There are places in the world where there are very few Jews, and where Judaism is officially or unofficially forbidden by the state. One of the great mysteries of the Internet, to me, is that periodically someone in one of those countries will write to my friends at BecomingJewish.net and inquire about conversion to Judaism.
All the folks at BecomingJewish.net can do is write back to them and explain that (1) it isn’t safe to convert to Judaism in their country and (2) there are few or no Jews there, so it isn’t possible to convert.
On the one hand, it makes me sad to think that someone who wants to be Jewish is living in a place where they simply cannot become Jewish. On the other hand, it speaks to a real misunderstanding of Jewish life, because even if they could convert, they could not have any kind of meaningful experience of Jewish life without a community.
Judaism isn’t something you do by yourself. It isn’t private, it isn’t personal. It is communal. We pray in a minyan, a group of ten or more. We have a minyan for important occasions, like a bris. How can you have a seder, if you have no one with whom to discuss? We don’t even study alone!
This is why my first advice to anyone converting to Judaism is to find a rabbi, find a community, and to be regular at everything: services, events, and so on. It’s only by spending time with Jews that you can learn to be a Jew, and get the goodies of Jewish life.
As for the people writing letters from Pakistan and Saudi Arabia to BecomingJewish.net, I have no idea what’s going on there. If they are real, I hope they can find their way to a place where there are more Jews.
