The early Christians were persecuted by the Romans. Christianity worships a single God who sent his Son to save the world. The Romans worshipped many gods, such as Jupiter, Minerva, Juno, etc. they had a god for emotions, food, battle strategy, marriage, victory, the list goes on. The Christians refused to worship these gods in the temples or take part in sacrifices or celebrations for the gods.
