For those curious about Christianity’s ancient roots, Orthodox Christianity often stands as a profound and beautiful expression of the faith. It’s one of the oldest branches of Christianity, yet it remains unfamiliar to many in the Western world. Whether you're a seeker, a new convert, or just exploring, this Orthodoxy 101 guide will help you understand the essentials of the Eastern Orthodox Church—its beliefs, practices, and unique traditions.
What Is Eastern Orthodoxy?
Eastern Orthodoxy is one of the three main branches of Christianity, alongside Roman Catholicism and Protestantism. Rooted in the early Church and the teachings of the Apostles, it preserves ancient Christian traditions and theology. The word "Orthodox" means "right belief" or "correct worship", reflecting the Church's commitment to maintaining the true faith handed down over centuries.
The Orthodox Church does not have a single central authority like the Pope in Catholicism. Instead, it consists of several autocephalous (self-governing) churches, such as the Greek Orthodox, Russian Orthodox, Serbian Orthodox, and others, all united in faith and sacraments.
Key Beliefs in Orthodoxy
The Holy Trinity
Orthodox Christians believe in one God in three persons: Father, Son, and Holy Spirit—equal and eternal. This foundational belief is shared with other Christian traditions.Jesus Christ
Jesus is both fully divine and fully human. His incarnation, death, and resurrection are central to salvation. Orthodox theology emphasizes Christ’s victory over death, rather than just atonement for sin.The Bible and Holy Tradition
Orthodox Christianity sees the Bible as divinely inspired but not the sole source of authority. Holy Tradition, which includes the writings of the Church Fathers, Ecumenical Councils, liturgical worship, and more, is equally important.Salvation as Theosis
Orthodox Christians believe that the goal of life is theosis—union with God. Salvation is not just about being saved from sin, but being transformed into the likeness of Christ through a life of repentance, prayer, and love.
Worship and Liturgy in Orthodoxy
Worship is at the heart of Orthodox life. The primary service is the Divine Liturgy, celebrated every Sunday and on feast days. It includes Scripture readings, hymns, prayers, and most importantly, the Eucharist (Holy Communion).
Orthodox worship is highly sensory and symbolic:
Icons (holy images) are venerated, not worshipped.
Incense, chanting, and candles create a heavenly atmosphere.
Standing during the service is common, reflecting reverence.
The Seven Sacraments
Like Catholicism, Orthodoxy recognizes seven sacraments (called "Holy Mysteries"):
Baptism – Entry into the Church, usually done by full immersion.
Chrismation – Anointing with oil to receive the Holy Spirit (done right after baptism).
Eucharist – Holy Communion, the Body and Blood of Christ.
Confession – The sacrament of repentance and forgiveness.
Marriage – A sacred union blessed by the Church.
Holy Orders – Ordination of clergy.
Unction – Anointing of the sick for healing.
Key Practices of Orthodox Life
Prayer and Fasting
Orthodox Christians are called to daily prayer and frequent fasting, particularly during the four major fasts of the Church (Great Lent, Nativity Fast, Apostles' Fast, and Dormition Fast).Feast Days
The Orthodox liturgical calendar is filled with feast days commemorating events in Christ's life, the Theotokos (Mother of God), and the saints. The greatest feast is Pascha (Easter), celebrating Christ’s Resurrection.Icons and Saints
Icons are more than art—they are windows into heaven. Saints are honored as examples of holiness and are believed to intercede for the living.
