The Faith
What We Believe
The Orthodox Christian faith is not a set of opinions. It is a living encounter with the living God — Father, Son, and Holy Spirit.
Ἰησοῦς Χριστός
Jesus Christ
Jesus Christ is the eternal Son of God — fully divine and fully human — who took on flesh, was born of the Virgin Mary, suffered, died on the Cross, and rose from the dead on the third day. He is not a great teacher who became divine, nor a divine being who only appeared human. He is both, without confusion, without change, without division, without separation.
This is the definition of the Council of Chalcedon (451 AD), and it remains the heart of Orthodox Christology. The Incarnation — God becoming man — is not merely the means of our salvation. It is salvation itself. In Christ, human nature is united to divine nature, and through Him, we are invited into that union.
Key term
Theanthropos
The God-Man — the technical theological term for Christ's two natures in one Person.
Ἁγία Τριάς
The Holy Trinity
God is one in essence and three in Persons: Father, Son, and Holy Spirit. The Trinity is not three gods, nor one God wearing three masks. The Father is not the Son; the Son is not the Spirit; the Spirit is not the Father — yet they are one God, one will, one love, one life.
Orthodox theology speaks of the divine essence (ousia) — what God is — and the divine energies (energeiai) — how God acts and is truly known. We cannot know God's essence directly, but through His energies — His grace, His light, His love — we genuinely encounter God Himself, not merely a representation of Him.
Key term
Perichoresis
The mutual indwelling of the three Persons of the Trinity — each fully present in the others, in perfect communion.
Ἁγία Γραφή
Holy Scripture
The Orthodox Church receives Holy Scripture as the inspired Word of God — the Old and New Testaments together, including the deuterocanonical books (Tobit, Judith, Wisdom, Sirach, Baruch, 1–2 Maccabees) that were part of the Septuagint, the Greek translation used by the Apostles and the early Church.
Scripture is not read in isolation. It is read within the Church, through the lens of Holy Tradition — the continuous life of the Holy Spirit in the Body of Christ. The Fathers, the Councils, the Liturgy, and the saints are all witnesses to the same faith the Apostles received and handed on.
Key term
Septuagint (LXX)
The Greek translation of the Hebrew scriptures, completed before Christ, used by the Apostles and quoted throughout the New Testament.
Ἱερά Παράδοσις
Holy Tradition
Holy Tradition is not a collection of customs added to Scripture. It is the living memory of the Church — the continuous, unbroken transmission of the faith from the Apostles to the present day. Scripture itself is part of Holy Tradition: it was written within the Church, recognized by the Church, and has always been interpreted within the Church.
Tradition includes the Ecumenical Councils, the writings of the Church Fathers, the Divine Liturgy, the canons, the iconographic tradition, and the lives of the saints. None of these are additions to the faith. They are expressions of the one faith, received once and for all.
Key term
Paradosis
The Greek word for Tradition — literally, 'that which is handed over.' The same word St. Paul uses in 1 Corinthians 11:23: 'I received from the Lord what I also handed on to you.'
Σωτηρία & Θέωσις
Salvation & Theosis
In Orthodox theology, salvation is not primarily a legal transaction — a debt paid, a penalty transferred. It is healing, restoration, and union. Sin is understood as a sickness of the soul, a turning away from God who is Life. Christ came not only to forgive sins but to destroy death and restore human nature to its intended fullness.
The goal of the Christian life is theosis — deification, or union with God. 'God became man so that man might become god,' wrote St. Athanasius. This does not mean we become God by nature, but that we participate in the divine life, the divine energies, by grace. Theosis begins in this life through prayer, the sacraments, fasting, repentance, and love.
Key term
Theosis
Deification — the process by which a human person is united to God and participates in the divine life by grace. The ultimate purpose of human existence.
Σύμβολον τῆς Πίστεως
The Nicene Creed
The Nicene-Constantinopolitan Creed (325/381 AD) is the universal statement of Christian faith, recited at every Divine Liturgy. It was not composed by committee — it was drawn from Scripture and the living faith of the Church, in response to heresies that threatened to distort the identity of Christ and the Holy Spirit.
Πιστεύω εἰς ἕνα Θεόν,
I believe in one God,
Πατέρα, Παντοκράτορα,
Father, Almighty,
ποιητὴν οὐρανοῦ καὶ γῆς,
Maker of heaven and earth,
ὁρατῶν τε πάντων καὶ ἀοράτων.
of all things visible and invisible.
The full Creed is recited at every Divine Liturgy. These are its opening lines.
Πατέρες τῆς Ἐκκλησίας
The Church Fathers
The Church Fathers are the great theologians, bishops, and saints whose writings form the backbone of Orthodox theology. They did not invent the faith — they received it, defended it, and articulated it with precision and depth. Their writings are not merely historical documents; they are living voices of the Church.

Ἅγιοι
Key Orthodox Saints
The saints are not distant figures from the past. They are members of the same Body of Christ, alive in God, present to the Church. We venerate them — not worship them — and ask for their intercessions, as we would ask a friend to pray for us.

The Panagia — All-Holy — is the greatest of all the saints, the first among the redeemed, the Mother of God Incarnate.
St. Nicholas of Myra
