Circumcision is grievous bodily harm, German judges rule

[Mosby]

58. OK, almost all.

Of all of the commandments in Judaism, the brit milah (literally, Covenant of Circumcision) is probably the one most universally observed. It is commonly referred to as a bris (covenant, using the Ashkenazic pronunciation). Even the most secular of Jews, who observe no other part of Judaism, almost always observe these laws. Of course, until quite recently, the majority of males in the United States were routinely circumcised, so this doesn't seem very surprising. But keep in mind that there is more to the ritual of the brit milah than merely the process of physically removing the foreskin, and many otherwise non-observant Jews observe the entire ritual.

The commandment to circumcise is given at Gen. 17:10-14 and Lev. 12:3. The covenant was originally made with Abraham. It is the first commandment specific to the Jews.

Circumcision is (in general) a common denominator among movements: Reform, Conservative, Reconstructionist, Orthodox — all circumcise their male children and require male converts to undergo some form of circumcision.

I should point out that when I refer to Jews I'm talking someone who is engaged somehow with the religion.
