Orthodox Vs Catholic: What's The Difference?

how does greek orthodox differ from catholic

The Greek Orthodox Church and the Catholic Church are two distinct Christian denominations with a number of theological differences. The two churches have been officially separated since the East-West Schism of 1054, caused by historical, linguistic, and theological differences. The key differences between the two churches include the role of the Pope, the interpretation of the Holy Trinity, the concept of purgatory, and the understanding of transubstantiation and the Eucharist. Despite these differences, both churches have maintained friendly bilateral relations and share similarities in their sacraments.

The role of the Pope

The Pope's role encompasses several key functions. He is the supreme pastor of the global Catholic faithful, believed to possess the power to define doctrine and make disciplinary decisions for the entire church. This authority is derived from the concept of papal infallibility, which dictates that the Pope is preserved from the possibility of error when he teaches dogma in an official definition. The Pope is also the Bishop of Rome and holds immediate jurisdiction over the diocese of Rome, as well as being the sovereign of Vatican City State.

As the leader of the Catholic Church, the Pope appoints all bishops, who in turn appoint priests to serve in local parishes. This hierarchical structure ensures unity and consistency in the teachings and practices of the Catholic faith worldwide. The Pope also serves as the final arbiter in matters of doctrine and discipline, with the power to interpret and define the faith's teachings. This includes the ability to issue official documents known as encyclicals, which provide guidance and instruction on moral and social issues.

Another important aspect of the Pope's role is his primacy within the College of Bishops. While the College of Bishops as a whole possesses authority to govern the Church, the Pope serves as its head and can exercise his authority independently of the college. This includes the power to call and lead ecumenical councils, which are gatherings of bishops meant to discuss and decide upon church doctrine and discipline.

The Pope is also responsible for the diplomatic relations of the Holy See, the central governing body of the Catholic Church, with other nations and international organizations. He appoints diplomatic representatives, known as Apostolic Nuncios, to maintain relations with other countries and the United Nations. The Pope himself often engages in diplomatic activities, such as negotiating agreements, advocating for peace, and addressing social and moral issues on a global scale.

Finally, the Pope is also considered the supreme interpreter of the sacred liturgy of the Catholic Church. He regulates the sacraments and approves translations of liturgical texts. The Pope's decisions and interpretations in this area are considered authoritative and are followed by Catholics worldwide, contributing to the unity and consistency of Catholic worship.

The Filioque clause

The Eastern Orthodox Church considers this addition heretical, asserting that the correct procession is "from the Father alone", which they view as a fundamental dogma. They argue that the Filioque clause subordinates the Holy Spirit to the Father and the Son, disrupting the balance of the Holy Trinity by placing the Son above the Holy Spirit. The Orthodox interpretation of the Trinity maintains that the Holy Spirit has his origin or being from the Father alone, with the Father as the uncaused and unoriginate God.

The addition of the Filioque clause to the Creed was done without an Ecumenical Council, and the Eastern Church saw it as an unauthorized alteration. The Fourth Council of Constantinople in 879, considered ecumenical by some Eastern Orthodox, included a clause prohibiting any additions to the Creed. By 1014, Rome had begun reciting the Creed with the Filioque, causing tension with the East.

The Western Church, including Rome, defended the addition as a necessary clarification to address heretical distortions, particularly Arianism, and to emphasize the equality of the Father and the Son in the Trinity. They argued that the Filioque was consistent with their theology and did not constitute a new creed.

Despite the historical dispute, the Filioque is considered a non-issue by some modern Catholics, and it is not emphasized in their religious education or used as a theological weapon against the Orthodox. Additionally, the Eastern Catholic churches and Greek versions of the Creed do not include the Filioque.

The concept of purgatory

The Catholic Church and the Eastern Orthodox Church have had significant differences since the East-West Schism of 1054. One of the key differences between the two denominations is their belief in the concept of purgatory.

The Catholic Church teaches that, after death, the souls of Christians deemed pure by God are sent to paradise, while those weighed down by mortal sins are sent to Hades. Additionally, Catholics believe in the existence of purgatory, a state between paradise and Hades. In purgatory, Catholics believe that souls undergo temporary punishment for their sins, after which they are allowed into heaven. This belief is based on the understanding that while Christ paid the eternal penalty for sin on the Cross, individuals must still pay a temporal penalty. Catholics cite passages from the Bible, such as Matthew 12:32 and I Corinthians 3:13, to support this interpretation.

