5 Things You Probably Didn’t Know About the Early Christian Church

Most of us have a simplified picture of the early Christian Church — a straightforward story of faith spreading from a small group of apostles to the wider world. But the real history is far more complex, political, and fascinating. Here are five of the most counter-intuitive truths about the early Church.

1. They Weren’t “Byzantine”—They Were Romans

The “Byzantine Empire” never actually existed, at least not to the people who lived in it. The term is a much later invention, coined by German historian Hieronymus Wolf in 1562. The inhabitants of this empire, centered in Constantinople, continued to identify themselves as Romans for centuries. Using the term “Byzantine” creates a false sense of separation from the classical Roman Empire that the people of the time would not have recognized.

2. The Church Was Governed by Five Senses

In the early centuries, the Church was administered through a system known as the “Pentarchy” (from the Greek for “rule of five”), officially established by the Council of Chalcedon in 451 AD. Governance was shared among the bishops of five major centers: Rome, Constantinople, Alexandria, Antioch, and Jerusalem. As Peter, the Patriarch of Antioch, described it: “For as our body is regulated by five senses, so the Body of Christ, the Church of the faithful, is regulated by the five thrones as if by five senses.”

3. The Pope Was Originally “First Among Equals,” Not an Absolute Ruler

In the early Church, the Bishop of Rome was honored with the title Primus inter pares — “first among equals.” This position acknowledged Rome’s historical significance, but it did not grant the Pope supreme authority over the other Patriarchs. Major decisions were made in Ecumenical Councils where all Patriarchs collaborated. This dynamic shifted dramatically in the 8th century under the influence of Frankish rulers like Pepin and Charlemagne, who freed the Pope from political dependence on Constantinople.

4. Political Power, Not Just Faith, Shaped the Church Hierarchy

While we often think of the Church hierarchy as based on spiritual or apostolic lineage, political reality played a decisive role. After Emperor Constantine made Constantinople his capital in 324 AD, its ecclesiastical status was deliberately elevated to match its political power. Canon XXVIII of the Council of Chalcedon made the reasoning explicit: the city which is the seat of an empire “should be magnified… in respect of ecclesiastical affairs.” This elevated Constantinople above much older apostolic sees like Alexandria (founded by St. Mark) and Antioch (founded by St. Peter).

5. One of the Earliest Churches Championed Radical Inclusivity

The Church of Antioch, founded by the Apostles Peter and Paul, distinguished itself by welcoming Gentiles (non-Jews) without requiring them to adopt Jewish customs or undergo Jewish initiation rituals. This was a significant deviation from the prevailing norms and profoundly impacted the expansion of Christianity. Its leadership was also remarkably diverse — the book of Acts (13:1) lists its prophets and teachers, including Manaen, who had been brought up with Herod Antipas, the very ruler who had executed John the Baptist.

Conclusion: History Is a Conversation

The history of the early Church is not a simple, linear story. It is a dynamic and often turbulent account of how faith, politics, culture, and power collided to shape one of the world’s most influential institutions. How does understanding this complex past change the way we view the foundations of our modern institutions and beliefs?
