Answer:
1. The political unity of the Roman Empire did produce a certain economic and political stability, notwithstanding its many faults. This encouraged trade between large cities and regions
2. The military and trade routes meant relatively easy access to large numbers of people (both by land and sea). Joel Kotkin writes, ‘Rome allowed considerable self-government to individual cities; the empire itself, notes the historian Robert Lopez, functioned as a ‘confederation of urban cells.’ Europe would not again see such a proliferation of secure, and well-peopled cities until well into the nineteenth century. People, products, and ideas traveled quickly through the vast archipelago of ‘urban cells’ over secure sea-lanes and fifty-one thousand miles of paved roads stretching from Jerusalem to Boulogne…Christianity’s rapid growth could not have taken plave without the empire’s expansive urban infrastructure.’ [i]
3. The universal use of Greek as a result of former conquests aided communication
4. The cosmopolitan atmosphere of the Empire – mixed cultures – enabled easier cross-cultural evangelism e.g., Jews who were culturally Greek (Barnabus from Cyprus, Paul the Roman citizen) were able to bridge cultures