In contrast, the Orthodox Church does not accept the idea of purgatory in the same way as Catholics. They argue that the concept of purgatory lacks scriptural basis and is not found in the original Scriptures. Instead, the Orthodox community views the intermediate state after death as a foretaste of either eternal reward or punishment, determined on the Day of Judgment. The Orthodox Church emphasizes the prayers and intercession of the faithful for the dead, believing that these can bring alleviation or release from torments.

The differences in the understanding of purgatory between the Catholic and Orthodox Churches have been a topic of debate for centuries, with the two sides holding distinct interpretations of Scripture and the nature of sin, punishment, and forgiveness.

Despite these differences, it is important to note that both the Catholic and Orthodox Churches share similarities in their beliefs about the afterlife, and they both recognize the importance of prayer and repentance for the dead.

The language used

The use of Greek in the Greek Orthodox Church is rooted in history and tradition. It is the language of the New Testament and was the common language of the early Christian world. Greek is still used today in the Greek Orthodox liturgy, which has remained largely unchanged for centuries. The Greek language is considered sacred and is believed to have a special connection to the faith and theology of the Orthodox Church.

In contrast, the Catholic Church has historically used Latin as its liturgical language. This tradition began in the Western Church during the time of the Roman Empire, when Latin was the common language of the region. Even after the fall of Rome, Latin remained the language of the Catholic Church, and it played a significant role in shaping the theology and doctrine of the Church.

However, in more recent times, the Catholic Church has also incorporated the use of local languages in its liturgy. This change began with the Second Vatican Council in the 1960s, which sought to increase participation and understanding of the mass by allowing prayers and readings to be translated into local languages. Today, it is common for Catholic masses to be conducted in the language of the local congregation, with Latin still being used for certain traditional prayers and chants.

The difference in language used in the liturgies of the Greek Orthodox and Catholic Churches has had an impact on the cultural and theological development of each tradition. The use of Greek in the Orthodox Church has helped to preserve the ancient traditions and theology of the early Church, while the use of Latin in the Catholic Church has contributed to a more unified and consistent expression of Catholic doctrine across the globe.

Despite these differences, both the Greek Orthodox and Catholic Churches recognize the importance of language in worship and strive to balance the use of traditional and modern languages to ensure that the liturgy is accessible and meaningful to their congregations.

The Eucharist

In terms of the Eucharist itself, the Greek Orthodox Church uses leavened bread, which symbolises the risen Christ. In contrast, Roman Catholics use unleavened bread, which represents the Last Supper. The use of leavened bread in the Greek Orthodox Church is part of their retention of many ancient Christian traditions. The bread and wine are treated with great respect and reverence by both Catholics and Orthodox Christians, and the Eucharist is central to both denominations.

Theologically, the Greek Orthodox Church emphasises mysticism and theosis (deification), focusing on experiential faith. They believe in the "'real presence' of Christ in the Eucharist but do not limit this presence solely to the Eucharist itself. They see Christ's presence as a Mystery that defies complete rational explanation. On the other hand, Roman Catholics place more emphasis on doctrinal teachings and the interpretation of Scripture. They have a more detailed doctrine of transubstantiation, formulated after the Great Schism of 1054, which explains the transformation of the bread and wine into the body and blood of Christ.

The Greek Orthodox Church does not have a central authority figure like the Pope in the Catholic Church. Instead, it is led by a group of autocephalous patriarchs and bishops who emphasise collective decision-making. This difference in church governance also influences the liturgy and rituals of each denomination. Greek Orthodox liturgy is traditionally in ancient Greek and is highly ceremonial, with a significant emphasis on icons. Catholic masses, however, are typically conducted in the local language and are less reliant on icons.

Despite these differences, there are also many similarities and shared beliefs between the two denominations regarding the Eucharist. Both recognise the importance of the Eucharist as a means of grace and unity among Christians. The Eucharist is a sacred moment in both traditions, bringing together communities of faith and allowing them to participate in the sacrifice and presence of Christ.
