The Great Schism

Estrangement Between East and West

  • Fundamental Reasons

    • Long-standing estrangement began in the second century.
    • Ecclesiastical centers: Multiple in the East vs. one in the West.
    • Language disparity: Dominance of Latin in the West for intellectual discourse, while the East maintained more diversity.
    • Political instability in the East due to loss of control.
    • Gradual collapse of Roman rule in the West replaced by tribal cultures leading to primitive nation-states.
    • Greater cultural, political, and social stability in the East than in the West.

  • Historical Context

    • End of the Roman Empire's political control, particularly in the West.
    • Impact of invasions and tribal formations on the political landscape.

The Great Schism and Key Individuals

  • Overview of Schism

    • Permanent break between Eastern Orthodox (Byzantine) and Roman Catholic Churches.
    • Major figures involved:
    • Michael Cerularius: Patriarch of Constantinople
    • Pope Leo IX: Bishop of Rome
    • Cardinal Humbert: Papal legate, sent to negotiate.
    • Constantine IX: Byzantine Roman Emperor.

  • Key Issues Leading to the Schism

    • Filioque Clause:
    • Unofficial addition to the Nicene Creed by Rome; states the Holy Spirit proceeds from both the Father and the Son.
    • Originated around 50 years before the breach, controversial and rejected by the East.
    • Importance of the clause tied to the understanding of the nature of Christ and the Trinity.

Conflict Escalation

  • Papal Actions and Letters

    • Pope Leo IX's decree: Demanded Southern Italian Greek churches adopt Latin liturgy and unleavened bread for Eucharist.
    • Patriarch Cerularius retaliated by enforcing Greek liturgy and leavened bread in Latin churches in Constantinople.

  • Cardinal Humbert's Mission

    • Humbert's mission met with resistance; he openly debated the differences in customs, particularly on Eucharistic practices.
    • Conflict escalated with Humbert accusing the East of doctrinal errors, leading to excommunication of Cerularius and the emperor.
    • Performance of excommunication in Hagia Sophia symbolized the deepening rift.

Consequences of the Schism

  • Long-term Implications

    • After excommunications, no communication between Eastern and Western Churches for approximately 150 years.
    • Gradual emergence of differences in practices, beliefs, and the focus on political power.

  • The Crusades and Further Conflicts

    • Western Crusades diverted to Constantinople in 1204, leading to violence and plundering, further alienating Eastern Christians.
    • Events characterized by Christians attacking Christians, leading to a significant loss of trust.

Attempts at Reconciliation

  • Later Church Councils
    • Council of Lyon (1274): Attempted to reunify churches; unsuccessful.
    • Council of Florence (1438-1445): Some Eastern bishops signed agreement recognizing papal primacy and the Filioque, but widespread acceptance absent.

Differences Between Eastern Orthodoxy and Roman Catholicism

  • Theological Divergences

    • Differences in the concept of the Nicene Creed.
    • Western adoption of purgatory and original sin concepts.
    • Theosis vs. salvation views differing significantly.
    • Development of a treasury of merits in Roman Catholicism.

  • Jurisdictional Authority

    • Claims by the Bishop of Rome over all churches vs. local authority in the East.
    • Developments in celibacy rules for clergy differing between Churches.

  • Liturgy Practices

    • Use of Latin in the West vs. vernacular languages in the East.
    • Liturgy conduct regulations being more diverse in East compared to the strict Latin use in the West until Vatican II.

Political Landscape and Evolution

  • Political Instability in the West

    • Invasions during the 3rd and 4th centuries leading to weakened Roman political structure.
    • Notable incidences, such as the Battle of Adrianople leading to the fall of the Western Roman Empire.

  • Rise of New Dynasties

    • Emergence of the Holy Roman Empire post-barbarian invasions.
    • The role of kings like Clovis in unifying regions under Christianity was pivotal.
    • Issues related to lay investiture became significant in the power struggles between church and state.

  • Conflicts with Political Figures

    • Bishop Leo the Great's negotiation to save Rome.
    • Conflict between Pope Gregory VII and Henry IV over appointments revealed the intertwining of political power and church authority.
