Civil Duties Imposed by Rome
The Roman Empire required all non-Jews to participate in the civil religion.
The Romans tolerated all kinds of religious practices but no matter what your religion was or where you came from, they expected you to take part in the ceremonies and public events of Roman society.
It did not matter what religion you were, it was part of your duty as a citizen to be involved.
Serious consequences awaited those who did not participate, even without the death penalty.
For example, people could be ostracised from the trade guilds, in which they networked to build their businesses.
They would lose their influence on the development of society or the improvement of their position within it.
As a result, those who avoided Roman civil religion became poor, powerless social outcasts.
