Religion was very important to the Romans. Within the Roman Empire, Christianity was banned and Christians were punished for many years. Feeding Christians to the lions was seen as entertainment in Ancient Rome.

The message of Christianity was spread around the Roman Empire by St. Paul who founded Christian churches in Asia Minor and Greece. Eventually, he took his teachings to Rome itself.
The early converts to Christianity in Ancient Rome faced many difficulties. The first converts were usually the poor and slaves as they had a great deal to gain from the Christians being successful. If they were caught, they faced death for failing to worship the emperor. It was not uncommon for emperors to turn the people against the Christians when Rome was faced with difficulties. In AD 64, part of Rome was burned down. The Emperor Nero blamed the Christians and the people turned on them. Arrests and executions followed.
punished a race of men who were hated for their evil practices. These
men were called Christians. He got a number of people to confess. On
their evidence a number of Christians were convicted and put to death
with dreadful cruelty. Some were covered with the skins of wild beasts
and left to be eaten by dogs. Others were nailed to the cross. Many were
burned alive and set on fire to serve as torches at night."
The dangers faced by the Christians in Rome meant that they had to meet in secret. They usually used underground tombs as these were literally out of sight. Rome had a large number of poor people within its population and Christianity continued to grow. In AD 313, the Emperor Constantine made Christianity legal and for the first time, they were allowed to openly worship. Churches were quickly built not just in Rome but throughout the empire. In AD 391, the worship of other gods was made illegal.
