Answer:
By Paul and Jesus' Disciples
Step-by-step explanation:
The spread of Christianity was made a lot easier by the efficiency of the Roman Empire, but its principles were sometimes misunderstood and membership of the sect could be dangerous.
Although Jesus had died, his message had not. Word of his teachings spread to Jewish communities across the empire. This was helped by energetic apostles, such as Paul and by the modern communications of the Roman Empire.
