected his beliefs, and he has not affected theirs. He is hermetically sealed.
Then God tells him to lech lecha – to go out. Abraham moves around out from Haran and down to Shchem and Be’ersheva in the land of Canaan. As he moves between these places, others get to smell him. They encounter the truth that Abraham has learned about ethical monotheism. God is one and just! Now everywhere he goes people can get a whiff of this knowledge.
Only there’s another problem. Bottles of perfume don’t emit their scent because you move them. They only work when you open them. In this analogy, the balsamic bottle that is Abraham still remains sealed. How is he spreading his fragrances everywhere if he hasn’t even opened up?
I don’t think the editors of our midrash have made some mistake. I think they are telling us something profound about the Jewish paradox. We have a truth that we want others to know and yet we don’t want to convert anyone. Our role as a light unto the nations is that we go from place to place, showing others who we are, but not changing anything about who they are. We are still Abraham, that sealed bottle, going out from Haran, somehow expecting others to smell our perfumes but not opening up wide to spread our scent.
The very word “evangelism” is a Greek one, meaning good news, referring to the Christian Gospels. The early Church actively went out on recruitment drives, telling people about Jesus and his message. We have no such good news to share. What would we say to people? “Rejoice! God has commanded you to pursue justice and only eat unleavened bread in the springtime!” Jewish evangelism seems somehow a contradiction in terms.
And yet we do go out and share our beliefs. We are happy to expound our Torah to anyone. We expect to transform the societies we are in. When we speak out for justice wherever we live, we are very much hoping that others will take note of our concern for the stranger and adjust their actions accordingly. How can we reconcile this desire to change others with our lack of desire to convert them?
Perhaps the problem isn’t perfume metaphors and paradoxes. Maybe the issue is how we understand Judaism’s mission. Abraham wasn’t sent out to turn others into Jews. Abraham was sent out to be a Jew.
Abraham had to go out and be different, to hold a truth that no one else held. Even when he passes it on to his children, they each hold a different truth. Isaac becomes the founder of our Judaism. Ishmael becomes the founder of Islam. They go out holding different truths, both contradictory and complementary. Abraham’s revelation of God’s unity is a realisation that this universal God can never be captured by one person in a single truth.
Abraham’s mission wasn’t to make everyone Jews. It was to enable everyone to be themselves. It was that all these other nations could celebrate their differences, just as Abraham loved his own.
That is our task today. We don’t say to the nations: “we want you all to be Jews.” We say: “we want you all to be you.”
We are models of difference in a society where we are not a majority and in a world where we are not dominant. Our role is to show how to conduct that uniqueness in a way that demonstrates dignity.
This is our evangelism. That is the truth we hold and that we want to share. That difference is a wonderful and treasured thing. From our differences, we are blessed. And in our differences, we bless each other.
So go out from Haran and share that sacred truth. And don’t worry – you don’t need to go circumcising bears.
