Why Do We Have a Circumcision?

Why Do We Have a Circumcision?



A friend asked the other day why we have a bris (circumcision). I rambled on about health, tradition, old people, eight days, pain and a whole lot of other nonsense before leaving this one to you.


The bris is a physical symbol of the relationship between G‑d and the Jewish people. It is a constant reminder of what the Jewish mission entails (a reminder which men need more than women). Let’s look at its details:

If circumcision is what G‑d wants, why aren’t we born circumcised? G‑d created the world imperfect, and gave us the mission to perfect it. G‑d created wheat; humans make bread. G‑d created a jungle; humans create civilization. The raw materials are given to us, and we are to use our ingenuity to improve on the world that we were born into. This is symbolized by the bris—we are born uncircumcised, and it is up to us to “finish the job.” This is also true metaphorically. We each have instincts and natural tendencies that are inborn, but need to be refined. “I was born that way” does not excuse immoral behavior: we are to cut away any negative traits, no matter how innate they may seem.

Why on earth would G‑d choose circumcision to represent something sacred? Jewish spirituality is about making the physical world holy. The way we eat, sleep, work and procreate should be imbued with the same holiness as the way we pray; our homes should be as sanctified as our synagogues. We find G‑d on earth just as much (and perhaps more) than in the heavens. So we put a sign on the most physical and potentially lowly organ, to say that it can and should be used in a holy way. In fact, it is in sexuality that we can touch the deepest part of our soul—when we approach it with holiness.

Why circumcise a baby? Wouldn’t the statement be more powerful if it were made by a mature adult? The circumcision is performed when a child is still not aware of what is happening. This is because the Jewish connection to G‑d is intrinsic: whether our minds believe in G‑d or not, whether our hearts love G‑d or not, our souls know G‑d. We can join the covenant with G‑d even without being consciously aware of Him, because subconsciously we already know Him.

Why specifically on the eighth day? The number seven represents nature—seven days of the week, seven colors of the rainbow, seven musical notes (do re mi, etc.); the number eight is the number that surpasses seven, and thus represents the miraculous, what is beyond nature. We do the bris on the eighth day because the Jewish people survive on miracles. Our history defies the laws of nature. We welcome a new Jewish child into this miraculous existence on the eighth day of his life, as if to say, “Expect miracles!”

God did not create an imperfect world
I wholly disagree that God created an imperfect world, because God does not create imperfection. When man fell, i.e. sinned, the world was then tainted, i.e. became imperfect. Man has been striving for perfection ever since.
The eighth day is also scientifically significant. In the human body, the presence of prothrombin, vitamin k, which is essential for blood clotting, is at the highest it will ever be. God said eight days, then prepared the body accordingly!

Re: Sources
You'll find that in Midrash Rabba, Genesis 11:6. It's translated in our article "Tikun: Fixing Up the World"

Don't call it Judaism. Torah-true living is not an "-ism" and this term never occurs in
the TaNaKh or in the Talmud. It was invented, as an "ism," by the Christian church, along with the word "paganism"--in order to claim that ChristianITY was "better" than these "isms".

They do not "convert to Judaism". They are admitted to the Sinaitic covenant and, in the case of men, to the Abrahamitic covenant.

Could you please list the sources you used to answer "why aren't we born circumcised"?
Thank you so much! (Gemara project)

Interesting (to M. Posner)
Dear Menachem, Thanks for your answer. I am amazed. If anyone knows why is it so, I would be interested too.

To Sarah K.
The Talmud tells us that women are considered to be born circumcised. On other words, whatever *fixing* that circumcision does to a male child already exists naturally within the Jewish woman.

Very nice discussion ! Maybe in addition bris is more generally reaffirming readiness for sacrificing ourselves for G. ? Q:Why the man has more need of that than the women? Maybe because only men become rabbis? (or at least in old times)
With best regards,

Re: Conversion
I see that many are asking questions here about conversion. Most of these questions are dealt with in another article on our site: Why Is Conversion To Judaism So Hard?

Re: Hrm
"One does not become Jewish by believing, nor cease being Jewish by not believing".

I am not sure if I understand Rabbi Brownstein's explanation fully.
I can see that Judaism is not like other religions where the person can claim to be a member of a faith just by saying 'I believe' , since Judaism (in the Orthodox sense) entails much more than mentally saying that you believe.
But how does it work then in case of a female convert to Judaism , where there is no circumcision but is still accepted as a Jewess at the end of the conversion process? Is the fact that she not only believes but also immerses in the Mickvah and observes the Law allowes her to enter into the Covenant / Judaism? I am not a skeptic, but just genuinely curious as to how it works.

Rabbi Brownstein is right 100%
Just in case my prior post fails to make that clear, his explanation is standard Jewish thought. It's not about "religion" as in performing a ritual to make something happen. It's not about beliefs. It's about a covenant. Read the verses I cited from Genesis 17:9-14. Obeying a covenantal commandment from Genesis is about as vital and basic as it gets!!! It's more fundamental even than the covenant at Sinai.

But the rabbi said it better than I seem to be able to do.
