Sharing is Caring


Throughout history, religion has been a source of unending debates, controversies, and disagreements.

The Great Schism, as it is commonly known, marked the beginning of a major religious schism that has shaped the Christian world in different ways. But why did this happen? What were the underlying reasons that caused the Christian church to split into two? This blog post will explore the history of Christianity and religious schisms, the major beliefs of Christianity, the trigger of the Great Schism, and the differences between the Roman Catholic Church and the Eastern Orthodox Church.

Whether you are a history enthusiast or just curious to know more about the religious schisms that shaped the Christian world, keep reading to unveil the mystery of why the Christian church split into two.

History of Christianity and Religious Schisms

The history of Christianity is a rich and complex tapestry that spans over two millennia. At the heart of this story lies a series of conflicts and disputes, often over matters of theology and religious practice, that have led to a number of schisms within the Church.

One of the earliest and most significant of these was the Great Schism of 1054, which resulted in the division of the Church into the Western (Roman Catholic) and Eastern (Orthodox) branches. Other schisms would follow, including the Protestant Reformation of the 16th century, which led to the establishment of a number of new denominations.

Many of these divisions were driven by differences in interpretation of the Bible, as well as disagreements over the role of the Church and its leaders. Some were also influenced by political and social factors, such as the relationship between Church and state.

Despite these schisms, however, Christianity has continued to be a powerful force in the world, with over two billion adherents today. And while the divisions between different branches of the Church remain, many Christians today are working towards greater unity and understanding between them.

Understanding the history of these schisms is essential to understanding the present state of Christianity, and the ongoing efforts to bridge the divides that have separated the Church for centuries.

Join us as we delve deeper into the fascinating history of Christianity and the religious schisms that have shaped it into the complex and diverse faith it is today.

The Early Christian Church

The origins of the Christian Church can be traced back to the 1st century AD, when Jesus of Nazareth began preaching and teaching in the region of Galilee. He attracted a large following, which continued after his death and resurrection. The followers of Jesus were first called “Christians” in Antioch, Syria, in the early 2nd century AD.

  1. Spread of Christianity: Christianity quickly spread throughout the Roman Empire, despite severe persecution by the authorities. This was due in part to the efforts of the apostles and other early Christian leaders, who travelled widely and established churches in many cities.
  2. Early Christian Doctrine: In the early years of the Church, there was much debate and disagreement over the interpretation of scripture and the nature of God. This led to the formation of various sects and factions, including the Gnostics, Marcionites, and Montanists.
  3. Formation of Church Hierarchy: As the Church grew in size and influence, a hierarchical structure developed, with bishops, priests, and deacons. This system was modeled after the Roman government, with bishops serving as the equivalent of provincial governors.
  4. First Ecumenical Council: In 325 AD, the first ecumenical council was held in Nicaea, at the behest of the Roman Emperor Constantine. The council was convened to settle the Arian controversy, which concerned the nature of Jesus and his relationship to God the Father.
  5. Emergence of Catholic and Orthodox Churches: By the 5th century AD, the Christian Church had split into two main branches: the Roman Catholic Church in the West, and the Eastern Orthodox Church in the East. The division was caused by a combination of political, cultural, and theological differences.
  6. Impact of the Early Christian Church: The early Christian Church had a profound impact on Western civilization, laying the foundation for many of the institutions and values that are still with us today. These include the concept of individual rights, the separation of church and state, and the rule of law.

The Early Christian Church was a period of rapid growth, intellectual ferment, and profound transformation. Despite the many challenges it faced, the Church succeeded in establishing itself as a major force in the world, shaping the course of history for centuries to come.

The Rise of Protestantism

The 16th century saw a significant change in the history of Christianity. It all started when a German monk named Martin Luther challenged the authority of the Roman Catholic Church. His opposition to several church doctrines and practices, including the sale of indulgences, led to the formation of the Protestant movement.

Luther’s teachings inspired others to join the movement, and soon other leaders emerged, such as John Calvin, who founded Calvinism, and Huldrych Zwingli, who founded the Swiss Reformed Church. These leaders shared a common goal: to reform the church and bring it back to its roots.

One of the key beliefs of Protestantism is justification by faith alone, which holds that salvation is obtained through faith in Jesus Christ, rather than through good works or the intercession of the church. This idea clashed with the Catholic doctrine of salvation through good works and the sacraments.

The spread of Protestantism was aided by the invention of the printing press, which allowed for the dissemination of Bibles and other religious texts in vernacular languages. This increased the accessibility of the Bible to ordinary people, who could now read and interpret the scripture for themselves.

As Protestantism grew in popularity, it led to several wars and conflicts, such as the Thirty Years’ War, which lasted from 1618 to 1648 and resulted in the death of millions of people. Despite this, the movement continued to thrive, and today, there are over 900 million Protestants worldwide.

