who played the most influential role in the early spread of christianity
Role of Christianity in civilization The early followers of Jesus, including Saints Paul and Peter carried this new theology concerning Jesus throughout the Roman Empire and beyond, sowing the seeds for the development of the Catholic Church, of which Saint Peter is remembered as the first Pope. Catholicism, as we know it, emerged slowly. Christians often faced persecution during these early centuries, particularly for their refusal to join in worshiping the emperors. Nevertheless, carried through the synagogues, merchants and missionaries across the known world, the new internationalist religion quickly grew in size and influence.[13] It's unique appeal was partly the result of its values and ethics.[14]
Constantinople Constantine's foundation gave prestige to the Bishop of Constantinople, who eventually came to be known as the Ecumenical Patriarch, and made it a prime center of Christianity alongside Rome. This contributed to cultural and theological differences between Eastern and Western Christianity eventually leading to the Great Schism that divided Western Catholicism from Eastern Orthodoxy from 1054 onwards. Constantinople is also of great religious importance to Islam, as the conquest of Constantinople is one of the signs of the End time in Islam.
