Jews and Christians have never been together for because of the very basic fact that Jews hate Jesus. That can fact can not be reconciled in a way that puts them together. Christians can to their own determent, tolerate Jews in their midst, Jews will always at every opportunity, try to screw over Christians because it is their duty.
There is no way to reconcile two groups where one group's constitution says you must rule over the other group unless you change the constitution in a way that dictates that group lives in harmony with other groups and has no right to screw over other groups; then you have a different group because it's founding principles are no longer those of a parasite.
