Church History 3

From the rise of the Abbasids to the fall of Constantinople - the Great Schism, the Crusades, and how division weakened Christianity while unity preserved it.

In the name of the Father, the Son, and the Holy Spirit, one God. Amen.

We continue our journey through the centuries of Christian history, tracing how the Church endured - sometimes flourishing, sometimes suffering - but always preserved by the hand of God. In this lesson we move from the 8th century through one of the most turbulent periods in the life of the Church: the expansion of Christianity into new lands, devastating persecution in Egypt, the tragic division of 1054, the violence of the Crusades, and the fall of Constantinople to the Ottoman Turks.

Through it all, the Coptic Orthodox Church remained steadfast. While empires rose and fell, while political alliances shifted and wars raged, the faith delivered once for all to the saints was kept alive in the hearts of the faithful.


The Expansion of Christianity in the 8th and 9th Centuries

In the 8th century, a major shift took place in the Islamic world. The Abbasid dynasty replaced the Umayyads, moving the center of Islamic power from Damascus to Baghdad. This transition had consequences for Christians living under Islamic rule, but for the moment let us turn our attention westward.

In Western Europe, Charlemagne - the Frankish king - expanded his empire and with it the reach of Christianity. Through military conquest and political alliance, he brought the Christian faith to vast regions of Western and Central Europe. His coronation by the Pope in Rome on Christmas Day in the year 800 AD marked a significant moment in the relationship between the Church and political power in the West.

Meanwhile, the Byzantine Empire was actively sending missionaries into Eastern Europe. Romania, Bulgaria, and Hungary all received the Christian faith through Byzantine influence during this period. These lands adopted the liturgical and theological traditions of Constantinople, which would later be known as Eastern Orthodoxy.

Russia Receives Christianity

Perhaps the most significant missionary achievement of this era was the Christianization of Russia. Around 999 AD, Prince Vladimir of Kyiv accepted Christianity through Byzantine missionaries. According to tradition, Vladimir sent envoys to observe the worship of various religions. When his delegates visited the great church of Hagia Sophia in Constantinople, they reported that they knew not whether they were in heaven or on earth, for on earth there is no such splendor or beauty.

Russia's acceptance of Christianity through Byzantine missionaries would have lasting consequences for the shape of world Christianity. The Russian Church became one of the largest bodies within the Eastern Orthodox communion and played a decisive role in preserving the faith during centuries of hardship.


The Fatimid Period in Egypt

The 10th and 11th centuries brought a new chapter to the story of the Coptic Church in Egypt. The Fatimid dynasty established its rule, and for a time under al-Muizz, Christians experienced relative tolerance. Churches were allowed to function, and the Coptic community continued its spiritual life.

But this period of calm was shattered by the reign of al-Hakim bi-Amr Allah, who ruled from 996 to 1021 AD.


The Persecution Under al-Hakim

Al-Hakim bi-Amr Allah burned 30,000 churches - yet the Coptic cross stands firm through persecution

Al-Hakim bi-Amr Allah unleashed one of the most severe persecutions the Coptic Church has ever endured. His reign was marked by extreme cruelty toward Christians. He ordered the burning of approximately 30,000 churches across Egypt and the surrounding regions. Christians were forced to wear distinctive clothing to identify themselves publicly. Many were compelled to convert under threat of death.

The persecution extended beyond Egypt. In the year 1009, al-Hakim ordered the destruction of the Church of the Holy Sepulchre in Jerusalem - the most sacred site in all of Christendom, the very place where our Lord Jesus Christ was crucified, buried, and rose from the dead. This act of desecration sent shockwaves throughout the Christian world and would later become one of the catalysts for the Crusades.

Yet through all of this, the Coptic Church endured. The blood of the martyrs became the seed of the Church, as Tertullian had written centuries earlier. The Copts clung to their faith, their liturgy, and their identity in Christ. They proved once again that no persecution - no matter how severe - can extinguish the light of the Gospel.

As our Lord promised:

"I will build My church, and the gates of Hades shall not prevail against it." - Matthew 16:18


The Great Schism of 1054

The Great Schism of 1054 - Rome and Constantinople divide over the Filioque, creating three families of churches

While the Coptic Church was enduring persecution in Egypt, a different kind of tragedy was unfolding between the churches of Rome and Constantinople. In the year 1054, the Great Schism formally divided Western and Eastern Christianity.

The immediate cause was the addition of the Filioque clause to the Nicene Creed by the Western Church. The original Creed, as affirmed by the Ecumenical Councils, states that the Holy Spirit "proceeds from the Father." Rome added the phrase "and the Son" (in Latin, Filioque) without the consent of an ecumenical council. Constantinople rejected this addition as unauthorized and theologically problematic.

But the Filioque was only the surface issue. Beneath it lay centuries of growing tension over papal authority, liturgical differences, and political rivalry between Rome and Constantinople. When Cardinal Humbert placed a bull of excommunication on the altar of Hagia Sophia, and the Patriarch of Constantinople excommunicated the papal legates in return, the breach became official.

Three Families of Churches

It is important for us as Coptic Orthodox Christians to understand the distinction between the three major families of churches that emerged from these divisions:

  1. The Oriental Orthodox Churches - including the Coptic, Ethiopian, Eritrean, Syrian, Armenian, and Indian Orthodox Churches. Our separation from the rest of Christendom occurred at the Council of Chalcedon in 451 AD over the Christological definition - not over the Filioque or papal authority. We hold to the one united nature of the incarnate Word, as taught by St. Cyril of Alexandria, the 24th Pope of Alexandria.

