Have you ever been intrigued by ancient Christian practices? Perhaps you’ve seen stunning golden-domed churches or encountered vibrant, captivating icons. If so, you might be wondering about the rich and mystical world of Exploring Orthodox Christianity. It’s often called the Eastern Orthodox Church. This branch of Christianity represents one of the oldest continuous Christian traditions on Earth. It boasts a profound history, deeply rooted beliefs, and a unique approach to worship that speaks to the senses and the soul.
Unlike some Western Christian denominations that have undergone significant changes over the centuries, Orthodox Christianity emphasizes continuity with the early Church. Here, tradition isn’t just history. It’s a living, breathing stream connecting today’s believers with the Apostles and early Church Fathers. In this guide, we’ll begin Exploring Orthodox Christianity by delving into its history, core beliefs, cherished traditions, and the awe-inspiring experience of its worship.
Understanding the Roots of Orthodox Christianity
To truly appreciate Exploring Orthodox Christianity, you must understand its historical journey. Initially, the Christian Church was united. However, theological, cultural, and political differences gradually emerged between the Greek-speaking East and the Latin-speaking West.
The Historical Journey of the Eastern Orthodox Church
The “Great Schism” of 1054 marks the most significant event in Orthodox Christianity’s history. This pivotal moment saw the formal split between the Church in the East, centered in Constantinople, and the Church in the West, centered in Rome. Earlier tensions existed. But 1054 brought mutual excommunication. This led directly to the formation of what we now know as the Eastern Orthodox Church and the Roman Catholic Church. Furthermore, the Eastern Church continued developing its theology and practices. It based them on the Ecumenical Councils held primarily in the East.
Key Theological Differences in Orthodox Beliefs
Orthodox Christianity shares many fundamental Christian doctrines with the West. These include the Trinity and Christ’s divinity. Yet, it also reveals some distinct theological emphases and differences.
- The Filioque Clause: This is perhaps the most famous point of contention. The West added the phrase “and the Son” (filioque) to the Nicene Creed. This stated the Holy Spirit proceeds from the Father and the Son. Conversely, the Orthodox Church maintains the original Creed. It states the Holy Spirit proceeds solely from the Father. The Orthodox Church views the Filioque addition as both unauthorized and theologically problematic.
- Papal Authority: The Orthodox Church does not accept the doctrine of universal papal jurisdiction or infallibility. Roman Catholicism defines these doctrines differently. Instead, Orthodox churches organize themselves as a communion of self-governing (autocephalous) churches. The Ecumenical Patriarch of Constantinople holds a place of honor among them, but not absolute authority over others.
- Theosis (Deification/Divinization): While Western thought knows theosis, it is a central concept in Orthodox Spirituality. It refers to the transformative process where believers become more like God. This happens through God’s grace, prayer, and participating in the Sacraments. Believers become partakers of the divine nature (2 Peter 1:4). Theosis represents the ultimate goal of the Christian life.
Core Beliefs in Orthodox Christianity
A deep well of theological understanding lies at the core of Orthodox Christianity. It roots itself in Scripture and the consistent teaching of the Church throughout the ages. This body of teaching is known as Holy Tradition.
The Doctrine of Theosis in Orthodox Theology
As mentioned, theosis is paramount. It is not about becoming God in His essence. Rather, it’s about participating in His divine energies or grace. This transformative journey involves purification, illumination, and ultimately, glorification. Purification means overcoming passions. Illumination means receiving divine light. Glorification leads to union with God. This understanding profoundly shapes Orthodox asceticism, prayer life, and the view of salvation.
Scripture and Holy Tradition in the Orthodox Faith
Orthodox Christianity quickly reveals how important both Holy Scripture (the Bible) and Holy Tradition are. Tradition isn’t separate from Scripture. Instead, the Church sees it as the context within which believers properly understand and live out Scripture. This includes teachings from the Ecumenical Councils. It also encompasses writings of the Church Fathers, the Church’s liturgical life, canon law, and even iconography. Therefore, Tradition represents the living faith the Church passes down through generations.
The Trinity and Christology in Orthodox Belief
Orthodox belief fully affirms the Nicene Creed’s teaching on the Trinity. This involves one God in three co-eternal, co-equal Persons: Father, Son, and Holy Spirit. Similarly, Orthodox Christology firmly upholds Christ’s two natures – fully God and fully human. They unite in one Person. This union happens without confusion, change, division, or separation. The Council of Chalcedon defined this doctrine clearly.
Traditions and Practices of Orthodox Christianity
Daily life and spiritual discipline are integral to Orthodox Christianity. Traditions and practices are not mere rituals. Instead, the Church sees them as pathways to communion with God and participation in His life.
The Role and Reverence of Icons in Orthodox Tradition

Icons are much more than religious art in Orthodox Christianity. The Church considers them “windows to heaven,” visual Gospels, and aids to prayer. Orthodox theology defends venerating icons. This shows deep respect and honor, not worship. The Church sees them as tangible links to the spiritual reality of the saints and Christ they depict. Believers keep them in churches and homes. Furthermore, they kiss them as a sign of love and respect for the person represented.
Fasting and Feasts in Orthodox Practice
Cycles of fasting and feasting mark the Orthodox year. The Church sees fasting periods as spiritual disciplines. These include Great Lent before Pascha (Easter), the Nativity Fast before Christmas, and shorter fasts for Apostles’ and Dormition Fasts. Fasting helps believers curb passions and focus on God. Conversely, feasts are joyous celebrations of key events. They honor events in the lives of Christ, the Theotokos (Mother of God), and the Saints. These rhythms shape the faithful’s spiritual journey.
The Sign of the Cross and Other Orthodox Customs
Orthodox Christians typically make the sign of the cross frequently. They join the thumb and first two fingers, symbolizing the Trinity. They then touch the forehead, chest, right shoulder, then left shoulder. This invokes the Trinity upon the mind, heart, and strength. Other customs include using prayer ropes (komvoskini/chotki). Believers also light candles as offerings. They frequently receive blessings from clergy.
Worship: The Divine Liturgy in Orthodox Christianity
The central act of worship in Orthodox Christianity is the Divine Liturgy. It is a profound, sensory, and corporate experience. The Church sees it as bringing heaven to earth.

Experiencing the Divine Liturgy in Orthodox Worship
Attending an Orthodox Liturgy can be overwhelming yet deeply moving. It involves chanting, incense, elaborate vestments, and standing for much of the service. The service focuses on offering the Eucharist (Holy Communion). However, the entire service is also a journey. It reenacts salvation history, culminating in receiving Christ’s Body and Blood. It stands as a corporate prayer of the entire community. This includes the saints and angels.
Sacraments (Mysteries) in Orthodox Christianity
The Orthodox Church refers to Sacraments as “Mysteries.” This emphasizes their divine and mysterious nature. The Church’s life is permeated by God’s grace. While believers typically identify seven major Mysteries, divine grace works throughout the Church’s life. The main Mysteries are:
- Baptism: Entry into the Church. It signifies new life in Christ.
- Chrismation (Confirmation): This occurs immediately following Baptism. It signifies receiving the gift of the Holy Spirit.
- Holy Eucharist (Communion): Believers receive the Body and Blood of Christ here. This happens for the forgiveness of sins and eternal life. It is the central Mystery.
- Confession (Penance): This involves repentance and forgiveness of sins. It comes through Christ, mediated by the priest.
- Marriage: This represents a union blessed by God. It serves as a path to theosis.
- Holy Orders (Ordination): This involves setting apart individuals for ministry. They serve as deacons, priests, and bishops.
- Holy Unction: This involves anointing with oil. It is for the healing of soul and body.
