Do Jews offer sacrifices today?
No. To my knowledge, no Jews today offer any kind of animal sacrifice or offerings, nor have Jews offered sacrifices since the second century C.E. I have occasionally heard rumors that there are Orthodox rabbis in Israel who practice the techniques of ritual sacrifice, so that the knowledge will not be lost, but I do not know if these stories are reliable, and even if they are, this is not quite the same thing as offering a sacrifice.
