Why did Romans blame and punish the Christians for all kinds of disasters?

Answer 1

There is no real evidence that the Romans ever punished the early Christians for any kind of disaster. The preferred official reaction to the presence of Christians was that if the Christians were discreet about their refusal to worship the Roman gods, they could be ignored.

A Christian tradition holds that, in the mid-first century, Nero persecuted the Christians living in Rome because he blamed them for the Great Fire, but historians have been unable to find any evidence of such persecution or even a reason for Nero to want to blame them unjustly.

The Romans believed that by refusing to worship the gods, Christians were risking divine wrath. So, while there is no real evidence that this occurred, there may have been isolated instances of Christians being punished because their lack of faith in the Roman gods, (for which they were accused of being atheists) which supposedly brought disasters on the people.

Answer 2

Romans blamed and punished Christians for various disasters due to their religious beliefs being seen as a threat to the empire's stability and unity. Christians refused to participate in the traditional Roman religious practices, which was viewed as a betrayal of the gods and potentially angering them. This led to Christians being scapegoated for any misfortunes or calamities that occurred during the Roman Empire.
