Emporer Constantine
A:Generally speaking, no. Certainly, Nero expelled the Christians from Rome, but this was on the accusation that they started the Great Fire, not because of their worship. They soon returned and by the third century, there were several grand churches in Rome: certain evidence against the need to worship in secret. Nevertheless there were short periods, especially under Emperor Decius and again in the early fourth century, when Christianity was proscribed and Christians probably had to worship in secret.
The early Christians refused to worship the official gods of Rome.
Yes they did in secret rooms in their house
Because the Christians would not partake of Emperor worship and because they were somewhat secretive in their worship, believers received the wrathful displeasure of some of the Roman Emperors.
Primarily, Christians worship in churches on Sundays.
A martyr is someone who suffers or dies because of their beliefs. The Christians in Rome were persecuted/killed because they would not worship Roman gods or take part in sacrifices.
Christians do not worship using a mat.
Emperor Nero of the Julian-Claudian Reign started a fire in Rome and blamed it on the Christians. He used them as scapegoats in order to persecute them because The Patricians, or wealthy class, were atracted to Christianity and if they became Christian they would not "worship" or respect the Emperor because Christians only worship the one true God, and Patricians were the Emperor's power source.
Christians worship God. We often worship with our hands up in the air in worship towards God.
Christians worship everywhere. "other" Christians worship in Isreal, or Nazareth, or Bethlehem.... but Christians still worship everywhere
The Christians of Rome were, probably unfairly, blamed for starting the Great Fire of Rome. Some thought that any catastrophe that befell may have been brought about by the anger of the gods, because the Christians did not worship them.