Other Schisms in Christianity

The Christian church split into two major branches in the 11th century, but it was not the only division in Christianity. Here are some other significant schisms that have occurred:

  1. The Nestorian Schism: This schism occurred in the 5th century when Nestorius, the Patriarch of Constantinople, was accused of promoting heretical beliefs about the nature of Christ. This led to a split between the Church of the East and the rest of Christendom.
  2. The East-West Schism: This was the most significant split in Christianity, but it was not the only one. In the 16th century, the Protestant Reformation led to the establishment of many new denominations, each with its own beliefs and practices.
  3. The Anglican Schism: In the 16th century, King Henry VIII of England broke away from the Roman Catholic Church and established the Church of England. This schism was driven by political, as well as religious, factors.

Other significant schisms in Christianity include the Donatist Schism, which occurred in the 4th century in North Africa, and the Old Believer Schism, which occurred in the Russian Orthodox Church in the 17th century.

Despite these divisions, Christianity remains the world’s largest religion, with over two billion followers around the world. Understanding the history of these schisms can help us appreciate the diversity of Christian beliefs and practices, and the ways in which the religion has evolved over time.

What are the Major Beliefs of Christianity?

Christianity is one of the world’s largest religions with over 2 billion followers worldwide. It is based on the teachings of Jesus Christ, who is believed to be the Son of God. Here are the major beliefs of Christianity:

Monotheism: Christians believe in one God, who is the Creator of the universe and everything in it. God is seen as a loving and merciful God who desires a personal relationship with his creation.

Salvation: Christians believe that humans are sinful by nature and that salvation can only be obtained through faith in Jesus Christ. It is believed that Jesus died on the cross to pay the penalty for human sin and that those who accept him as their Lord and Savior will be saved.

Resurrection: Christians believe that Jesus was crucified, died, and was buried, but rose from the dead three days later. This event, known as the Resurrection, is the cornerstone of Christian faith and the source of hope for believers.

Bible: Christians believe that the Bible is the inspired word of God and serves as the ultimate authority for faith and practice. It is divided into two main parts: the Old Testament, which contains the history and teachings of the Jewish people, and the New Testament, which contains the life and teachings of Jesus Christ and the early Christian Church.

These beliefs form the foundation of Christianity and guide the way of life for believers around the world.

The Holy Trinity

The concept of the Holy Trinity is one of the foundational beliefs of Christianity, and it refers to the belief in one God in three persons: the Father, the Son (Jesus Christ), and the Holy Spirit. Here are some important points to understand about the Holy Trinity:

  • Unity in Trinity: While the three persons of the Trinity are distinct, they are also inseparable and united in one Godhead.
  • Equal in Divinity: Each person of the Trinity is equally divine, and none is greater or lesser than the others.
  • Distinct Roles: The Father is the creator of all things, the Son is the redeemer of humanity, and the Holy Spirit is the guide and comforter of believers.
  • Biblical Basis: While the term “Trinity” is not explicitly found in the Bible, the concept can be seen throughout both the Old and New Testaments.

The Holy Trinity is a central and essential doctrine of Christianity, and it serves as the basis for many other beliefs within the faith.

The Importance of Jesus Christ

Jesus Christ is central to Christian beliefs, as he is considered the Son of God and the Messiah. His life and teachings are recorded in the New Testament of the Bible, which Christians believe to be the word of God.

Christians believe that Jesus was born of a virgin, lived a sinless life, died on the cross to atone for the sins of humanity, and rose from the dead on the third day. His resurrection is seen as a triumph over death and the source of eternal life for believers.

Jesus’ teachings emphasize love, forgiveness, and compassion for others. Christians are called to follow his example and strive to live according to his teachings.

Throughout history, Jesus has been a source of inspiration for Christians, who have created art, music, and literature to honor him. Many Christians also find comfort in prayer and meditation on his teachings.

The Concept of Sin and Salvation

According to Christian belief, sin is any act that goes against the will of God, and it separates us from Him. The concept of original sin, or the belief that humanity inherited a sinful nature from Adam and Eve, is central to Christianity. Salvation, on the other hand, is the process of being saved from the consequences of sin, which is eternal separation from God. Christians believe that salvation can be achieved through faith in Jesus Christ, who died for our sins and rose from the dead.

In the Bible, it is written that “For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life” (John 3:16, NIV). This verse illustrates the importance of faith in Jesus as the path to salvation.

While there are different views on the nature of salvation among Christian denominations, the concept of sin and salvation remains central to the Christian faith. It is the belief that our sins can be forgiven and we can be reconciled with God through faith in Jesus Christ.

For Christians, the concept of sin and salvation is not just an abstract idea but has practical implications for their daily lives. It shapes their values, morals, and behaviors, and provides a sense of purpose and hope for the future.

Great Schism: What Triggered the Division of Christianity?

The Great Schism refers to the split between the Eastern Orthodox Church and the Roman Catholic Church, which occurred in the year 1054 AD.

The primary causes of the schism were theological and political differences between the two churches, including disputes over the use of icons in worship, the role of the Pope as the leader of the Christian Church, and the use of leavened bread in the Eucharist.

