I think rapture and Jews aren't necessarily going to be considered in the same breath.
We circumcise (we were at our elder nephew's -- the men cringed and the woman all made sure the baby was fine. He's fine; he's 12 1/2 now) but not for any sense of the coming of the Messiah. We do it in order to demonstrate our covenant with God. It's probably also intended to show a difference between Judaism and other religions from the time, much like kosher laws are. It's a setting apart kind of thing.
