Orthodox Christianity, commonly known as the Eastern Orthodox Church, is one of the oldest continuous expressions of the Christian faith. Rooted directly in the teachings of Jesus Christ and the apostles, Orthodox Christianity emphasizes preserving the original beliefs, worship, and spiritual life of the early Christian Church.
Today, Orthodox Christianity is practiced by millions of believers worldwide, particularly in Eastern Europe, the Middle East, Africa, and growing communities in the United States.
What Does “Orthodox” Mean?
The word Orthodox comes from the Greek orthodoxia, meaning “right belief” or “right worship.” This reflects the Church’s commitment to maintaining authentic Christian doctrine and liturgical life as handed down through Scripture and Holy Tradition.
Core Beliefs of Orthodox Christianity
Orthodox Christianity is grounded in classical Christian theology, with several distinctive emphases.
Belief in the Holy Trinity
Orthodox Christians believe in one God in three persons:
- The Father
- The Son
- The Holy Spirit
This belief is formally expressed in the Nicene Creed, recited during worship services.
Jesus Christ: Fully God and Fully Human
Orthodox Christianity teaches that Jesus Christ is both fully divine and fully human, united without confusion or division. His incarnation, crucifixion, and resurrection are central to human salvation.
Salvation as Transformation (Theosis)
Rather than focusing only on legal forgiveness, Orthodox Christianity emphasizes theosis—the process of becoming united with God through grace, prayer, and participation in the sacramental life of the Church.
Scripture and Holy Tradition
Orthodox Christians hold the Bible and Holy Tradition together as authoritative. Tradition includes:
- Teachings of the Church Fathers
- Decisions of Ecumenical Councils
- Liturgical worship and practices
Worship and Spiritual Life in Orthodox Christianity
Orthodox worship is deeply liturgical, communal, and sensory.
The Divine Liturgy
The central worship service is the Divine Liturgy, where believers receive the Eucharist (Holy Communion). Worship includes chanting, Scripture readings, prayers, incense, and icons.
The Sacraments (Holy Mysteries)
Orthodox Christianity recognizes seven sacraments, often called Holy Mysteries:
- Baptism
- Chrismation (Confirmation)
- Eucharist
- Confession
- Marriage
- Holy Orders
- Anointing of the Sick
Icons and Sacred Art
Icons are not worshiped but venerated as windows into heaven, helping believers focus on Christ, the saints, and the life of God.
Prayer and Fasting
Spiritual disciplines include:
- Daily prayer (including the Jesus Prayer)
- Regular fasting seasons such as Great Lent
- Observance of feast days and saints’ commemorations
Church Structure and Leadership
Orthodox Christianity does not have a single central authority like the Pope. Instead, it is a communion of self-governing (autocephalous) churches, united in faith and sacramental life.
Major Orthodox churches include:
- The Greek Orthodox Church
- The Russian Orthodox Church
- The Serbian Orthodox Church
- The Antiochian Orthodox Church
Each church is led by bishops, with the Ecumenical Patriarch of Constantinople recognized as first among equals, not as a supreme ruler.
A Brief History of Orthodox Christianity
Orthodox Christianity developed in the eastern part of the Roman Empire. A major turning point came in 1054 AD, known as the Great Schism, which separated Eastern Orthodox Christianity from Roman Catholicism due to theological, cultural, and authority-related differences.
Since then, the Orthodox Church has preserved its ancient liturgy, theology, and spiritual practices with minimal change.
Orthodox Christianity Today
Today, Orthodox Christianity continues to grow globally, attracting many converts seeking:
- Historical continuity with the early Church
- Deep, reverent worship
- A strong emphasis on spiritual transformation and community
Orthodox parishes can now be found across North America, Western Europe, and beyond.
