How are romans and jews alike?

Answer 1

They weren't.

One of the reasons that the Greeks and Romans hated the Jews was the stark difference of the Jewish practices (and not just the beliefs), as compared to those of the Greeks and Romans. The Jews, by and large, adhered to the practices of the Torah, which calls for kindness, charity, scholarliness, the value of human life, and the abhorrence of promiscuity.
Just a very few examples:
1) Aristotle, who was among the greatest of the Greeks, and Seneca, the famous Roman, both write that killing one's unwanted young babies is perfectly acceptable.
2) In Europe, the Druids practiced human sacrifice throughout Roman Gaul and the British isles. Virgins were sacrificed by casting them into wells.
3) In the Roman cities, the Bacchanalian feasts became so wild that a royal decree was promulgated that they be held outside city limits.
4) Prostitution was a fixed part of temple worship.
5) Children had no rights. In Carthage, babies were sacrificed in fire. Roman law (Patrias Potestas) permitted a man to kill his male descendants of any age and for any reason. Professor and former President of the American Historical Association, William L. Langer (in The History of Childhood), writes: "Children, being physically unable to resist aggression, were the victims of forces over which they had no control, and they were abused in almost unimaginable ways."
6) Under Israelite law, "an eye for an eye" has always meant the monetary value placed upon it by the court (Talmud, Bava Kama 83b). Roman law, however, included literal retaliation (Twelve Tables of Roman Law, 7:9).
7) Romans were killed for the crime of slander (Twelve Tables, 7:8).
8) A Roman could be killed for assembling a noisy crowd at night and disturbing the town (Twelve Tables, 9:6).

Given the vast difference between the two peoples, the Romans found it hard to stomach the kindliness and temperance of the Jews, and they lashed out with physical cruelty as well as slander. Tacitus, one of their greatest historians, penned the canard that the Jews originated as Egyptians who were expelled from Egypt due to disease (History of Jews V, ch.2). Today we can expose this claim for what it is, since DNA analysis shows that Jews were not Egyptians.
Not satisfied with that, he wrote that "the Jews are the most lewd nation on Earth," despite his own contradictory admission that "the Jews will not corrupt foreign women." He also claims that the Jews "are taught to have their parents, children and brethren in the utmost contempt" (ibid.), despite the Jewish Torah being one of the major sources of Western morality.

Answer 2

The Romans worshipped many gods and the Jews were (and still are) monotheistic. Another difference it that the Romans are extinct today, and the Jews are thriving.

Answer 3

There was very little similarity. The two had totally different cultures and religions.
