Do orthodox christians eat pork and are they circumcised?

Peace be with you. I want to know if Orthodox Christians eat pork, and are they circumcised? I am referring to the early church which is the Orthodox Christians because in the Bible it says Yeshua (messiah) never ate pork and he was circumcised. Pork is haram as I understand. Do the Orthodox Christians follow this even today: circumcision and not eating pork?
