Why did Christians and Jew fight in the ancient times?
It was the Romans would fought with the Christians until the Emperor Constantine embraced Christianity as the religion of the Roman Empire, circa 313 AD! Albeit the fight was one-sided, Christians being fed to the lions, by Romans…Christian was simply a Roman “label” placed on this new group, which meant “Not-Jewish” (X-Jew, hence the Cross)… To the Jews, Christians were considered to be religious fanatics (as many still are today). All of the early Christians started out as Jews, and lived in Jewish communities, such as Antioch & Damascus, in modern-day Turkey & Syria… Jews mostly tolerated this zealous new sect within their religion, with the exception of the famous “Passion Play”, which was well documented, however this animosity was directed only at one individual, Jesus. It was not a “fight” per se!