Another contributing factor to the Great Schism was the rise of cultural differences between the Eastern and Western Christian Churches, which had developed distinct customs, practices, and languages over the centuries.

The Great Schism had far-reaching consequences for Christianity, including the development of the Eastern Orthodox Church as a separate and distinct tradition from Roman Catholicism, and the eventual formation of Protestantism in the 16th century as a response to the perceived corruption and abuses within the Catholic Church.

The Issue of Papal Primacy

The issue of papal primacy played a significant role in the Great Schism. Papal primacy refers to the belief that the Bishop of Rome, the Pope, holds a higher rank and authority over other bishops in the Church. This concept was not accepted by the Eastern Church, which believed in the equal authority of all bishops. The Pope’s claim of authority also extended to the power to excommunicate and depose bishops, which was unacceptable to the Eastern Church. Additionally, the Eastern Church did not accept the idea of the Filioque, which was a clause added to the Nicene Creed that stated the Holy Spirit proceeded from the Father and the Son.

The issue of papal primacy had been a point of tension between the Eastern and Western Churches for centuries, but it reached a breaking point in 1054 when the Patriarch of Constantinople, Michael Cerularius, and the Pope at the time, Leo IX, excommunicated each other. This event marked the official beginning of the Great Schism and the split between the Eastern Orthodox Church and the Roman Catholic Church.

Attempts to reconcile the two Churches have been made over the years, but the issue of papal primacy remains a major stumbling block. The Orthodox Church still maintains that the Pope does not have universal jurisdiction over the entire Church and that decisions should be made through a council of bishops. The Catholic Church, on the other hand, believes that the Pope holds the highest authority in the Church and that he has the power to make binding decisions on matters of faith and morals.

The Roman Catholic Church vs. The Eastern Orthodox Church

Theological Differences: One of the main differences between the Roman Catholic Church and the Eastern Orthodox Church is their theological beliefs. For example, the Roman Catholic Church believes in the doctrine of papal infallibility, while the Eastern Orthodox Church does not. Additionally, the Roman Catholic Church accepts the Filioque clause in the Nicene Creed, which states that the Holy Spirit proceeds from both the Father and the Son, while the Eastern Orthodox Church does not accept this clause.

Doctrinal Differences: There are also doctrinal differences between the two churches. For instance, the Roman Catholic Church has seven sacraments, while the Eastern Orthodox Church has only seven. Furthermore, the Roman Catholic Church practices the use of unleavened bread for the Eucharist, while the Eastern Orthodox Church uses leavened bread.

Organizational Differences: The two churches also differ in terms of their organization. The Roman Catholic Church is led by the Pope, who is based in Vatican City, while the Eastern Orthodox Church is led by a council of bishops. Additionally, the Roman Catholic Church has a hierarchical structure, with the Pope at the top, while the Eastern Orthodox Church has a more decentralized structure.

Differences in Religious Practice

One of the major differences in religious practice between the Roman Catholic Church and the Eastern Orthodox Church is the use of icons. The Eastern Orthodox Church emphasizes the use of icons in their worship services, considering them as a powerful means of conveying spiritual truths. In contrast, the Roman Catholic Church discourages the use of icons, regarding them as a form of idolatry.

Another difference is the practice of fasting. Eastern Orthodox Christians practice fasting as a means of spiritual discipline, and abstain from meat, dairy, and other animal products on certain days of the year. In contrast, Roman Catholic Christians also practice fasting, but not to the same extent as the Eastern Orthodox Church, and they do not have strict guidelines for what can be eaten or not eaten during the fast.

Finally, the way in which the Eucharist is celebrated is different between the two churches. In the Eastern Orthodox Church, the Eucharist is typically celebrated with leavened bread, whereas the Roman Catholic Church uses unleavened bread. The Eastern Orthodox Church also administers the Eucharist by intinction, where the bread is dipped into the wine, whereas the Roman Catholic Church administers it by placing the wafer on the tongue of the communicant.

Modern Christianity: Differences Between Catholics and Orthodox Christians

Global Distribution: The Roman Catholic Church is the largest Christian denomination in the world, while the Eastern Orthodox Church has a significant presence in Eastern Europe and Russia.

Papal Authority: One of the main differences between the two is the role of the Pope. Catholics believe in the doctrine of Papal Infallibility, while Orthodox Christians believe that the Patriarch is the highest authority in their Church.

Marriage and Celibacy: Another difference between the two is the practice of celibacy among priests. Catholic priests are required to remain celibate, while Orthodox priests can be married.

The Role of the Pope

Papal Infallibility: The Catholic Church believes in the doctrine of papal infallibility, which means that the Pope is free from error when speaking on matters of faith and morals.

Papal Supremacy: The Catholic Church also holds that the Pope has supreme authority over the Church, including the power to make decisions and interpretations that are binding on all members of the Church.

Papal Primacy: In contrast, Orthodox Christians reject the idea of papal supremacy and instead believe in the concept of “first among equals,” where the Patriarch of Constantinople holds a position of honor but not supremacy among the other Orthodox leaders.
