Answer:
by the sword of the bible
Step-by-step explanation:
In the first few centuries of Christianity, the Roman establishment felt threatened by this new religious movement and Christians were at times persecuted under Roman rule (This will be discussed in detail further on). However, the spread of Christianity was only possible because of the stability and unification of the Mediterranean achieved by the Romans. The Romans had successfully unified the entire Mediterranean into a relatively peaceful and prosperous trading system. Communications between the various peoples of the Mediterranean had become streamlined into two major languages: Latin in the Western Mediterranean, and Greek in the Eastern Mediterranean. This prosperity and unification assisted early missionaries such as St. Paul in getting the word out about the new faith. (Map 1 shows the cities across the Mediterranean that St. Paul visited). The early centers of Christianity were the largest cities and the most urbanized provinces on the major trade networks of the Mediterranean.
