It all began with love in Galilee. Jesus had no army, no territory, no palace, no bureaucrats to govern an empire, and no wealth to pass on to future generations. What he left behind were a few words and his life: Love God, love your neighbor, even love your enemies. Do not overlook the least among you. If you want to be great, humble yourself; if you want to be served, serve others first.
And then Jesus died on the cross. By worldly standards, everything should have ended there. The leader was executed, and the disciples scattered. But it did not end. Those who believed in Jesus' resurrection gathered again, and that small community became the Church. The Church spread beyond cities and borders, proliferating throughout the Roman Empire despite persecution, eventually becoming a religion recognized by the emperor and later a cornerstone of European civilization.
Love became faith, faith became community, community became the Church, and the Church became an institution and a civilization. At that moment, the most challenging question in Christian history began: What happens when a religion that started with love gains power?
Peter and Paul: The Church Begins Its Journey
After Jesus' departure, Peter became the central figure of the early Jerusalem community. He was not perfect; despite his promises to follow Jesus to the end, he denied knowing him three times at a critical moment. He was afraid, stumbled, and failed. Yet he rose again.This is a significant symbol in Christian history. The Church did not begin as a gathering of perfect individuals but as a community of humans who stumble, regret, and start anew. Peter played a leading role in the early Jerusalem Church, and later Western churches understood the relationship between Peter and the Roman Church as a crucial root of the papacy.
However, to understand how early Christianity spread beyond the walls of Jerusalem, we must meet another figure: Paul. He was not a disciple during Jesus' lifetime and initially opposed those who followed Jesus, but after a dramatic conversion, he became one of the most important missionaries in Christian history.
Paul's decisive significance lay in expanding faith in Jesus beyond Jewish boundaries into the Gentile world. From Jerusalem to Antioch, then to Asia Minor, Greece, and finally Rome, the path was opened. In this process, the early community faced critical questions: Must one first become a Jew to follow Jesus? Must all of Moses' laws be observed? Can Gentiles become direct members of the Christian community?
Intense debates occurred within the early community. However, as the path for Gentile missions opened, the Jesus movement began to grow into an independent world religion, transcending its roots in Judaism. While Judaism brought books and questions to various parts of the world through the diaspora, early Christians spread the gospel using the cities, roads, transportation networks, and common language of the Roman Empire.
Missionaries walked the paths created by the empire for conquest and governance. It was a historical paradox.
The Persecuted Church Encounters the Empire
Early Christians were not the powerful ones. While the Roman Empire did not uniformly persecute Christians across all times and regions, the Christian community experienced oppression under various emperors and periods. The Christians' refusal to participate in emperor worship and polytheistic public rituals was sometimes seen as a challenge to the empire's religious and social order, leading to martyrs.During this time, the Church's strength lay not in power but in testimony. There emerged people who believed that while they could be killed, their faith could not be taken away. A powerful empire faced a powerless faith community. Yet history turned upside down.
In the early 4th century, under Emperor Constantine, a monumental shift in Christian history began. The Edict of Milan in 313 institutionalized religious tolerance, including Christianity, allowing Christians to escape long-standing persecution and practice their faith openly. They could establish churches and grow their communities institutionally.
For Christians, it was liberation. However, every liberation comes with new responsibilities. As the persecuted Church began to receive protection from the emperor, a completely new issue arose regarding the relationship between the Church and power. Is power protecting the Church, or is the Church justifying power? What are the limits of the emperor's authority, and what are the limits of the bishop's authority?
The community of love that began in Galilee began to approach the imperial court. Christianity was no longer just the religion of victims. It had gained power and was now questioned about how to use that power.
Nicaea: Faith Becomes Doctrine
In 325, Emperor Constantine gathered bishops from various regions in Nicaea for the First Council of Nicaea. The central issue was a fierce theological debate on how to understand Jesus Christ. Is the Son a creature? What is his relationship with the Father? The Church engaged in intense debates, and in this process, the foundation for the Nicene Creed was established, which would later develop into the doctrine of the Trinity. It was the moment when faith became doctrine.To explain what the community believes, language and standards are necessary. However, the moment standards are established, new questions arise: Who decides orthodoxy? Who defines heresy? To what extent can the Church's authority be exercised to preserve the truth?