  2. The Eastern Orthodox Churches - the Greek, Russian, Romanian, Serbian, and other churches that follow the Byzantine tradition. They separated from Rome in 1054 over the Filioque and papal supremacy.

  3. The Roman Catholic Church - the Western church centered on the papacy in Rome.

Each of these separations weakened the visible unity of the Body of Christ. While we believe that the Coptic Orthodox Church has faithfully preserved the apostolic faith, we also recognize the tragedy of division within Christianity. Our Lord prayed:

"That they all may be one, as You, Father, are in Me, and I in You; that they also may be one in Us, that the world may believe that You sent Me." - John 17:21


The Crusades

The Crusades - Christians against Christians, with the Copts caught in the middle of the conflict

The destruction of the Church of the Holy Sepulchre by al-Hakim, combined with reports of persecution against Christian pilgrims in the Holy Land, eventually led to one of the most controversial chapters in Christian history - the Crusades.

Beginning in 1099 and lasting approximately 200 years, the Crusades involved at least twelve major military campaigns launched by Western European Christians with the stated goal of reclaiming the Holy Land from Muslim control.

Christians Against Christians

The tragedy of the Crusades is not merely that they involved violence in the name of Christ - a contradiction of everything He taught - but that they also targeted fellow Christians. On their way to the Holy Land, the Crusaders infamously sacked Constantinople itself in 1204, looting churches, destroying sacred relics, and killing Eastern Christians. This was Christians killing Christians - an unspeakable scandal.

The Copts Caught in the Middle

The Crusaders' presence in the region brought no relief to the Coptic Church. In fact, the Copts suffered persecution from both sides. The Muslims viewed them with suspicion as potential allies of the Western invaders, while the Crusaders - who followed the Roman Catholic faith - often treated the Oriental Orthodox as heretics.

When Saladin defeated the Fatimids and established the Ayyubid dynasty, he fought the Crusaders for control of the region. During one of the later Crusades, King Louis IX of France was captured at Damietta in Egypt. The Copts bore the consequences of this conflict, persecuted by both the Muslim rulers and the Western invaders.

The Crusades demonstrated a painful truth: when the Church abandons the way of the cross - the way of humility, love, and self-sacrifice - and takes up the sword, it betrays its own Lord. As Christ told Peter:

"Put your sword in its place, for all who take the sword will perish by the sword." - Matthew 26:52


The Fall of Constantinople

The final act of this chapter in church history came in 1453, when Constantinople - the great city of Constantine, the capital of the Byzantine Empire for over a thousand years - fell to the Ottoman Turks under Sultan Mehmed the Conqueror.

The great cathedral of Hagia Sophia, which had been the crown jewel of Eastern Christianity for nine centuries, was converted into a mosque. The city itself was renamed Istanbul, and it became the capital of the Ottoman Empire.

The fall of Constantinople was a devastating blow to Eastern Christianity. The city that had been the seat of the Ecumenical Patriarch, the center of Byzantine culture and theology, and a symbol of Christian civilization was now in Muslim hands.

The Ottoman Expansion

The Ottomans did not stop at Constantinople. They expanded into Eastern Europe, conquering Bosnia, Kosovo, and other territories. In 1517, the Ottomans conquered Egypt from the Mamluks, bringing the Coptic Church under yet another Islamic dynasty.

For the Copts, the change from Mamluk to Ottoman rule meant new overlords but the same fundamental reality - a Christian minority living under Islamic governance, clinging to the faith of their fathers, preserved by God's grace through every trial.


Lessons for the Evangelist

What can we learn from this period of history as we seek to share the Gospel today?

First, division weakens the witness of the Church. The Great Schism, the Crusades, and the mutual suspicion between Christian communities all contributed to the weakening of Christianity as a whole. When the world sees Christians fighting one another, it has little reason to believe our message of love and reconciliation.

Second, unity preserves the faith. Consider Russia. When it received Christianity as a unified faith from Byzantine missionaries, the Gospel took deep root. The Russian Church survived centuries of Mongol invasion, political upheaval, and later Communist persecution precisely because the faith was planted with strength and unity.

Third, persecution cannot destroy the Church. Al-Hakim burned 30,000 churches. The Crusaders sacked Constantinople. The Ottomans conquered city after city. And yet the Church survived - in Egypt, in Constantinople (even under Ottoman rule), in Russia, and throughout the world. The gates of Hades did not prevail.

Fourth, the way of the cross - not the way of the sword - is the true path of the Gospel. The Crusades stand as a warning against confusing political power with spiritual mission. The evangelist carries the cross, not a weapon. The evangelist conquers through love, not through force.

As St. Paul wrote:

"For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds." - 2 Corinthians 10:4


Conclusion

The centuries we have studied today were among the most turbulent in Christian history. Empires rose and fell. Churches were burned and rebuilt. The visible unity of the Church was shattered into three major families. The Crusades left a legacy of violence and mistrust. Constantinople, the great bastion of Eastern Christianity, fell to the Ottomans.

And yet through it all, the Church endured. The Coptic Orthodox Church - our Church - survived every persecution, every political upheaval, every attempt to extinguish its light. Why? Because the Church does not belong to any empire or dynasty. The Church belongs to Christ. And He has promised that He will be with us always, even to the end of the age.

Let us take this confidence with us as we evangelize. The faith we share is not a fragile thing. It has been tested by fire for two thousand years and has never been found wanting. We stand on the shoulders of martyrs, confessors, and saints who gave everything so that we might receive the faith. Let us be worthy of their sacrifice.