The community that began with love created institutions to preserve the truth, and with that, the possibility of those institutions becoming power also emerged. The old tension that runs through 2000 years of Christianity began to take shape here.
Augustine: Focusing on the Inner Human
To understand Christianity at the end of the Roman Empire, one must pass through Augustine. The bishop of Hippo in North Africa experienced desire and wandering in his youth and returned to Christian faith after a long intellectual and spiritual journey.His focus turned to the inner human. Why do humans, knowing good, still do evil? Why do free-willed humans become slaves to desire? What is divine grace, and where is history headed?
In a time when Rome was shaking, he distinguished between earthly states and the Kingdom of God in his work, "The City of God." The earthly empire is not eternal. Rome can fall. Humans often mistake the power before them as eternal, but no state can become divine, which was one of his profound insights.
That question remains alive today. Loving the state is different from deifying it. Participating in society is different from religion itself becoming power.
Monasticism: Returning to the Wilderness from Power
As the Church grew and gained social influence and wealth, paradoxically, some began to leave the world and enter the wilderness. These were the monks. The early monks sought out deserts and remote places. They were motivated by the fear that the Church, gaining protection from the empire and social status, might lose the spirit of early Christianity characterized by poverty, restraint, prayer, and self-sacrifice.They reduced their possessions, prayed, and worked. The essential spirit of later Western monasticism was encapsulated in the phrase, "Pray and work." Monasteries did not remain mere religious facilities. They became spaces for education, manuscript preservation, scholarship, agriculture, charity, and healthcare in medieval Europe, preserving the flame of learning during times of societal chaos.
Within the Church that gained power, there emerged those who chose poverty again. Religion does not survive solely through institutions. There is always a need for those who return to the original spirit.
Roman Catholicism and Eastern Orthodoxy: Two Civilizations from One Root
As the Roman Empire divided into East and West, and distinct political, linguistic, and cultural environments solidified, the Eastern and Western Churches began to take on different forms. In the West, after the fall of the Western Roman Empire, the authority of the Roman bishop grew during the process of political disorder, and the Roman Church took on significant roles in social stability, diplomacy, administration, and charity.The papacy developed, and Latin became the language of the Western Church. The combination of theology, canon law, monasticism, cathedrals, universities, and art formed a vast tradition that would later be known as Roman Catholicism. The term "Catholic" itself originally means "universal."
However, the West was not the entirety of Christianity. In the Eastern Roman Empire, or Byzantine world, another great Christian civilization was growing. Ancient churches in Constantinople, Alexandria, Antioch, and Jerusalem developed theology, liturgy, iconography, and the thoughts of the Church Fathers within the tradition of Greek language and philosophy.
While the authority of the Roman bishop was strengthened in the West, in the East, a tradition emphasizing the collegiality and autonomy of various patriarchates developed. Language differences, political interests, and varying understandings of ecclesiastical authority emerged. The theological differences, including the so-called "Filioque" controversy regarding the procession of the Holy Spirit, deepened the conflict. The two traditions, stemming from the same root, gradually drifted apart.
1054: The East and West Divide
1054 symbolizes the great schism between the Eastern and Western Churches. The long-standing conflict between Rome and Constantinople erupted in mutual excommunication. However, it should not be understood that the Church, which had been together for nearly a thousand years, split precisely in half one morning in that year. The differences between East and West accumulated over centuries, and even after 1054, relations continued. Later, the Crusades and political conflicts further deepened the division.Nevertheless, 1054 is a historically significant turning point. The West followed the path of the Roman Catholic Church, while the major churches of the East followed the path of what is now known as the Eastern Orthodox Church. They believed in the same Jesus, read the same Gospels, and shared important traditions from the early councils. Yet they split.
Here, the old paradox of religious history emerges. The passion to preserve the truth sometimes transforms into a force that excludes others. Loving the truth is different from believing that only one's understanding of the truth is valid.
